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.

CLEANING SILVER, BRASS OR COPPER.

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.

WHY DO WALL PAPERS CRACK?

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 FOR WHITEWASH.

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.

TO CLEAN BRICK.

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.

TO CLEAN TARNISHED ZINC.

Mix 1 part sulphuric acid with 12 parts water and rub the zinc with

it with a rag, then rinse with clear water.

TO GILD ON WOOD.

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.

STIR YOUR PAINT.

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.

TO MAKE CHERRY STAIN.

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.

VARNISH STAINS.

These often come very handy to the painter, not only in toning up

new wood, but in renewing the freshness of old work.

MAHOGANY VARNISH STAIN.

Spirits 1 gallon, gum sandarac 1 pound, shellac ½ pound, venice

turpentine 2 ounces, dragon’s blood 4 ounces.

WALNUT VARNISH STAIN.

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.)

MAHOGANY VARNISH STAIN.

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.

TO MAKE NEW OAK LOOK OLD.

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.

DARK STAIN FOR OAK.

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.

ANOTHER.

Apply with a brush, strong aqua ammonia until you get the desired

shade.

RED SAUNDERS STAIN.

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.

TO CHANGE THE COLOR OF WALNUT TO DARK MAHOGANY.

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.

NATURAL WOOD FINISHING.

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.

TO MAKE BLEACHED OR WHITE SHELLAC VARNISH.

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.

TO COLOR PUTTY.

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.

SPOTS ON PAINT.

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.

PORCELAIN FINISH.--CHINA GLOSS.--GLOSS FINISH.

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.

ANOTHER WAY.

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.
