Abstract
A coating composition. The composition includes particles of polystyrene foam in admixture with a latex resin binder. The admixture can be sprayed or otherwise coated on a roof or other surface and provides a durable, insulating and inexpensive substitute for other coating materials. The amount of latex binder, which is relatively expensive, is preferably kept to a minimum and the polystyrene foam particles may be derived from waste or low-cost foam polystyrene.
