PRACTICAL
HOUSE PAINTER.
The following is an infallible and simple commercial
test of the purity of white lead:
“Take a piece of firm, close-grained charcoal, and near
one end of it scoop out a cavity about half an inch in
diameter and a quarter of an inch in depth. Place in the
cavity a sample of the lead to be tested, about the size of
a small pea, and apply to it continuously the blue or hottest
part of the flame of the blow-pipe; if the sample be strictly
pure it will, in a very short time, say in two minutes, be
reduced to metallic lead, leaving no residue; but if it be
adulterated, even to the extent of ten per cent. only, with
oxide of zinc, sulphate of baryta, whiting or any other carbonate
of lime (which substances are the principal adulterations
used) or if it be composed entirely of these materials,
as is sometimes the case with cheap lead (so-called), it cannot
be reduced, but will remain on the charcoal in an
infusible mass.
“A blow-pipe can be obtained from any jeweler at small
cost. An alcohol lamp, star candle, or a lard oil lamp
furnishes the best flame for use of the blow-pipe. This
test is very simple and any one can very soon learn to make
it with ease and skill.”
Always cut your japan in a little turps before you
add it to the paint. An ounce of japan, cut with
turps, will do better work than two ounces in oil
paint, if put in clear. Don’t add dryer to any more
paint than you can use up in a few hours, because it
will soon commence to fatten your paint in the pot
and lessen its covering and wearing properties. Many
a job has been spoiled by using old color, doped with
japan. Such paint is liable to mildew.
1st. It is too dark for light colored work, because
sooner or later it will show through in spots, or
darken the entire work.
2d. It leaves a rough, coarse surface which the
succeeding coats fail to completely level up.
3d. Succeeding coats are liable to scale from
cheap coarse ochre priming.
When paint scales from a tin roof it is not always
the fault of the paint. It stands the painter in hand
to carefully examine a new tin roof before painting
it. When the tinner uses rosin as a flux to make his
solder flow, the rosin is melted and cools again on the
tin. When such is the case, carefully scrape it off
with a knife, otherwise it will be liable to scale off,
and take the paint with it.
When acid is used in the place of rosin it is apt to
corrode the tin, hence it is best, if you want a permanent
job, to clean off the acid. To do this, first
rub the seams with kerosene oil, then wash with soap
suds and rinse with clean water. If the roof is quite
new, and the tin feels greasy, go over it with a wash
made of one pound of sal-soda to six quarts of water,
let it stand one-half day; then wash the tin with clear
water.
Instead of this method, I have given new tin a
good rubbing with No. 1 sandpaper to make it hold
the paint.
Below is an analysis of a sample of French ochre,
which is about the average of that pigment:

The oxide gives the color; the parts as given
above are in the right proportion to give the most
stable color and durable body to be found in ochre.
Here is an ochre, which was ground in a linseed
oil substitute, and sold to the trade at four cents per
pound in twenty-five pound cans, and retailed to the
painter at seven cents per pound in cans, to-wit:

The markets are flooded with such imitations of
ochre, both dry and in oil. The quantity of oil
required to grind pure French ochre makes it high-priced,
hence there is a motive for putting up barytes,
which takes but little oil in grinding.
Much of the so-called dry ochre on the market is
a yellow, iron ore and not yellow ochre. When mixed
in oil and put on a tin roof it will turn brown inside
of ninety days. I presume you have had experience
with such stuff. This makes a bad primer; it is very
liable to scale.
When paint crawls it is because there is not sufficient
adhesion between the undercoat and the new
coat, caused usually by too much gloss on the undercoat.
To prevent crawling subdue the gloss on the
undercoat by sandpapering, rubbing, or by the application
of some material which will have the desired
effect; or, if on the outside, wait until the
gloss has been subdued by the elements. There is
nothing more trying to one’s patience than to have
the paint let go and crawl up in bunches after it has
been carefully brushed out. Hence, it is well to provide
against such trouble in advance. The observing
painter has no doubt noticed that paint is more
liable to crawl under cornices, and upon other sheltered
positions, than elsewhere; hence, it is best in
all such sheltered places, where the elements do not
have full play, to use sufficient turpentine to prevent
a high gloss on the undercoats.
First, have a stick to open and shut the slats with
after you commence to paint. Second, leave a place
on each stile, or side rail, half way between the
hinges, six or eight inches long, unpainted, except to
cut in the edge next the end of the slats to take hold
of when you turn the blind over or set it aside; also
leave the bottom hinge unpainted. After you have
set up the blind hold it up by the unpainted hinge
until you finish the stiles; then lean it up against its
support and touch up the hinge. In this way you
need get no more paint on your hands than you
would in painting a door. No time will be lost,
because you can touch up the stiles in less time than
it would take to wipe your hands and brush handle.
Step-ladders without legs for outside work are
good things to have on the job. Say, three of them,
6, 8 and 10 feet long. A man of good height can
paint 14 feet high from the 10-foot ladder. They are
much easier on the feet than a “round” ladder. You
can stand straighter and reach farther when standing
on a step than you can while trying to balance on
a round stick; besides, a step is a handy place to set
your pail on.
Painting don’t pay, eh? No wonder it don’t pay,
because here you are spending half your time growling.
The facts in the case are, “You are not up-to-date.”
If there is no possibility of making money
at the trade, how is it that your competitor gets along
so well? Why is it that he accumulates and you
lose? He goes into the same market for labor, material
and jobs that you do. He comes out every
fall with his pockets full, and you round up poor as
a church mouse. There must be a screw loose somewhere
in your management. Will I point one out?
Certainly, we have always been friends, and I can
never do too much for a friend. In the first place
you are too impetuous. You forget for the time that
bills for labor and material will fall due, that you
must live—and you take the job at losing figures.
You ought to realize that the success of a contracting
painter depends upon his business qualifications.
To-wit: Correct and careful estimates, coolness in
bidding, care in selecting materials and men, systematizing
his work so as to keep each man in the
right place. I don’t know how much you are getting
for this job, but it looks to me that you are
losing money every day by using poor material and
improper handling of your men. The good business
man prefers the strictly pure Dutch process white
lead to the adulterated brands. He uses pure linseed
oil instead of adulterated mixtures and imitations
of it, and he never loses sight of the fact that a
good reputation is a mine of gold to him. If he finds
a man is a good hand on a ladder or swing stage he
keeps him there, and if he finds a man an expert at
inside work he keeps him there, and if he finds a man
is a poor stick in any place he lets him go, rush or no
rush. If he has high work he provides a safe and
easy way to get there. If he has inside work his
step-ladders are equal to the work. He knows when
a man has to reach too far or stand on top of a ladder
he can’t half work. Learn to manage your
men, to keep the right man in the right place. Stop
making ruinous bids. Open your eyes to the fact
that a man who makes a losing bid on a job, to beat
his competitor, acts like an idiot, and is meaner than
flies in paint.
The practice of estimating work by guess has
brought many a painter up with a round turn in the
fall in debt. The curious part of it is that the lesson
is rarely, if ever, learned. Don’t be too smart.
Guessing on work is very uncertain business.
A practical expert in an English journal, the
“Plumber and Decorator,” gives the following as his
process acquired and tested by many years’ experience.
The tools and materials required for glass gilding
are the same as used for gilding in oil, excepting the
gold size. Oil gold size would never do for glass
work. In glass gilding the object is to get a size or
mordant which will have the least possible tendency
to destroy or mar the burnish of the gold leaf. This
is absolutely necessary, when we consider that in this
kind of work the size is before the gold, not as in oil
gilding—behind it. For a mordant nothing can be
better than the best isinglass. To prepare this for
use the utmost care and cleanliness should be exercised.
The water must be quite pure—free from
grease or impurities of any kind. In preparing the
size the following may be relied upon as a first-class
recipe: Boil about one pint of water in a perfectly
clean pan. Should any scum rise during the operation
remove it with a large spoon. Then add about
as much isinglass as will lie on a dime to the boiling
water. This is best done a little at a time to prevent
it gathering in a mass before it has a chance of
dissolving. When the isinglass is dissolved strain the
size through a fine silk handkerchief, folded double
or fourfold, or, better still, through some white blotting
paper. This straining or filtering will remove
any bits or impurities that may have lodged unperceived
in the isinglass. When cool the mordant is
ready for applying to the glass. Some gilders like
to add spirit in some form—generally spirits of
wine—to their size. Their reasons for doing this are
not always very explicit. Some do it because they
have seen others do it. Others add it, they say, to
give the gold a better burnish, or to make it better
adhere to the glass. This is a delusion. The most
sensible reason for its use was imparted to me by a
veteran in the trade. He used spirits of wine to
take out or kill any slight greasiness that may have
been in the water or isinglass. I must confess that
until I learned this, spirits always formed part of my
mordant, because others used it. However, on further
consideration, its use has been discarded, and,
if anything, a better burnish on the gold is the result.
In making the size it must be borne in mind
that the less isinglass used the brighter will be the
gilding when completed. Of course, if too little
be used, the gold will not adhere to the glass as it
should, and this would cause much damage and annoyance
when the isinglass size was floated on again
to proceed with the second gilding. When the size
is too strong, or contains too much isinglass, no
amount of burnishing will remove it altogether from
before the gold. These are important points and
should be carefully studied. But a little practice
soon teaches the gilder how to arrive at the happy
medium.
There are a variety of purposes to which ornamental
glass gilding may be applied besides sign
work, shop fronts or glass doors. It is now much
used for show cases, window tablets, druggists’ bottles,
fixtures and pilasters for shop fronts. Very
often the design is embossed or bit into the glass,
and worked up with gold and silver leaf, besides being
picked out in colors. This is both a costly and
effective method of decorating, which shall have full
consideration in a future chapter. For the present
it will, no doubt, be advisable to consider the simpler
form of glass gilding. When this is thoroughly understood
very little further instruction is needed for
high-class work.
For the sake of example we will suppose a glass
slab about three feet six by twelve inches is the subject
to be treated. This is to have black letters without
thickness or shadow on a gold ground. There
are two methods of doing this. One is to first paint
on the glass the letters with japan black and afterwards
gild the plate. The other consists in first
gilding the plate solid and then painting in the
background with japan black. By this method the
lettering is left untouched. The gold on these is
then washed off, the edges trimmed, and the letters
themselves painted black or any other desired color.
