Plaka is a casein paint, which is derived from milk proteins. It’s an all-purpose paint that dries quickly (within 12 to 24 hours) to a smooth, velvety matte surface that is extremely opaque, similar to gouache in appearance but will not re-wet. It adheres well to virtually any light or dark surface, including paper, wood, cardboard, leather, pottery, plaster, glass, plastic, and stone. Plaka is ideal for commercial art and window displays as well as transparencies, posters, interior and exterior decorations, crafts, and model-making. It is fade-proof and waterproof; however, paintings intended to be long-lasting should be coated with an air-dry lacquer. Stir Plaka before using. It may be diluted with water.
