It is an epoxy putty that can be used for coating EPS foam. It can be textured by using texture stamps. It runs at around $110.00 a gallon with a thickening powder at around $11.00. Which is way less expensive than having your haunt shut down by the fire marshall because you used cheap crap that burns easily. Smooth-On has a video on how it is used. Look on their YouTube channel for it.
