Montana Granit Effect Spray is a water-based special effect spray paint with fine plastic particles for a deceivingly realistic granite effect. Apply on many different surfaces such as paper, cardboard, primed canvas, wood, glass, metal, ceramics, stone, polystyrene and other materials. It is very high covering. For best results, prime your surface, particularly when painting a light color on a dark surface. Can be top-coated once thoroughly dry.
