Distempers are the cheaper variety of paints in which chalk is used as base and water is used as a carrier.
The emulsifying agent which is commonly used is glue or casein. Distempers are available in powder They are to be mixed with hot water before use.
The surface to be distempered should be thoroughly rubbed and cleaned. The cracks, if any should be filled by lime putty. The surface should be kept dry for about two months before applying distemper. Thus a primary coat is applied and is allowed to dry. Distemper is usually applied in two coats.