This latter is, perhaps, the most satisfactory. However,
a few lines of explanation will be devoted to
each process.
First in order comes a plate, the letters on which
are painted with japan black previous to gilding.
To the learner, no doubt, the plain block letters will
prove an attraction, because of their simplicity. This
should be set out correctly on a sheet of lining paper.
It will only be necessary to run in an outline of
the letters. When completed to the satisfaction of
the operator it may be pasted round the edges and
fixed on the face of the glass. The back of the
glass, that is the side upon which the work is done,
should be quite clean. When the plate is fixed on an
easel or stand, which is the most convenient place
for working, the letters will, of course, read backwards.
In this form they must be painted. When
quite dry and hard, should the outlines of the letters
be irregular, they may be set right in a very
simple manner. All that is required to accomplish
this is a metal straightedge and a sharp
quarter inch joiner’s chisel. The straightedge is laid
across the tops and bottoms of the letters and the
chisel is employed to cut them sharp and true. The
sides of the straight letters are then similarly treated;
curves must be perfected with a writing-pencil. The
paper may now be taken from the face of the glass
and the plate examined all over. Should any
specks of black be found on it they must be removed
before the gilding is gone on with. The
smallest speck shows up before the gold leaf. If
convenient, before gilding, have the plate fixed at
an angle of about 45 degrees. While in this position
take a flat gilder’s mop and float the isinglass
size over the glass. Then take up the cushion, take
out a few leaves of gold from the book, and whilst
the glass is wet cover it with gold, lifting the gold
from the cushion as described in the last chapter.
If possible lift a whole leaf at once, but should
this at first prove troublesome try half a leaf. Keep
the glass wet with the size and overlap slightly each
successive leaf of gold until the whole of the glass
is covered.
The glass must now dry before it can be re-gilded,
and must then be gently rubbed with the
finest cotton wool. It is an easy matter to ascertain
whether it is dry or not. When wet the gold,
if looked at from the front of the glass, has a dead
look, but if dry it shows up bright. If possible
leave the plate till next day before giving it a second
coat of gold. The advantage of this delay is
obvious. The gold has time to get hard, which materially
reduces the risk of its being removed when
a second application of size is necessary.
To the novice it will, no doubt, appear at first sight
both a waste of time and gold to gild all over the
work again, but if the plate be held up to the light
it will show many imperfections in the shape of
small holes, cracks and imperfect joinings. Another
coat of size floated on and another layer of
gold over the whole of the work should turn out
a so far satisfactory finish. Let the glass dry
again and be subjected to a further examination for
faulty places. Should any be found cover them
with more gold. But if the work is satisfactory it
is ready for the burnishing process. The first stage
is to polish the gold by gently rubbing with fine cotton
wool, care being taken not to scratch the gold.
This is, of course, only a repetition of the polishing
after the first layer of gold.
There are several methods in general use for obtaining
that brilliant burnish so much admired in
glass gilding. But the one that meets with most
favor and success is what is called the “hot water
burnish.” It will be advisable to practice on the
glass under consideration. After the cotton wool
polishing is completed warm the glass either by holding
it before a fire or gently pouring warm water over
it. This is only a precaution against breakage by
sudden expansion. Now let it dry, and while warm
polish again with the cotton wool. Repeat the pouring
of water, hotter than the last, and when the
glass is dry, after this operation, gently rub it again
with cotton wool. This hot water flushing should
be carried on until the burnish is quite satisfactory.
But it must be very carefully done, else the gold runs
a risk of being washed off in patches.
Measure your work with the tape-line and be sure
you get all there is in it; projections, depressions,
mouldings, edges, etc.
Many a painter has dropped his profits by not
taking in these little particulars. Every bead, sunken
or raised panel makes an edge to paint. The edges
of ordinary weather boarding add ten per cent. to
the surface, to say nothing of the edges of the corner
boards and window and door casings—the projections
and depressions in the panels of an ordinary
four-paneled door, add at least ten per cent. to the
surface to be painted. Then let me say to you
again, look closely for edges, projections, depressions,
hollows and rounds. They all count when you paint
them; and it is your fault if they are not included
in the estimate. When you have multiplied the number
of feet around a house by the average height and
reduced it to yards you have only made a start.
Measure the cornice, follow the hollows, rounds and
edges with the line. There is lots of surface in
mouldings. The tape-line is good as far as you can
make it go, but it can’t do it all. You must use
judgment in connection with it; and carefully estimate
the condition of the work, what per cent. is slow
to paint, or high and difficult to reach. For instance,
what is the condition of the surface, is it porous and
full of cracks? Is every joint gaping for putty? Is
the putty on the windows rough and broken? Is
the old paint cracked, blistered and scaling? Is the
cornice ornamented with dentils, brackets and
panels? You may lose a day or a week of extra time
on a high tower or cupola if you fail to put it into
your estimate as extra hard to reach. Make the price
accordingly. Are the blind-slats stuck fast and difficult
to paint? Is the work to be done in the busy
season when labor and material are high priced and
good men are hard to get; or in the dull season, when
dealers will cut prices and good men are hunting
for work? Bidding on specifications must be done
with care. You can figure the number of yards to
be painted, but there are many points which the completed
job can alone disclose. A provision in your
contract to cover all changes in specifications comes
mighty handy on the day of final settlement. It is
not safe to make anything like a close bid on specifications,
until the following questions have been settled
and put in your contract. To-wit: Will the
building be delivered to you at a specified time, finished
and cleaned out and put in good condition for
the painter; or will you be expected to commence before
the work is finished and paint as the work is put
up, and spend as much time dusting and sweeping
as you do at painting? Will the machine-dressed
lumber, including mouldings, doors, window-stops,
etc., be put in as it comes from the factory rough and
fuzzy, or will it be redressed and made smooth and
ready for the paint? These points may look to you
like small matters, but they count when you come to
paint the work. If you are to do a fine job stipulate
in your contract that the wood-work, etc., shall be
finished in good shape. If you are to paint the work
as you find it have it so stated in your contract. Paste
this motto in the top of your hat and read it often:
“It is always better to lose a job than to get it and
lose money on it.”
Two houses may be of equal dimensions, yet it
may be worth 50 per cent. more to paint one than the
other; hence any definite scale of prices for work by
the yard is liable to be misleading. We may determine
by the line how much there is of the work, but
we must rely upon our judgment and experience to
determine how much it will cost to do it.
Find the surface measure of the entire job, including
all edges and projections, and estimate how
much it is worth per yard, on the basis that it is all
plain work, easy to get at. Next we will proceed by
what we may call special measurement. Suppose the
cornice measures 60 yards, and is finished with
blocks, moulded panels and brackets, and we estimate
that the cost of painting it will be three times that
of a plain cornice, hence we will add two measures
or 120 yards to the general or first measurement.
Next, suppose each window and casing measures
three yards, and there are 20 of them to be trimmed
in colors, we estimate the work of painting them
double that of plain work; hence we add to our
special measurement 60 yards. If there is a cupola
high and difficult to reach we estimate that it will
be worth double the cost of painting ordinary work
to do it. Say, it measures 50 yards, we will add
50 yards to the general measurement, and so we will
go on until we have taken in all parts of the work
which will cost more than ordinary plain work.
To illustrate: The building measures 600 yards,
and as plain work we estimate it worth twenty cents
per yard to paint it. We amount our special measurement
which we will say adds up to 300 yards,
which added to the 600 yards general measurement,
makes 900, which at twenty cents per yard, makes
$180. The same system may be used inside.
Break the putty into lumps; put it in a kettle with
enough water to cover it; add a little raw oil, and boil
and stir well while hot. The putty will absorb the
oil; pour off the water, let the putty cool, then work
it, and your putty will be as good as new.
During my experience as a painter, I have been
called upon to repaint tacky seats in at least half
a dozen churches. Such seats are an unmitigated
nuisance. Tacky paint may be the result of putting
too much japan in oil paint, or of using fat oil, or
paint which had been mixed a long time, especially
if it had very much japan in it, or by mixing oil and
varnish, or by putting varnish on oil paint, especially
if the paint had not been given time to dry hard
before it was varnished. To harden tacky paint try
this: Take one part japan and three parts of turpentine,
and give the work a coat of the mixture.
That will usually effect a cure, unless the paint is
soft clear to the wood. A coat of shellac will sometimes
do the work all right. Such seats usually
seem all right until warmed by the heat of the body;
hence we may be satisfied that the fault is in the
oil used in the paint or varnish. It is best on that
account to use but little if any oil when painting
seats of any kind. Coat up with color ground in
japan and thinned with turps; varnish the part which
comes in contact with the body with shellac varnish.
I have painted seats this way, and never heard of
any further trouble with them.
To repaint tacky seats the best way is to burn off
the old paint, and coat up as above; because, if a hard
drying paint is put over the old soft paint it is liable
to crack. It is well, however, to see if the turpentine
and japan will work a cure, or if a coat of shellac
will stop the trouble. To do this it is well to first
experiment on one seat, or upon a small surface.
I have killed tacky paint by rubbing it with a
cloth wet with ammonia; when dry, try it, and see
if the “tack” is gone; if not, go over it again; when
dry, put on a coat of shellac varnish; this is a pretty
sure cure.
If japan smells of benzine don’t buy it. Mix it
with clear oil; if it curdles, you don’t want it. Mix
drop black with some of it; as stiff as good drop
black ground in japan; then thin with turps and
make a painting test, to see if it is a good binder.
To see if it will crack, paint on glass, let it dry and
hold the glass between your eye and the light. If
you see fine cracks don’t buy any of it.
When you go to buy japan, ask the dealer who
made it. If he don’t know, make up your mind at
once that it is a fatherless waif without a name,
and likely to be worthless. When a man makes a
good thing he is apt to send his name along with it
as an advertisement. This applies to all material.
There is a great deal of bad japan on the market,
and a great amount of work ruined by it. Buy
none unless it bears the brand of a reputable maker
and will stand these tests.
