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, papier mâché, muslin and many other materials. FoamCoat is fully compatible with all Rosco Scenic Paints used either as colorants or as surface coatings. FoamCoat is flame retardant and water resistant.
