Abstract: The improved insulative fireproof textured coating composition includes water in a substantial proportion as a vehicle, in which particulate silica flour or the like silica-containing refractory or particulate calcium carbonate or similar non-porous filler is dispersed in substantial proportion along with thermo-insulating, porous particulate filler selected from lava rock and slag cinder. Pollution-free alkali metal silicate binder and liquid organic suspending agent selected from starch, paraffin or halogenated paraffin suspended in a vehicle are also present. Inorganic coloring agent such as titanium dioxide or other pigment may be present in a minor concentration. The composition is simple to make up, inexpensive, easy to apply and highly effective, when dried on a surface, as a hard, durable, thermally insulative, non-polluting fireproof, termite proof, textured protective layer.

Abstract: The improved fireproof liquid coating composition of the present invention includes water in a substantial proportion as a base or vehicle, in which silica sand, fire clay or the like silica-containing material is dispersed, along with granular zinc oxide, a selected silicate binder and suspending agent such as calcium silicate or sodium silicate, and a minor concentration of a thermoplastic resin binder and suspensing agent, such as polyvinyl acetate.An alkali metal fluorosilicate can also be present, if desired, to help dry the composition when it is applied to a surface to be protected against fire, rain and other elements. Moreover, coloring agents, preferably selected inorganic oxides, can also be present to suitably color the composition. The composition is simple to make up, inexpensive, easy to apply and highly effective when dried on a surface as a hard fire protective durable layer.