I do not need to tell the practical painter that there
is a great amount of bad japan on the market, and
that a great deal of paint is ruined by it. Buy no
japan unless the can bears the name of some reputable
manufacturer, and will stand the above tests.
The following paper was read by Mr. A. P. Sweet,
of Iona, Mich., at a meeting of master car painters:
SUBJECT:
“Why do paints and varnishes crack, and what is
the reason that cracks in the latter are usually at
right angles to the grain of the wood?”
The subject, as I understand it, relates to the
cracking of varnishes, etc., as experienced in connection
with passenger car work, and as such I introduce
it for discussion before this association.
There are many theories as to the cause of the
cracking of paints and varnishes. Some are well defined,
others are not satisfactorily explained.
I do not anticipate being able to add much to what
is already known, but will advance a few thoughts,
which may call forth the views of others on the subject.
The old adage, “It takes two to make a quarrel,”
is as true when applied to paints and varnishes as it
is to individuals. A single coat of either seldom, if
ever, produces cracks. These make their appearance
only after two or more coats have been applied; consequently,
it is necessary to have a body of color or
varnish, consisting of two or more coats, before any
trouble of this kind makes itself manifest.
This being the case, it follows that the cause of
the difficulty must be sought for in the coatings
themselves, either in the quality of the material
employed or in the mode of applying them.
Poor and cheap oils and japans—especially the
latter—are a fruitful source of cracking in paint;
but by far the most prolific one, in my opinion, is
the hurried application of the succeeding coats before
the preceding ones are dry enough to receive them.
If sufficient time is not given, cracks will inevitably
follow such a mode of procedure.
I am of the opinion, also, that very little blame
can be attached to the wood used in the construction
of cars, as most of it is comparatively well seasoned,
and its expansive and contractive force is not sufficient
to cause serious trouble. If green wood was
used there might be room for this excuse, especially
where the cracks run in the direction of the grain,
and are large and deep.
Before pursuing this subject further, it may be
well to examine a little into the theory of the drying
of paint. It is purely a chemical process, not a mechanical
one, as some suppose. Paint dries by the
evaporation of its volatile parts and its absorption
of oxygen; it is heavier when dried than when in
the liquid form, having attached to itself a sufficient
amount of oxygen to very perceptibly increase the
weight some 6 per cent.
The best grades of linseed oil are said to contain
from 70 to 80 per cent. of substance called linoleine,
a resinous and slow-drying oil and acid which imparts
to the oil its elasticity.
In the process of drying, contraction occurs. The
various atoms of which the coatings are composed
move closer and closer together; and as this contracting
force is easier with than across the grain,
cracks at right angles to it are formed. This fact
suggests the necessity of so adjusting the elasticity
of the various coats that the force exerted in drying
may be as nearly equalized as possible, as their contracting
force is continued until all elasticity has left
the paint and oxygen ceases to be absorbed, all the
oil acid has disappeared, and nothing but a hard,
brittle surface remains.
Under the microscope, in the first stage of cracking,
the surface presents nothing unusual except that
the cracks appear clean cut and sharp on the edges.
As months pass by and the surface is exposed to the
atmospheric changes of heat and cold, wet and dry,
the cracks become more numerous; and in the last
stage, when the oil is entirely destroyed, the surface
assumes the appearance of innumerable rectangular
masses, higher in the center than at the edges, like
small mounds raised by the process of contraction
and adhesion.
Cracking in color coats may, by careful attention
to preliminaries, be reduced to a minimum, provided
good first-class materials are used and sufficient
time is given to each coat to dry.
Where varnish is to be applied as a finish, all coatings
should have oil in their composition and yet be
mixed to dry flat. They should be applied very
evenly and thinly, even if it necessitates an extra
coat, to cover and make a solid job.
Striping and ornamenting should be done on flat
color, which gives time for hardening, and fits it for
the varnish coats to follow. If work is done in this
way, I think very little fear of premature cracking
need be entertained; at least, not until time and
weather have sufficient opportunity to play havoc with
its beauty, and natural decay of the materials themselves
necessitates a thorough overhauling and repairing.
Rubbing varnishes are another source of trouble,
causing the succeeding coats of finishing varnish to
show signs of cracking long before they otherwise
would, as it does not agree with the slower drying
varnishes usually applied above it, being of a harder
and more brittle character, serving the purpose of
producing a fine, smooth surface, but sacrificing the
durability of the job.
Concerning the cracking of varnish, I have not
much to say. It seems to me that many of the reasons
given above will apply to it as well as to the
paint.
Poor material in the shape of varnish is poor indeed.
A first-class article only will give first-class
results.
It must be elastic, or it will crack easily and badly,
no matter how good the undercoats of paint may be.
Good varnish on good color coats will not give
any signs of cracking until, by repeated varnishings,
it has accumulated a thick coating of brittle, unelastic
gum.
No painter can say truthfully that his cars never
crack, as it is a natural consequence of decay, and
will come, sooner or later, to the best of material.
That varnish cracks to a great extent at right
angles to the grain of the wood, I think is due, in
some degree, to the same reasons as given above for
the cracking of paint, and after its elasticity is destroyed
by age. Vibration has a great effect upon
the hard and brittle coating of gum that remains,
coupled with expansion and contraction caused by
variations of temperature and the disintegrating influences
of the weather.
To make such a trough, take a piece of planed
board, 6 inches wide and 18 inches long, and nail on
side pieces 2 inches wide; this makes the trough.
Nail this trough on a bench, box, or table, and let one
end of it project over the edge of the bench, box or
table, and place your slush bucket under the projecting
end of the trough. To clean a brush, lay it in
the trough, keep hold of the handle with one hand
and with the other take a dull scraper and press the
paint out of the brush and shove it off into the slush bucket.
The advantage of this method is that you
clean the whole length of the brush and save the
paint, instead of daubing it on the walls of your
shop.
A good preparation for waxing floors may be
obtained as follows:
| Yellow Wax |
25 |
oz. |
| Yellow Ceresin |
25 |
oz. |
| Burnt Sienna |
5 |
oz. |
| Boiled Linseed Oil |
1 |
oz. |
| Turpentine |
1 |
gill |
Melt the wax and ceresin at a gentle heat, then
add the sienna previously well triturated with the
boiled linseed oil, and mix well. When the mixture
begins to cool add the oil of turpentine, or so much
of it as is required to make a mass of the consistence
of an ointment.
The burnt sienna may be used in smaller or larger
quantity, according to the tint desired, or may be
replaced by raw sienna, etc.
Never use damar varnish over oil paint.
Never put oil in damar varnish. See to it that
your dealer does not draw it into an oil measure, and
that you do not keep it in an oily or rancid can.
Why? Because it is liable to dry tacky under any
of the above conditions.
Ordinary plain staining can be done by almost any
one who can handle a common paint brush. Yet it
is not generally known, even to skilled decorators,
that stain, on sound white wood, evenly planed, can
be applied to imitate the most intricate of artistic
designs; such, however, is the case. A decorator
if asked to imitate in stain on white wood a piece of
parquetry or inlaid wood, might reply that such a
thing was impossible, alleging as a reason that by
employing liquid stain in the same way as a distemper—that
is to say, by the aid of a stencil to reproduce
the pattern—the stain, as soon as it became absorbed
would be found to “run,” and so giving to the
pattern imitated an indistinct or blurred edge. Yet
the most elaborate patterns are successfully stenciled
direct on to pine, and the figured work on this wood
has invariably come out distinctly and naturally as
to be almost indistinguishable from the inlaid work
they have so successfully sought to imitate. The
great difficulty to be overcome in stenciling with
stains is undoubtedly the “running,” but with a very
little care and patience this can be easily obviated.
Say a painter has a border to stain round an ordinary
pine floor in imitation of a selected pattern of parquetry,
the colors of which are generally in two or
more shades of oak, the first thing he has to do after
having properly prepared the floor—namely, making
the part to be stained as smooth and as even as possible
by filling up the crevices and nail holes—is to
stain over the work in the lightest shade shown in
his pattern; this can be done by diluting the ordinary
liquid oak stain with water to the desired tint.
Next let him cut out of a piece of lining, paper in
the form of a stencil—the pattern he has to reproduce
on the floor—care being taken to oil the stencil
in order to strengthen and preserve it. He should
then mix the stain into a stiff paste or to the consistency
of a distemper used for ordinary stenciling;
place a portion of this mixture on a smooth piece
of wood, take up a very small quantity of it on a
stencil brush and apply through the stencil plate in
the same way he would a distemper. If a very dark
shade is required apply more stain before removing
the stencil plate.
Objections: Chipping of the brick, and scaling of
the paint.
The chipping may be on account of defective brick
or otherwise.
Scaling may be caused by poor paint, or by dampness
in the brick.
When called upon to paint brick, first see if the
brick is dry. See that there is no place where water
leaks in from the roof or cornice and soaks into the
brick. A brick wall may look dry and still be damp
inside. If you want paint to stay on brick, give the
brick time to dry, after heavy and driving rains. It
is always a bad plan to paint brick in the fall, after
the autumn rains. The only real safe time to paint a
brick wall is in summer, after a spell of hot, dry
weather. You can not always wait for that, but you
can tell the owner that it is unsafe to paint a brick
wall until it has had time to dry. Why? Because in
winter the moisture, which is shut in by the paint,
will freeze, expand and throw off the paint or chip the
brick.
Prime brick work with a thin coat of good paint
mixed in pure linseed oil. Flow on the priming
freely, and brush it well into the brick; for second
coat, whatever paint you use, put in at least one-fourth
white lead; make this coat one-third turps,
and rub it well out. Give it a good body. For the
last coat, use your color regardless of lead, unless
you want it in to get your color. If you want a
gloss, mix this coat with all boiled oil, and flow on.
For flat, if your colors are ground in oil, use one-fourth
oil and three-fourths turps, and if it don’t
show flat when painted, it will flat in a short time.
