<p>A four-fluid and one-powder, coloring-type material for surface treatment composed of an aqueous emulsion of a polymer having hydroxyl or carboxyl groups, a granular siliceous material, a liquid treatment for a substrate, a liquid reinforcement for a substrate, and a colorant. The liquid treatment is a mixture mainly comprising a powdered siliceous material, a calcium-containing material comprising calcium hydroxide or calcium oxide, an organic acid or its salt having an acid dissociation constant of 3 to 5, and water. The liquid reinforcement is a mixture mainly comprising an aqueous solution of an alkali silicate and an organic acid or its salt having an acid dissociation constant of 3 to 5. The colorant which can form coatings excellent in smoothness, strength and water resistance on any substrate is a mixture mainly comprising the above reinforcement, a powdered siliceous material as a leveling agent and a pigment. Tack-free coatings can be formed in a short time and the workability in coating is excellent.</p> |
