Paint types

Cement Paints: These include various types of paints in which cement is the main component responsible for the hardness and durability of the painted surface. They are available in dry, powder form. Cement paints are waterproof. It is important to apply cement paint on a rough surface rather than on a smooth surface as its adhesion strength is higher on a rough surface than on a smooth surface. It is economical compared to oil paint. They are suitable for painting fresh plasters with high alkalinity as cement paints are unlikely to be attacked by masonry surface alkalinity. It is not necessary to remove existing paint to apply new paint.
Oil paints: These are usually applied in three different layers with different textures. These are called primes, undercoats and finishing coats. Wall moisture affects the life of oil paint. Hence it should not be applied in wet weather. It is a general paint that is cheap, quite workable and has the characteristics of opacity, good appearance, durability and resistance to weathering.
Cellulose paints: These are prepared from nitro cotton, celluloid sheets, photographic films etc. Cellulose paints are hardened by evaporation of thinning agents. Surfaces painted with cellulose can be easily washed and cleaned. They are slightly more expensive than other paints.
Aluminum Paint: Finely ground aluminum suspended in either quick-drying spirit varnish or slow-drying oil varnish as required. As the spirit or oil evaporates, a thin film of aluminum forms on the surface. These paints create a better protective surface on steel and iron. They are insensitive to moisture and possess high electrical resistance. They have a good shape and are visible in the dark.

Emulsion Paints: These paints contain polyvinyl acetate, synthetic resin etc. It is easy to apply and lasts for a long time and can be easily cleaned with water. For a rough plastered surface, a thin coat of cement paint can be applied first to smooth the surface. It is important to have a sound level to get the paint.
Anti-corrosive paints: They consist of oil and strong driers. Pigments such as chromium oxide, lead or zinc chrome are taken and added to the paint after mixing with a small amount of very fine sand. They are cheap and last a long time. They are usually black in color.
