=104. Quantities.=—One pound of pure lead-and-oil paint will cover
from 2¾ to 3¼ square yards of wood for the first coat, and from 4½ to
6 square yards for each additional coat; on brickwork, it will cover
about 1½ and 2 square yards, respectively. Colored paint will cover
about one-third more surface than white paint.
Using prepared or ready-mixed paint, 1 gallon will cover from 250 to
300 square feet of wooden surface, two coats; for covering metallic
surfaces, 1 gallon will be sufficient for from 300 to 400 square
feet, one coat. The weight per gallon of pure mixed paints varies
considerably, but, on an average, may be taken at about 16 pounds.
Prepared shingle stains will cover about 200 square feet of surface per
gallon if applied with a brush; or, this quantity will be sufficient
for dipping about 500 shingles. Rough-sawed shingles will require about
50 per cent. more stain than smooth ones.
One pound of cold-water paint, for the first coat, will cover from 50
to 75 square feet of wood, according to the surface condition, and
about 40 square feet of brick and stone.
One gallon of liquid pigment filler, hard-oil finish, or varnish will
generally cover from 350 to 450 square feet of surface for the first
coat, according to the nature of the wood and the finish, and from 450
to 550 square feet for the second and subsequent coats. One pound of
paste wooden filler will cover about 40 square feet.
One gallon of varnish weighs from 8 to 9 pounds; turpentine, about 7
pounds; and boiled or raw linseed oil, about 7¾ pounds.
For puttying, about 5 pounds of putty will be sufficient for 100 square
yards of interior and exterior work.
For sizing, about ½ pound of glue is used to 1 gallon of water.
For mixing paints, the figures given in Table XIV represent the average
proportions of materials required for each 100 pounds of lead.
