ABSTRACT OF THE DISCLOSURE This invention is a self-curable inorganic composition consisting of (A) an alkali silicate as a binder, (B) about 30 to about 300% by weight, based on the solids content of the binder (A), of a hardener composed of (i) 100 parts by weight of a compound selected from the group consisting of calcium sulfite and calcium thiosulfate, (ii) about 50 to about 300 parts by weight of calcium silicate, (iii) about 40 to about 300 parts by weight of zinc oxide, and (iv) 0 to about 150 parts by weight of an aluminum-con- taining inorganic compound selected from the group consisting of aluminum hydroxide, alumina and hydrated alumina, (C) 0 to about 20% by weight, based on the weight of the composition in the uncured state, of another additive selected from the group consisting of coloring agents, thickeners, water repellents, curing retarders, dispersants, defoamers, and levelling agents, and (D) 0 to about 80% by weight, based on the weight of the composition in the uncured state, of a filler, aggregate or reinforcing material. The composition has a suitable pot life and can form a coating of good adhesive strength in the absence of a primer on application to the surface of various substrates for example building materials.
