FOAMCOAT is a non-toxic, water based coating for styrofoam and polystyrene foam, as well as other surfaces. It provides a hard, durable finish that resists chipping and cracking, yet can be sanded smooth or carved to add detailing. FOAMCOAT can be used on a wide variety of surfaces including foam, primed wood, concrete block, primed fiberglass, paper maché, muslin and many other materials. FOAMCOAT is fully compatible with all Rosco paints used either as tints or as surface coatings. FOAMCOAT is inherently flame retardant and water resistant.
