Abstract

PURPOSE:To form an imitation-stone-like or granite-like coating surface improved in weather resistance by the direct or prime coating of a base material and coating the resultant material with a specific liquid composition. CONSTITUTION:A colored silica sand is prepared by spraying a coloring composition obtained by dispersing a coloring pigment in a solution formed by dissolving or dispersing a weather-resistant resin in an organic solvent and/or water, on a silica sand with a particle size of 0.1-5mm, followed by drying. 20-300 pts.wt. colored silica sand. is dispersed in 50 pts.wt. (based on solid matter) liquid resin of aqueous emulsion or organic solvent base to obtain a liquid composition containing the colored silica sand. The liquid composition is applied to a direct- or prime-coated base material at a coating weight of 1,000-4,000 g/m<2>. Then, the colored silica sand on the coated surface is pressed by a plastic roller wet with a solvent or water to level the unevenness of the coated surface.
