Abstract
A coating composition for thick coating prepared by adding an aggregate to a coating liquid containing 5 to 40% by weight as SiO.sub.2 of a coloidal silica and 3 to 40% by weight of dissolved and/or finely dispersed organic polymer, having an SiO.sub. 2 /M.sub.2 O mole ratio (in which M is a monovalent alkali metal atom) of at least 7, and having a viscosity lower than 100 c.p. at 20.degree. C when kept in the sealed state at 50.degree. C for 10 days. Said coating composition being especially suitable for coating of 1 - 20 kg/m.sup.2 in thickness and storable for a long period of time with an excellent stability, giving a cured coating having high water resistance, good weather resistance, high adhesive strength and no efflorescence in its surface.
