ABSTRACT:
Fire retardant coatings for metal structural members are obtained by spraying onto the structural members settable plaster compositions which are air-containing pumpable aqueous slurries of plaster, clay prill aggregate, cellulose and glass fiber reinforcement and foaming agent. The specially prepared clay prill aggregate has a low aspect ratio of near unity and is an acceptable substitute for the exfoliated vermiculite aggregate of prior coating compositions.
