Distemper (Painting)
Appearance
Distemper is an early form of whitewash usually made from powdered chalk and size (a gelatinous substance). Alternatives to chalk also include the toxic substances lime and white lead.
Distempered surfaces can be easily marked and discoloured, and cannot be washed down, so distemper is best suited to temporary and interior decorartion.