The last coat may admit of more oil or may not take
as much, and flat. This depends upon the work
when started, etc. Some painters make brick flating
by breaking up the pigment in japan, and elastic
varnish for a binder, and thin with turps. I prefer
the oil for a binder, and have made the last coat
one-half oil, and had a nice flat in a few weeks. I
always ridicule the idea of painting brick flat, because
it will not stand as long as an oil finish, and
the oil finish will be flat enough in a few months.
Now, if I were going to teach a boy to clean up a
room, the first thing would be how to prepare himself
for the job. In the first place, he wants a damp
sponge with a string through it to tie over his head,
to hold the sponge over his mouth and under the nose
to catch the dust, because it is a great deal more pleasant
and a “sight” more healthful to carry lime and
other dust in a sponge than in nostrils and windpipe.
Then he wants a cotton cloth cap, large enough to
draw down over his head and ears, bib overalls and
jacket to button close about the neck and he is well
fixed. In such a rig he may look peculiar, but he had
better look like a monkey than to skin his nostrils
with dust and fill his ears and hair with lime, sand
and sawdust.
For tools, he needs a good, new, fine corn broom, a
wide bristle sweeper (a ten or twelve-inch paper-hanger’s
smoothing brush will do), a good duster,
a sharp tool to pick out corners, a two-inch chiseled
brush for corners. A sprinkler only turns dust to
mud, to dry in a few hours and become dust again.
When you have swept the floor with your broom and
dusted your wood-work and gone over the floor carefully
with your wide bristle brush to take what you
brushed from the casings and what the broom left
on the floor, look at the air across this ray of sunlight;
it is full of dust, soon the most of it will settle
on the floor and casings and window stools. What
then? Wait till it settles and wipe it off with a cloth
and don’t forget the tops of the doors and casings.
“Why use a cloth?” Well, if you go in and begin to
use a dust brush after the dust settles you throw a
portion of it in the air again and it will settle on the
work. And by the way, I want to say that a wiping
cloth is a very important article for a painter to carry.
It always makes me “red hot” to see a painter (?),
after he has daubed a key shield or a hinge, try to
wipe it off with his thumb; I could forgive him for
the daub; the best man in the trade may sometimes
do that, but the man who will rub part of it off with
his thumb and let the rest dry ought to be sent off the
job or suspended long enough to take a lesson in
the art of wiping off daubs.
I want to say further that every well regulated
dusting kit ought to have a dust pan hitched to it
in some way. It will save sweeping the dust out on
the steps to be tracked in again, save the time you
would lose in sweeping the dust over thresholds, or
save the time it would take to borrow one.
Make a stiff flour paste in the usual way, with
flour and water, then add 2 ounces tartaric acid, and
1 pint of molasses; boil the mixture until stiff, and
put in ten or fifteen drops carbolic acid.
| Wheat flour |
1 |
pound |
| Alum |
2 |
drams |
| Borax |
2 |
drams |
| Hydrochloric acid |
1½ |
ounces |
Mix the flour, alum and borax in the usual way,
to a smooth paste in water, then add the acid and
cook in the usual way with hot water.
To prevent tents, wagon covers, etc., from rotting
dissolve 4 ounces sulphate of zinc in 10 gallons of
water, then put in one-fourth pound sal-soda, stir
well until dissolved and add one-fourth ounce tartaric
acid. Let the cloth lie in this one day and night and
hang up to dry. Don’t wring it.
First stretch, then wet the cloth. Wipe off the
drops and letter while the cloth is damp with color
mixed with japan and turps.
A difficulty is often experienced in causing oil
colors to adhere to sheet zinc. Boettger recommends
the employment of a mordant, so to speak, of the
following composition: 1 part of chloride of copper,
1 of nitrate of copper and 1 of sal-ammoniac are to
be dissolved in 64 parts of water, to which solution
is to be added 1 part of commercial hydrochloric
acid. The sheets of zinc are to be brushed over with
this liquid, which gives them a deep black color; in
the course of 12 to 24 hours they become dry, and to
their now dirty gray surface a coat of any oil color
will firmly adhere. Some sheets of zinc prepared in
this way, and afterwards painted, have been found
to withstand all the changes of winter and summer.
When painting a blind never turn it upon edge
when cutting in the inside of the rail, because the
paint will be likely to run into the pivot-holes and
stick the slats. When you set a blind up to dry, set
the bottom end up, and be sure to have the slats lie
flat side up. Why? Because the bottom end of the
blind when hung is more apt to drag on the window
sill than the top end is to touch the jam above. If
set bottom end up, that end will dry solid and if
there are any sags it will be at the top. Keep the
slats flat side up to avoid flat edges.
First see that the floor is clean and smooth; then
give it a coat of best oil, with japan sufficient to make
it dry; cut the japan in turps. Then put on a good
mineral paste, filler in the usual way by rubbing the
filler well into the wood; then clean off all the surplus.
When dry, sandpaper and putty up well with
colored, hard putty, and put on a coat of shellac; if
too glossy, rub down with powdered pumice and oil.
Be careful to have the putty match the floor.
Take one-half pound of fresh burnt lime. Dip it
in water and let it slack in the open air. Melt two
ounces of bagundy pitch by gentle heat, in six ounces
of linseed oil; then add two quarts of skim milk
while the lime is hot, add the mixture of pitch and
oil, a little at a time while hot, and stir it in; then
add three pounds of bolted whiting and stir. Add
more milk if too thick for the brush.
Don’t forget to use the strainer. After you have
put in your best licks to clean up and sandpaper a
job, it is the height of folly to daub it up with paint
full of skins and specks. Oil paint is liable to be
“skinny” in the keg. Miller’s bolting cloth makes
a good strainer, and common cheese cloth at five cents
a yard does very well for ordinary purposes.
Use a wash of saltpeter or a thin lime wash, then
rinse with clear water. Treat blacksmith’s smoke in
the same way.
To please an old friend I give the following recipe
for kalsomine. He says it is good. I never used it,
so you will have to take his word for it.
Fifteen pounds good paris white, mixed up in lukewarm
water, add one-fourth pound good glue, dissolved
in the usual way, strain through a fine sieve,
then dissolve one-fourth pound white hard soap in
hot water and one-half pound of alum in cold water
and mix. Add water to give the right consistency
for putting it on the wall.
If you have an old, roughly painted door to cut
down for a fine job, don’t fool away your time, and
fill your nose with dust, trying to do it with dry sandpaper,
but take the door off its hinges, lay it flat on
horses, and keep the surface under your sandpaper
wet with benzine, and you can do in an hour what
would otherwise take half a day. The benzine softens
the paint, and keeps the paper from gumming up.
If it is not practicable to take the door off the
hinges, put your benzine in a small spring-bottomed
oil can and squirt it on the work as needed to keep
the paper clear of paint and make it cut fast. Wipe
off the loose paint with rags. It works equally well
on old varnish. Try it once on an old carriage body.
If the old paint is extra hard use a mixture in
equal parts of benzine and ammonia.
In the course of our work we often meet with
tarnished metal ornaments, which must be cleaned to
make our work look well.
This preparation is a good one:
| Paris white (fine) |
1 |
pound |
| Carb. magnesia |
2 |
drams |
| Cyanuret potash |
7 |
drams |
| Sulph. ether |
3 |
drams |
| Crocus martis |
1 |
dram |
| Soft water |
1½ |
ounces |
| or sufficient to make a stiff paste. |
Mix by rubbing, add the paris white last, then stir
into the water. Apply with a rag or sponge, and rub
dry and polish with a rag or canton flannel.
Some papers are more inclined to crack than
others, because they are made of more brittle material.
When selecting a paper for a whitewashed wall
or ceiling, take a pattern which feels soft and pliable.
Papers which crackle or rattle when crumpled in
the hand are liable to crack. Papers which stretch or
expand the most when wet are the most apt to crack;
because when they dry and shrink the pull is so
great that the fibers give away, if great care is not
taken in putting it on. Cracking may be the fault
of the paper hanger. He may use his paste too
thick, or too thin, or put on too much or too little.
Paste should be put on even and of the proper consistency
and thickness to cement the paper to the
walls. Paper is more liable to crack on rough and
uneven walls. On a smooth wall, if properly put on,
it becomes, as it dries, so fastened to the plaster that
it cannot contract enough to break the fibers, but on
a rough and uneven wall there are apt to be loose
places where the air gets in, and the contraction of
the paper so weakens the fibers that it cracks.
Now, if the paper hanger will be careful to secure
the paper uniformly by using sufficient paste on
rough places to hold the paper, and be careful to
brush or pound the paper down firmly, he will greatly
reduce the chances of cracking. A roller can not
be depended upon for a rough wall. Too much or
not enough sizing on a wall may be a cause of cracking.
Hot paste, which thickens as it cools, is not
safe to use on such walls, because it may appear just
right when hot but will be too thick when cool and
cause the paper to crack.
Oil size is good to use on a whitewashed ceiling
before papering if you don’t overdo it. A friend of
mine thought, if a little was good, a great deal would
be better; so he gave his ceiling two flowing coats of
clear oil, and when dry put on his paper, but it did
not stay. Why? Because he put on so much oil
that he made a glossy surface and the gloss could not
hold the paste. An oil size on whitewash is all right
if used right. It is a mistake to use clear oil; 1
pint of oil, 1 pint japan and 1 quart turpentine is
better, because it will penetrate further, dry faster,
flat the surface, and have sufficient binding power
to hold the whitewash from coming off. Don’t size
a wall with paste. Paste and whitewash don’t go
well together. The fact that you have to size your
wall to make paper stick proves this.
Oil size should dry hard before the paper is put
on.
I find glutol, manufactured by the Arabol Manufacturing Co.,
No. 13 Gold street, New York, a first-class
substitute for glue in wall size and kalsomine,
and prefer it to glue, because it will not attract flies,
nor spoil by standing in hot weather, and can be
mixed in cold water.
The white powder which comes on brick can be
removed by sponging with a mixture of muriatic
acid and water, equal parts. Wash the brick in clear
water and let them become well dried before painting.
Mix 1 part sulphuric acid with 12 parts water and
rub the zinc with it with a rag, then rinse with clear
water.
