PROBLEM TO BE SOLVED: To provide a coating composition being hardenable at ordinary temperature and having excellent properties even in a content of neutral inorganic matter of 70-90%, whereas current inorganic coatings require sodium silicate or cement to achieve a content of inorganic matter in film of 50% or higher, resulting in various problems associated with alkaline substances contained in the silicate and/or cement. SOLUTION: The composition is manufactured by blending an inorganic filler, a pigment, an epoxy resin, a silane coupling agent, etc. and a stabilizing agent, with an ion-exchanged water-diluted mixed solution of colloidal alumina and colloidal silica prepared by a specified method so as to obtain the major solution and mixing the major solution with a hardening solution consisting of an alkylmethoxysilane or an alkylethoxysilane mixed with a small amount of a water-soluble acrylic resin and then applied to be hardened at ordinary temperature in order to obtain a hardened film of a content of neutral inorganic matter of about 85% having excellent properties.
