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