First get a good body and a smooth surface. The
work should be flat with three coats at least on wood,
and not less than two on iron or tin. The best size
for outside work is oil gold size (fat oil), mixed with
a little medium chrome yellow toned down with white
lead; put in a very little japan gold size, and thin to
workable consistency with turps; let it stand until
tacky. It must be hard enough to prevent rubbing up
or sweating. The method with the tip, gold knife and
cushion requires considerable dexterity as well as
practice to do good and rapid work. The tip, or lifter,
is only a few camel hairs glued between two pieces of
paste board, or other material. The knife is a long
narrow flexible blade, and the cushion is made on a
block, 6 by 8 inches, first covered with a thickness or
two of woolen cloth, and finished by stretching a piece
of chamois skin over it. Hold the gold book in the
left hand, and turn back a leaf of the book, leaving
the gold exposed on the next leaf; press the leaf of
gold against the cushion and it will remain. Then
straighten out wrinkles by a slight puff of the breath
from above, cut the leaf into the required size with
the gold-knife, and lift the leaf to its place with the
tip. The tip will lift the gold better if occasionally
drawn over the hair of your head.
Another way to prepare the leaf: Cut the book
through at the binding with a sharp knife, which will
leave all the leaves free and separate. Now take up
the top paper or cover, which will leave the gold leaf
on the book; lay the paper on a board and rub it over
with a piece of wax, paraffine candle, or a piece of
hard soap; either will do. Place the waxed side on
to the gold, and smooth the paper down gently;
repeat until you have as many leaves prepared as you
need. Then, with good sharp shears cut them in such
shape and size as will best cover your work, and not
waste the gold. Lay the pieces on your board, gold
side up. When ready, lay the pieces on the work, rub
down with the fingers, or a ball of cotton, take off the
paper and the gold will stay on the size. In this way
the gold adheres quite firmly to the waxed paper, and
the size must have a strong tack to take the gold off
the paper. Experts lay the leaf directly from the
book, and you had best learn to do it that way for
general work, if you spoil half a dozen books while
catching on to the knack of it. Try it this way:
Now, here is a stripe half an inch wide, and the size
is ready for the gold. Now hold the book flat in
your left hand with your thumb on top, hold the top
paper firm with your thumb. (If you let it slip, the
leaf under it will be spoiled.) If the stripe is one-half
inch wide, turn back enough of the paper to ex-pose
three-fourths of an inch of the gold leaf, crease
the turned back cover down with the fingers of the
right hand, and hold it with the thumb on the back.
Now cut the leaf with the finger-nail, first rubbing it
dry on your pants; then turn the book carefully
and quickly over on to the stripe, and press the gold
down gently by pressing the book. Then turn down
more of the paper, and repeat until that leaf is gone;
then take another and so on. If the book gets too
limber towards the last to handle well, have a square
of cardboard to lay under the book next to the hand;
you will find this is a help even with a full book.
You will, perhaps, waste more gold in this way than
by the transfer method, but you will more than
make it up in time, if you become expert.
1st. Be sure of a good foundation.
2d. Have your gold size right, and study to know
when the tackiness is just right. If your surface is
not perfectly free from tackiness, pounce with a bag
of gilder’s whiting before putting on the size, to keep
the gold from sticking outside of the size.
When you lay the leaf from the book and cut the
leaf with your finger nail, turn the ball of the finger
toward you and the nail towards the gold, and run
the nail close to the edge of the turned paper; then,
if the nail is not too long, the end of the finger will
hold down the paper while the nail cuts the leaf.
To prepare paper for the transfer method I rub
the paper on my hair, then lay it on the gold leaf,
gently rub it with my finger tips, and the leaf adheres
to the paper.
It can then be cut with shears in any desired shape
to cover the work.
Some gold leaf is now packed in paper so prepared
that the leaf will adhere to one side of it and can be
taken up in that way.
Some gilders take up the leaf by wetting the paper
on the back with turpentine to make the leaf adhere
to the other side, when it can be cut to the required
shape with shears. This is done instead of waxing
the paper.
It isn’t always your material that makes a bad job,
but it seems an easy matter to make even the best of
paint the scapegoat for bad work. The heedless workman
who primes a plastered wall without sweeping
down the loose sand, or is careless about taking the
sand and dust from the tops of casings and the floors,
will, if he stops to examine, find some in the brush
and some of it in his paint pot; and then, to cover
up his carelessness, he can lay the blame on the paint.
The careful painter will, when using heavy pigments,
carry a paddle, and not neglect to use it. To prevent
white lead and other heavy pigments from settling
in the pot the paint must be well mixed, and
kept mixed by stirring with a paddle as often and as
much as may be necessary to keep the oil or other
vehicle, and the pigment well incorporated. No one
out a novice, or a careless painter will permit a sediment
to accumulate in the bottom of his pot; no
matter whether the pigment is coarse or fine; or
whether the vehicle used is linseed oil, turpentine or
benzine. The painter who goes to work without a stirring
paddle in his pot will be liable to do uneven
work, and find more or less sediment in the bottom
of his paint pot at quitting time, because there is no
white lead made which does not contain more or less
particles sufficiently heavy to commence settling the
minute the paddle stops, and go to the bottom of a
pot of flating, as ordinarily mixed, inside of thirty
minutes, and other particles of smaller size will follow
later. If the pigment is mixed with oil the process
of settling is slower, but no less sure to take
place, and continue, if undisturbed, until clear oil
stands on top of the pigment. Don’t try to use your
brush for a paddle; it isn’t a good tool to stir paint
from the bottom. Paint made of heavy pigment
must be frequently stirred with a paddle to keep it
of uniform consistency, but this operation is too
often neglected. For instance, a man starts out with
a full pot in the morning and neglects to stir his
paint as he works, hence the heavier particles commence
to settle and soon get below the dip of the
brush, and by continual settling keep out of the
reach of it until they reach the bottom. When the
paint is nearly all out, and the sediment at the bottom
don’t work well, he refills his pot, leaving in the
coarse pigment. At night the boss finds an inch or
less of coarse paint in the bottom of the pot, and
without further inquiry complains that the lead is
sandy.
Another instance: The paint for a job stands
mixed over night; the painters fill their pots from
time to time during the day, but never stir the paint
from the bottom, hence the last pot or two filled will
have all the coarse pigment of the batch. There are
cases, I admit (too many of them), where not only
white lead, but dry colors and colors in oil, are too
coarse to work well, but the best white lead and heavy
colored pigments in oil or turpentine are liable to
be called sandy unless frequently stirred by the
painter.
Take annotto, 4 ounces, and clear rain water, 3
quarts. Boil in a brass or copper kettle, new tin or
galvanized iron will do, until the color of the annotto
is imparted to the water; then add ⅛ ounce potash,
and keep the mixture hot for 30 minutes; then, as
soon as cool enough to handle, it is ready for use.
Now, have the work free from dust, and spread on
your stain with a brush or sponge and rub it well
into the wood.
When the work is dry, rub lightly with fine sandpaper,
because the water stain will raise the grain
unless the wood has been filled.
You can suit the taste of the owner as to depth
of color by repeating the operation, or by making the
stain weaker or stronger, as the case may require.
These often come very handy to the painter, not
only in toning up new wood, but in renewing the
freshness of old work.
Spirits 1 gallon, gum sandarac 1 pound, shellac
½ pound, venice turpentine 2 ounces, dragon’s blood
4 ounces.
Shellac 1½ pounds, spirit 1 gallon, Bismarck brown
1 ounce, nigrosine ½ ounce. You can, by varying the
proportions of the two colors, make the shade as you
like it.
(Spirit in this connection means either wood or
grain alcohol.)
Spirits 1 gallon, shellac 1½ pounds, Bismarck
brown R ½ ounce, nigrosine 30 grains. More nigrosine
will make the stain darker. If this is too thick to
work well, thin with spirits.
Sponge it with a strong hot solution of common
soda in water. This will raise the grain, hence it
will require cutting down with sandpaper.
Make a solution of bi-chromate of potash, 1½ ounces
to 2 quarts soft water. Lay on the solution with a
good clean sponge and keep the wood wet with the
solution until it is dark enough to please you. Then
wash off the potash with clean soft water.
Apply with a brush, strong aqua ammonia until
you get the desired shade.
Fill a
bottle ⅓ full of red saunders, then fill the
bottle with either wood or grain alcohol. The more
red saunders you put in, the stronger will be the
stain; you can dilute it for the lighter shades. The
longer it stands, the more color will be extracted.
Always strain through muslin before using.
Red saunders makes a good cherry stain. When
used on the bare wood it requires no binder, but when
used over filled or oiled wood, put in one-fourth as
much shellac varnish as you have stain, to act as a
binder for it. If you want it to act as a filler as well
as a stain, for pine or other close-grained wood, add
1½ pounds corn starch, to each gallon of the mixture
of stain and shellac. Try a little and if it rubs up
when dry, add more shellac.
You can mix red saunders stain with asphaltum
varnish, to make black walnut and mahogany stains,
using more or less of either to give the desired shade
by using turpentine to make them mix. The asphaltum
acts as a binder in place of the shellac.
The practical painter can get the shades he wants
by experimenting on this line.
First give it a coat of very thin asphaltum varnish,
then, when dry, give it a coat of red saunders and
shellac.
You can mix the red saunders and asphaltum stain
with any turpentine varnish, or with spirit varnish, if
you use turpentine to make them mix.
Burnt umber and burnt sienna in oil or varnish
make a walnut stain. Use but little of the pigments
in proportion to the oil. Too much pigment gives
the work a muddy color.
Clean up all soiled places on the wood. To be
sure of a good job on open grained wood use a Bliss
Rock Wood Filler. If you use a ready made filler,
thin as per directions on the can. Whatever filler
you use, put it on with a good brush. As soon as
the filler begins to set, or show flat, commence to rub
it into the grain with a pad made by gluing a piece
of harness leather onto a block; always when practicable
rub across the grain of the wood. For round
work have a long piece of leather to draw back and
forth around the work. Remember the main thing
at this stage is to get as much of the filler as possible
rubbed into the wood.
