Abstract
Inorganic coating compositions with alkali silicate comprising a viscous aqueous suspension which is obtained by heating above 50.degree. C. the mixture comprising an aqueous 10-50 weight percent solution of alkali silicate and 5-300 weight percent (vs. the solid component in said 10-50 weight percent aqueous solution) of amorphous silica powder hardenable upon application of a hardener solution comprising a surface tension reducing agent and an aqueous solution of at least one compound selected from phosphoric acid, phosphates, chlorides, sulfates, nitrates, fluorosilicates and ammonium persulfate.
