Distempers are applied directly over the plastered surface without any primer or putty. Distemper also functions as base coats for other superior paints and thereby helps in increasing the life of surface coats.
Distemper is available in two types
- Dry distemper ( water based paint)
- Oil bound distemper (OBD)
Dry Distemper is a water-based wall paint ingredient whose constituents are chalk lime, glue, and water. Distemper is brush applied and gives a better look than the traditional whitewash.

On application of a minimum of three coats, you get a smooth matt finish. The main feature of this paint is that it is washable.
The presence of drying oils in Oil bound distemper increase coverage area and enables the surface to dry within four hours.

Oil-bound distemper is preferred for interior applications on plaster, brick, and ordinary walls, and ceilings for industrial /residential uses. Oil-based distemper is more durable than dry distemper.

The plastic emulsions are available in the following types.
Vinyl matt emulsion
Gives a matt non-shiny finish that expertly covers small imperfections on the wall or ceiling.