Another important point is to take off the surplus
filler before it becomes too hard to wipe off, and
another point is to wipe off the surplus filler and
leave the pores of the wood level full. Hence, it
is important that the filler does not dry too fast,
that the painter puts on no more filler at a time
than he can handle before it dries, and that in wiping
off the surplus filler he works his rags across the
grain. Some very open grained wood requires a
second application of filler to make a good job, or at
least to be looked over and touched up. The filler
should have at least two days to dry. When dry go
over it lightly with fine sandpaper to take off all
particles of filler left on the surface.
Walnut, mahogany, chestnut, oak, ash and butternut
may be classed as open grained woods, which
need to be well filled with paste filler colored to
match the color of the wood. When the filler is dry
put on a coat or two of white shellac and rub down
smooth with No. 1 sandpaper, and follow with two
or more coats of hard oil or varnish, as you like; give
each coat plenty of time to dry and rub each coat
with curled hair or hair cloth, except the last coat.
If you want an egg shell or half gloss, rub the last
coat with pulverized pumice stone and raw linseed
oil. If you want a dead finish rub down with pulverized
pumice stone and water instead of oil. If
you want a polish, first rub with the pumice stone
and water; then with rotten stone and water, and
polish with rotten stone and oil, or furniture polish
and rotten stone. If you want a gloss finish,
flow on the last coat and omit rubbing. Treat the
close-grained woods as above stated, with the exception
of the filler. The shellac also may be omitted,
but it will take at least one more coat of hard oil or
varnish for the job.
Cherry, sycamore, maple, birch, gumwood, redwood,
cypress, pine, whitewood, poplar and hemlock
are all close-grained woods, and need no paste filler.
Pine especially should have a coat of shellac to keep
back the pitch.
For an extra fine job of gloss finish, rub next to
the last coat with pumice stone and water, flow on a
coat of good varnish, and leave it in the gloss. In
this case great care is required in cleaning the work
to keep it from showing specks.
It stands the beginner in hand to be careful and
not use his shellac too heavy to work well; shellac
has good body and an apparently very thin coat will
be a good heavy one.
To do a fine job the room and work must be clean,
the clothing free from dust, and the work, brushes
and varnish free from specks. If specks show on
your gloss coat call a halt, and find where they come
from.
Soft cotton rags are the best material for wiping
off surplus filler.
A felt pad of convenient size to handle is the best
for rubbing work. Get one at the furniture shop.
For a cheap job omit the water rubbing, and rub
with pumice stone and raw oil.
Take powdered white shellac 1½ pounds, best grain
alcohol 1 gallon. Add the gum to the alcohol, set
it in a warm place and shake your jug or bottle
occasionally. Don’t put it in tin or iron; either of
them will discolor it. You can hasten the process by
setting your jug in a sand or water bath, and gently
heating it; or set it by the stove, or in the sunshine.
To make the common orange shellac of commerce,
dissolve 1½ pounds orange shellac in 1 gallon methylated
spirit or grain alcohol. This will dry in ten
or fifteen minutes, and makes a hard lustrous varnish
when dry, and stands the weather better than most
gum varnishes. It makes a turbid liquid of orange
brown hue and dries rather a pale brown. For use
on dark wood this is equal to the white shellac, if not
superior.
There is no use in trying to color common putty to
match the color of natural wood. The whiting in it
will not take clear tints. Use lead putty, which you
can tint with raw sienna for pine, yellow ochre for
oak, burnt umber and burnt sienna for walnut, and
burnt sienna for mahogany. Better have the putty
too light than too dark.
Poor lumber and thin painting are often the cause
of spots on paint, especially on two-coat work. On
cross-grained and other extra-porous places more of
the oil sinks into the wood than on the general surface,
and the result is flat places in the paint, which
fade sooner than the glossy paint; hence, the work
looks spotted.
To provide against this kind of spotting use more
care in priming and see that all extra-porous places
are well filled with the prime coat, or touch them up
before the second coat goes on. A little extra work
with the brush when putting on the prime will save
trouble.
Another cause may be traced to the practice of
putting on a coarse dark priming coat, which will
show through in places where the paint is thinnest.
Mildew, or fungus growth, is another cause. This
sometimes comes from the use of too much japan,
poor or fat oil, or when the paint dries tacky or soft.
Adulteration of linseed oil with mineral and other
non-drying oils, has a tendency to make paint dry
soft. Linseed oil, kept for a few days in an old sour
tank or in an old rancid can in the paint shop, is
liable to cause fermentation to take place, which may
result in mildew in damp weather in shaded places.
When an oil can smells sour, or there is a deposit
of foots at the bottom, it is unfit to keep oil in.
Another cause of spotting may be found in insufficient
and improper brushing or spreading the
paint; especially the priming, which requires as
much care in putting on as any other coat on the
job.
For instance, here is a job which shows “laps.”
Now, if this prime is right when it is put on single, it
is wrong when it is put on double, because, where the
laps are, the work has at least one more coat than
the balance of the job, hence the paint is liable to
fade spotted.
All different names for about the same thing. To
make a fine job: If the work is new, see that it is
smooth, free from dust and stains. Then give it a
coat of priming, put on thin, so as not to show
brush marks, and rub down with No. 0 sandpaper.
Next, get a good body with keg lead, mixed in turpentine
and a very little linseed oil; put on thin
coats, so as not to show brush marks; use a fitch
brush, or at least a fine bristle chiseled brush. When
dry, rub down with sandpaper and flow on a coat of
thin white shellac. This is to keep back the oil in
the lead coats, and prevent chemical action between
the lead and zinc coats. Next, put on two or more
coats of French zinc ground in damar varnish;
enough at least, to get a clear white. Thin with turps
and a little damar varnish, and put on thin enough to
show no laps or brush marks.
Then put on a coat or two of French zinc ground
in damar varnish, thinned with 1 part damar varnish
and 2 parts turpentine. Next put on a coat of damar
varnish mixed with a little zinc ground in
damar, just enough to make the varnish white. Flow
on a coat, and be careful that it does not run on
your work. To avoid runs always commence at the
top of a panel with a full brush and work down so
as not to have a surplus in the lower corners of the
panels; this applies to all parts of the work. It is
quite a knack to put on a full coat of this varnish
and zinc, and not have it run.
In all cases put on enough zinc coats to make a
clear white before you put on the varnish. The small
quantity of zinc is put in the varnish to take off
the yellow tinge, and to keep it from turning yellow.
Use lead putty. See recipes to make it on another
page.
Very hard and white, for parlors.—To prepare
the wood for the finish, if it be pine, give one or
two coats of the “Varnish—Transparent for wood,”
which prevents the pitch from oozing out, causing the
finish to turn yellow; next, give the room, at least,
four coats of pure zinc, which may be ground in
only sufficient oil to enable it to grind properly;
then mix to a proper consistency with turpentine or
naphtha. Give each coat time to dry. When it is
dry and hard, sandpaper it to a perfectly smooth
surface, when it is ready to receive the finish, which
consists of two coats of French zinc ground in, and
thinned with damar varnish, until it works properly
under the brush.
White lead may enter the human system in three
ways, to-wit: Through the stomach, the lungs and
the skin. In other words, it may be eaten, inhaled
or absorbed, hence the stomach, lungs and skin
should each be carefully guarded against it. To
guard the stomach, through which you are in the
most danger of taking in the poison, make it a rule
to keep the mouth closed as much as possible when
using white lead, and especially when sandpapering.
Make it a rule to never eat or drink without first
carefully cleansing your lips, and carefully removing
the paint from your hands before eating. Tobacco
chewers, who carry tobacco in their pockets, are in
especial danger of lead poison, if working in paint,
because the tobacco becomes more or less poisoned
with lead from the fingers, if the painter is not careful
to clean his hands before taking a chew. There
is no great danger from inhaling white lead, except
when sandpapering, or when dusting after sandpapering.
It is a pretty good thing to carefully guard the
nose with a damp sponge while sandpapering, and
to carefully free the nostrils from lead. There is
no danger of poisoning by absorption through the
skin, unless the painter is careless. When T see
some men at work, I wonder how they can possibly
escape lead poisoning. Their clothing glazed with oil
paint, their hands daubed to the wrist by grasping
the brush by the head, instead of by the handle; or
by general carelessness in mixing and handling
paints.
Tired feeling, wakefulness at night, neuralgic
pains, “shaky” hands, constipated bowels, bad taste
in the mouth, and pain in the bowels, a blue edge on
the gums, and a coated tongue. If you get the
colic, see a doctor; for the other symptoms, get away
from paint for a while if possible, and take the
following: Iodide of potash, ½ oz.; syrup sarsaparilla,
8 oz. Dose:—Teaspoonful three or four times a day
in half a cup of milk. Eat graham mush and drink
milk.
First fill the wood with any good filler. Fill it
well, then take Vandyke brown 3 parts, and burnt
sienna 1 part, and mix to a stiff paste with boiled
oil and japan, and thin with turpentine, until you
can brush it on the wood, and not have it look dauby
or muddy. Give the work a light coat, and brush
it out well and carefully. Too much pigment will
make your work too dark. Wherever you want the
light or worn spots to appear, wipe off the stain
with a cloth, and with a badger blender carefully
blend the stain into the edges of the worn or light
spots. Don’t stain too much at once, for fear your
stain may set so you cannot wipe out and blend.
When the stain is dry, sandpaper lightly with No. 0
paper. Finish with two coats rubbing varnish, or
with hard oil finish. Polish with rotten stone and
raw oil.
A very superior article may be made by dissolving
3 parts of india rubber in 30 parts of naphtha;
heat and agitation will be required to effect the
solution; when the rubber is completely dissolved,
add 64 parts of finely powdered shellac, which must
also be heated in the above mixture until all is dissolved.
This mixture may be produced in sheets like
glue by pouring it while hot upon plates of metal,
where it will harden. When required for use, it
may simply be heated in a pot till soft. Two pieces
of wood or leather, joined together with this glue,
can scarcely be sundered without a fracture of the
parts.
We find the following recipe good: The compound
of glycerin, oxide of lead, and red lead, for mending
cast-iron that has been fractured with the happiest
results. It takes some little time to dry, but turns
almost as hard as stone, and is fire and waterproof.
