A concrete floor: Add 1 quart of thinning liquid (1 part turpentine or mineral spirits to
2 parts of spar varnish) to each gallon of enamel. Apply body and final coats as
furnished in the container.
(20) Bituminous (coal tar) or asphalt coating. This coating is used extensively as
waterproofing, as roofing, and for protection of submerged and buried metal pipes and devices. It is
applied at reasonable cost and makes a substantial barrier against attack by moisture and oxygen.
Asphalt coating is available as an enamel, a cold-applied paint, and an emulsion. It is considered more
resistant to the elements than coal tar.
(21) Waterproofing paint. Masonry is porous and soaks up water, causing damp interior
walls, cracked plaster, and peeling wallpaper and paints. Silicone water-repellent paint will usually
prevent this problem. With a single application (spray or brush), you will be able to provide an invisible
water-repellent surface that will preserve the finish for 5 to 10 years. Oil-based and cement-based paints
can be applied over the application. Oil-based paints will destroy the breathing characteristics of the
(22) Swimming-pool paint. Rubber-based paint is popular for painting swimming pools and
other water-holding structures; however, water-mix cement-based and enamel paints with a water-
resisting varnish vehicle of synthetic resin are popular. Recent developments have led to the use of
epoxies, polyesters, and urethanes that have better resistance to water, chemicals, and abrasion than
conventional coatings; but they are more expensive.
(23) Fungicidal paint. Fungicidal paint is used to preserve wood and fabrics by preventing rot.
These paints are popular for foundation timbers, sills, fence posts, and farm buildings.
(24) Fire-retardant paint. Fire-retardant paint retards the spread of fire by a chemical action of
the contents that tends to smother the fire.
(25) Camouflage paint. Camouflage paint has a dull finish, does not fade, is easily applied, is
inexpensive, and covers in one coat. Camouflage paint is available in nine colors: light green, dark
green, sand, field drab, earth brown, earth yellow, loam, earth red, and olive drab.
(26) Traffic paint. A ready-mixed traffic paint is known as centerline, zone-marking, and
road-marking paint. It is available in white and yellow, and it is intended for application at a wide range
of temperatures to bituminous and concrete highways bearing heavy traffic. Another type of traffic
paint is one in which glass spheres are added when the paint is applied to the road surface. This
semipaste form of paint, available in various colors, is called a pigmented binder. The glass beads serve
as reflectors when automobile lights strike them at night.
(27) Whitewash. Whitewash is a lime paste mixed with water. The paint is inexpensive and
used for covering interior and exterior wood or masonry surfaces. You primarily use it on brick,
concrete, road or roadside obstructions (sidewalks, parking curbs, light posts), sheds, telephone poles,
and so forth Make lime paste by slaking quicklime in enough water to make a stiff paste and allowing it
to cure for several months. The mixing
