IFR Foamcoat™ provides a hard, durable finish for styrofoam, polystyrene and other scenic, prop or soft display surfaces. An ideal substitute for joint compound or plaster, it is water-based and non-toxic. It dries to a flexible, milky matte finish, and can be tinted or painted, sanded and carved. Items coated with Foamcoat™ can take plenty of abuse, making it great for set pieces and tours.