For mending cracks in stone or cast-iron ware,
where iron filling cannot be had, we think it is invaluable.
Take litharge and red lead, equal parts,
mix thoroughly and make into a paste with concentrated
glycerin to the consistency of soft putty, fill
the crack and smear a thin layer on both sides of the
casting so as to completely cover the fracture. This
layer can be rubbed off, if necessary, when nearly dry,
by an old knife or chisel.
The oleaginous principle of linseed oil is said to
be in the nature of neutral salts called linolein, consisting
of linoleic acid combined with a glycerine
base. Linolein is said by some writers to constitute
three-fourths of the volume of linseed oil, and that
the drying properties of the oil reside in the acid
principle of the linolein; that is, linoleic acid has the
property of attracting and combining with oxygen
to form the substance known as dry linseed oil. This
acid is said to be a compound of several different
acid principles, combined in definite proportions.
Writers seem to disagree as to what the acids are,
and in what respect they differ from the acid properties
of the non-drying fixed oils, but that is a
question which need not be discussed here. The
glycerine base of linolein seems to be common to all
fixed oils, and is set down as an oxide consisting of
one equivalent of water and five of oxygen; hence
the affinity between the linoleic acid and its glycerine
base.
Linoleic acid, like other acids, has an affinity for
alkalies and the ordinary metallic oxides. It unites
with them, forming neutral compounds. This affinity
is said to be electrical; the alkalies and oxides
electro-positive, and the acid electro-negative. The
greater the contrast in this respect, the stronger the
affinity; hence, some acids separate others from
their bases and form new salts by precipitation. As
an instance:
Drop sulphuric acid into a solution of acetate of
lead. It will displace the acetic acid, form sulphate
of lead and precipitate, leaving the liberated acetic
acid in solution. In linolein, this acid is so constituted
that the affinity, or attraction between it and
its glycerine base, is too feeble to resist and keep
back the oxygen of the air; hence, when linseed oil
is exposed to the air in a thin layer, oxygen unites
with its linoleic acid, and this process continues until
the oil becomes dry to the touch. Beyond this
point the process is slower, because the oil is now
less penetrable; but the process goes on until the
layer of oil becomes hard and brittle, no matter
with what pigment it may be mixed, although the
pigment may for a time retard the action of the
destroying elements.
Linseed oil dries too slowly for general use by the
painter, hence various ways have been devised to
hasten the drying process. If the foregoing theory
is correct, the process which will cause the oil to
dry to a good wearing body in the time desired, and
leave it in the best condition to resist the action of
the elements and the absorption of oxygen, is the
best. I regard the lead oxides as the best dryers
for this purpose—at least according to my experience.
When we add an oxide to linseed oil as a
dryer in the small quantity which experience has
taught us is best to use, it is evident that it is not
sufficient in itself to oxidize the whole of the oil to
an appreciable extent. Writers differ as to the peculiar
action of the oxides upon the oil, but I think it
safe to say that the dryer sets up some chemical reaction
which increases the affinity between the linolein
and the oxygen of the atmosphere; at any rate,
there is no dispute upon the point that linseed oil
in drying absorbs a large per cent. of oxygen.
A knowledge of this unanimously conceded point
led me to believe that a coat of pure linseed oil
might make the best possible priming coat for iron
work which had commenced to rust. Why? Because
iron rust is an oxide of iron, having an excess
of oxygen. Spread on rusty iron, it penetrates the
rust, absorbs its excess of oxygen and dries with the
remaining neutral oxide held fast in its body. This
is my theory; whether correct or not, numerous
tests have proved to me that a coat of linseed oil
will stop the rusting of iron if applied under proper
conditions. When rust is thick or scaling there is
no safety short of taking it off. Iron rust is more
or less hydrated; to free it from moisture, give it the
flame of the gasoline paint burner.
First, the wood is primed with a composition consisting
of three parts of turpentine and one part of
oil, japan gold size being used as a dryer. On this
drying thoroughly the work is rubbed down until
perfectly smooth. Next are applied two or three
coats of pure white lead mixed entirely flat; each
coat is rubbed down, time being allowed for it to
dry. Equal parts of lead and zinc are used for the
next coat, and three-fourths zinc and one-fourth
lead for the one succeeding. After this has become
thoroughly hard it is rubbed down very smooth. A
thin coat of color made of zinc and turpentine is now
rubbed on; for the next coat the same flat color is
used, with the addition of about one-half the quantity
of good light coach varnish. For the last coat
enough zinc is used in the varnish to make it white
if the last coat of zinc is not white and solid before
varnishing. If the work is to be gilded or striped
the zinc must be left out of the last coat of varnish.
An expert has sent the following to the British
Journal of Photography: To make a varnish to imitate
ground glass,
dissolve 90 grains sandrac and 20
grains of mastic in 2 ounces of washed methylated
ether, and add, in small quantities, a sufficiency of
benzine to make it dry with a suitable grain—too
little making the varnish too transparent, and excess
making it crapy. The quantity of benzine required
depends upon its quality—from half an ounce
to an ounce and a half, or even more; but the best
results are got with a medium quality. It is important
to use washed ether, free from spirit.
One quart of boiled linseed oil and two ounces of
asphaltum, to be boiled on a slow fire until the
asphaltum is dissolved, being kept stirred to prevent
its boiling over. This gives a fine dark color, is not
sticky, and looks well for a year; or, first wash the
article with soap and water, and when dry, on a
sunny day do it over with common boiled linseed
oil; leave that to dry a day or two, then varnish
it over once or twice with hard varnish. If well
done this will last for years and prevent annoyance
from insects.
Rub some bi-chromate of potassa fine, pour over
it about twice its bulk of sulphuric acid, and mix
this with an equal quantity of water. The dirtiest
brass is cleaned in a trice. Wash right off in plenty
of water, wipe it and rub perfectly dry, and polish
with powdered rotten stone.
In order to do this well, your foundation or
ground-work must be perfectly smooth and white,
or nearly so, you then gild it with silver leaf with slow
size, so as to have it perfectly smooth with no ragged
edges, cleaning the loose leaf off. Then grind cologne
earth very fine, and mix it with gum water,
common size; and with this, you having added more
gum water than it was ground with, spot or cloud
the ground-work, having a fine shell to imitate; and
when this is done, you will perceive several reds,
lighter and darker, appear on the edges of the black,
and many times lie in streaks on the transparent
part of the shell. To imitate this finely, grind
dragon’s blood with gum water, and with a fine
pencil draw those warm reds, flushing it in about the
dark places more thickly, but fainter and fainter and
thinner, with less color towards the lighter parts,
so sweetening it that it may in a manner lose the
red, being sunk in the silver or more transparent
parts. When it is dry, give it a coat of varnish,
let it stand for a few days, then rub it down with
pumice stone and water. Then grind gamboge very
fine, and mix with varnish, giving of this as many
coats as will cause the silver to have a golden color,
then finish with a clean coat of varnish.
The prices of labor, and cost of material vary so
much in different localities that it seems impossible
to make a reliable price list for general work. The
position, condition, and shape of different jobs all
go towards making a general price list, an unreliable
guide; also the quality of work demanded may make
50 per cent. difference in price. I have half a dozen
printed price lists before me, and they generally
agree to about the following prices for painting and
glazing, to-wit:
|

| 1 coat on new work |
8 to 10 cents |
| 1 coat on old work |
10 to 18 cents |
| 2 coats on new work |
18 to 20 cents |

20 to 25 cents |
| 3 coats on new work |

15 to 18 cents |
| 24 × 30 |
20 to 25 cents |
| 30 × 40 |
35 to 50 cents |
For old work where the old putty is in the sash,
multiply the above figures by 3 or 4. When called
out to the house to set a light or two charge for
time and material. Most work of this kind is done
at least 30 per cent. below the above prices.

All things considered, which is the best time of the
year to do outside painting? Spring and fall, did
you say? Well, yes. I know nearly all painters think
so, and the people outside the trade are almost, if
not quite, unanimous in holding the same opinion.
But why? Do the winds of March, the frequent
showers of April and May add very much to the
pleasure and profit of doing outside work in spring?
Do the soaking rains, which come along about the
time of the vernal equinox and drive you off your
job for a week or two and watersoak your unprimed
work, add much pleasure to your recollections of
spring painting? Do you remember anything about
the clouds of midges and thousands of little moths
which filled the air, ready and willing to decorate
your paint with their little bodies on every still,
warm mid-day in April and May? Of course, we
are speaking now of climatic conditions from
our own standpoint, the great Northwest, which may
also be true in the Middle and New England states.
The mornings and evenings of spring and fall are
apt to be cool—often frosty; then the oil stiffens and
the paint rubs out hard and goes on slow, and we
lose time and work harder. Practically, I favor midsummer
for outside work, because the temperature is
more uniformly warm and the paint spreads easily
and evenly at any time of day, and as a rule the
rains are less frequent and give a longer warning of
their approach. The little black flies are not so
plentiful in the hot days of summer as they are in
spring and early fall. They are either dead or seek
the shade of trees and grass. The dew is all gone
in summer before seven o’clock a. m., and does not
commence to fall until after quitting time. A carpet
of grass and other vegetation covers a large portion
of the ground in summer, holding down the
dust. The winds are not usually so high and gusty
in summer as they are in the spring and fall. In
the warm days of summer your work is more apt to
dry quickly, cleanly and evenly; and when you
“knock off” from work at six p. m., and the sun is
yet two hours above the horizon, you know that your
last ground stretch will soon be out of the way of
dust and rain. In the hot weather of summer the
pores of the wood are all open, and the oil, which is
then soft and thin, goes farther into the wood than
in spring and fall, when the weather is cool. There
are, it is true, some fine days in the fall for outside
work, but the rainy season of the autumnal equinox
and the frosty nights of the later months often retard
your work and mar the finish of your job. One
objection urged against summer painting is the
flies, but really are the flies which injure paint any
more numerous in midsummer than they are in
spring and fall? It is true the festive house-fly is
in his glory in the summer, but, as a rule, he is too
smart to get stuck in outside paint. To get inside
is his ambition, and the molasses-cup and sugar-bowl
are his objective points. If the house-fly is an
objection in the summer, it certainly is a greater one
in the fall, for in September and early in October
they are thicker, saucier and more familiar than at
any other time of year; then they want not only to
get at the sugar, but to get in and warm.
A correspondent asks: “Does the reader know
from practical experiment that one season is better
than another for applying outside paint?” I suppose
the writer means the effect upon the wearing
qualities of the paint and the permanency of the
color. I have been experimenting for a practical
solution of this question for my own satisfaction
and guidance, and have come to the conclusion that
paint put on the outside in the hot weather of summer
will wear as well and hold its color as long as
paint put on in the cooler days of spring and fall.
I know the idea that paint dries too fast in hot
weather is almost universal, but I think it grows
largely from the fact that a quick-drying paint is
not as good for outside as a slow dryer; but you must
remember that there is a great difference between a
quick-drying paint and drying a slow paint as
quickly as the ingredients will admit of. Linseed
oil dries or hardens by absorbing oxygen from the
air, and that process goes on more rapidly in hot
weather than in cool weather, because the air in hot
weather is in a condition more freely to part with
its oxygen, or because the oil is in a better condition
to receive it, or both. In other words, a warm atmosphere
hastens the process of absorption and a
cool air retards it, but in either case the result is
the same: the air gives up enough of its oxygen to
solidify the oil. Now, the question arises, can any
difference be discovered (chemical or otherwise) in
the composition of the paint, whether dried in warm
or cool air? From a business-point of view, I have
long advocated summer as a good time to paint outside,
and have usually succeeded in converting customers
to my views upon the subject, and as a consequence
have not often had a dull time in midsummer.
We painters in the country know how unpleasant
and unprofitable it is to have all the work
of the year rushed upon us in the spring and fall,
and I think if painters generally could convince
themselves by practical experiment that, all things
considered, summer time is the best season of the
year to do outside work, and advocate the same to
their customers, backed by argument and practical
illustration, there would soon be less need of complaint
about a dull season in midsummer.
1. An expeditious way is by chemical process, using
a solution of soda and quicklime in equal proportions.
The soda is dissolved in water, the lime
is then added, and the solution is applied with a
brush to the old paint. A few moments are sufficient
to remove the coats of paint, which may be
washed off with hot water. The oldest paint may be
removed by a paste of the soda and quicklime. The
wood should be afterwards washed with vinegar or
an acid solution before repainting, to remove all
traces of alkali.
2. Wet the place with naphtha, repeating as often
as required; but frequently one application will dissolve
the paint. As soon as it is softened, rub the
surface clean. Chloroform mixed with a small
quantity of spirit ammonia, composed of strong ammoniac,
has been employed very successfully to remove
the stains of dry paint from wood, silk, and
other substances.
3. To remove paint from floors.—Take one pound
of American pearlash, three pounds of quickstone
lime. Slake the lime in water, then add the pearlash,
and make the whole amount about the consistency
of paint. Lay the mixture over the whole body
of the work which is required to be cleaned, with an
old brush; let it remain for twelve or fourteen hours,
when the paint can be easily scraped off.
1. Take three pounds of quickstone lime; slake the
lime in water, then add one pound of American
pearlash; apply this to both sides of the glass and
let it remain for twelve hours, when the putty will
be softened, and the glass may be taken out without
being broken. To destroy paint, apply it to the whole
body which is required to be cleaned; use an old
brush, as it will spoil a new one; let it remain about
twelve or fourteen hours, and then the paint may be
easily scraped off.
2. To remove paint from old doors, etc., and to
soften putty in window frames, so that the glass
may be taken out without breakage or cutting, take
one pound of pearlash and three pounds of quicklime,
slake the lime in water and then add the
pearlash, and make the whole about the consistency
of paint. Apply to both sides of the glass and let it
remain for twelve hours, when the putty will be so
softened that the glass may be taken out of the
frame without being cut, and with the greatest facility.
To destroy paint, lay the above over the whole
body of the work which is required to be cleaned,
using an old brush, as it will spoil a new one. Let
it remain for twelve or fourteen hours, when the
paint can be easily scraped off.
3. Paint stains on glass.—American potash, 3
parts; unslaked lime, 1. Lay this on with a stick,
letting it remain for some time, and it will remove
either tar or paint.
There are two classes of damp walls, first where
the water comes in from the outside from defective
roofs, bad gutters, defective pipes, and where it comes
through the walls from the ground, as in basements.
In the other class we may include walls which are
dampened by condensation of moisture, in places
shut off from the general artificial temperature of
the room, behind stationary furniture. Such walls
may dry out during hot weather, or they may be kept
damp by a growth of mold or fungus.
When water comes in from the outside, it is impossible
to keep paint or paper on the wall in good
shape. Look around for the places where the water
comes in, point it out to the owner, and if he fails
to stop the leak have it understood that the work is
done at his risk; or, what is better, refuse to do the
work; because, when a job comes off, or turns out
badly, you will take the blame generally, no matter
whether it is your fault or not. A job may be made
to last awhile by a waterproof coating, or by sheathing
with thin lumber, but it is only a question of time
when the lining material will become water-soaked
and spoil the paint or paper, to your discredit. I
have usually been too busy to take jobs of this kind.
If the water can be cut off, the next thing is to dry
the wall, which you can do at the surface only by
setting a stove near it, or with the flame of a paint
burner; then, after all your trouble, the water, which
remains in the wall, if of brick or stone, may find its
way to the surface, and destroy your work. Sheet
lead cemented to the wall will answer a good purpose
for a time, but the dampness will finally destroy the
cement and let the metal loose.
Battening out for lath and plaster is the best for
basement or damp stone walls, but that is the plasterer’s
work, and is rarely ever done except in private
residences.
Battening and canvasing is next best; nail your
battens up and down 18 inches apart. Have the
canvas stitched in sheets the right size to cover the
large blank spaces of the wall. Then stretch and
tack it on the battens, and give it a coat of glue and
alum size.
When dampness is caused by condensation the best
remedy is to remove the cause and dry the wall.
When paper is pasted on boards, it must crack,
when the lumber shrinks. If you paste cloth over the
cracks, it must crack, if the cracks open further than
the cloth will stretch. When you tack cloth on a
partition and size it, if the size goes through the
cloth and sticks it fast to the boards, it will be likely
to crack when the lumber shrinks. For a good job
I would advise that you first cover the partition with
paper tacked on, then when you size the cloth, it will
stick to the paper, and not to the boards. I have met
with uniform success in this way; because the boards
are left free to shrink and swell without breaking the
cloth or paper. I like to sew the cloth together with
a running seam in pieces large enough to cover all
broad spaces, turn the smooth side out, stretch well,
and fasten the edges only; drive the tacks an inch
from the edges of the cloth, so that you can fasten
them down smoothly with paste. When a man has
been unwise enough to put a board partition across
one end of an otherwise fine room, and is willing to
pay for his folly: first, take measurements of the
blank spaces, and sew together some fairly strong
unbleached muslin, stretch on frames, and give it a
coat of glue and alum size, and whiting; when dry,
carefully fit each piece in its place and tack it an
inch from the edges and fasten the edges down
smooth with strong flour paste. Tack only at the
edges, and if you are careful to butt edge the different
pieces over the doors, etc., you can make a nice
smooth job in this way. By using this method the
paste will not stick the cloth to the wall. Use tinned
tacks to prevent rust.
This is a job none of us like very well, but since
it must be done, it is worth while to be able to do
it to the best advantage. The first thing to look for
is good paper. To test the strength of the sand, rub
two pieces together, and if the sand don’t fly off, it
is good in that respect; next see if the paper is tough
and will not tear easily. Chalk the back of your
paper before you double it and it will not slip.
Don’t lose time using old, worn-out paper. New
paper will, of course, cut faster than old paper, and
the difference in the time gained by using sharp
paper will pay for the new paper twice over. Using
old dull paper is like trying to save money by using
an old stub brush. Better use up fifty cents’ worth
of paper than to fool away dollars’ worth of time
trying to save money by using old paper.
If you have old, hard paint to cut down, which
dry sandpaper will not touch, keep the work wet with
benzine, and you will be surprised to see how fast
the sandpaper will cut the paint. To put on benzine
use a small spring-bottomed can, such as is used for
oiling machinery. You can use any grade of sandpaper,
and it will not soak up or gum. No. 1 paper is the
best for this purpose. A good deal of time may be
lost where scrapers could be used to much better
advantage. A broad, flat scraper to shove endwise is
always in order, and a few narrow ones with various
shaped ends to fit in headings, moldings, etc., are
a great help.
This makes a nice finish for a painted or kalsomined
room. To make it look at its best, paint a
stripe as wide as your stencil in a pleasant contrast
to the paint on the room and put the stencil on that
in soft harmonizing colors.
To repaint a job which has commenced to scale,
without taking off all the old paint, is very uncertain
work, but if you have to try it, have it understood in
writing, or before witnesses, that it is done at the
owner’s risk. First scrape off the loose paint, then
go over the job with raw oil; put it on freely and let
it stand until dry; then scrape off all the paint loosened
by the oil, and coat up with strictly pure white
lead and oil. Avoid zinc, and mixtures of zinc, and
barytes, on jobs of this kind; because they are more
or less liable to crack, and pull off more of the old
paint. White lead and oil lightly tinted will hold
it if anything will. Use raw oil and a little good
japan.
Light weight colors which will not mix well with
water may be easily mixed to a stiff paste with molasses
or sirup, then mix in glue size for a binder
and thin with water.
Use a thin size of white glue in water, or a thin
starch paste. For a sign to stand weather, dissolve
white wax in turpentine by heat. Melt the wax in
a kettle, then take it outside and by degrees add sufficient
spirits of turpentine and make a thin size.
One ounce of wax to the quart of turps is about
right. Put it on warm with a brush.
Slake a little good, fresh lime in hot water and
mix a size with skim milk. Then strain through
cheese cloth. This size is, when dry, insoluble in
water and will hold lettering as long as the cloth
lasts. May be tinted.
