Surface treatment method and agent
 The treatment agent is a four-liquid one-powder coloring type agent consisting of a polymeric water emulsion having hydroxyl groups and/or carboxyl groups; a silica-based granular material; a base treatment agent in the state of a liquid; a base reinforcing agent in the state of a liquid; and a coloring agent. The base treatment agent is a mixture generally comprised of a silica-based powder or granular material; a calcium-containing substance coontaining calcium hydroxide and/or a calcium oxide; organic acid and/or salt of organic acid having an acid dissociation exponent ranging from 3 to 5; and water. The base reinforcing agent is a mixture generally comprised of an aqueous solution of alkali silicate; and organic acid and/or salt of organic acid having an acid dissociation exponent ranging from 3 to 5. The coloring agent, which is capable of coating any type of base member with a smooth, strong film having great resistance to water damage, is a mixture generally comprised of the aforementioned base reinforcing agent, silica-based powder serving as a smoothing agent, and a pigment. The surface treatment agent can be applied easily and conveniently and is capable of forming a coating film that can be set to touch in a short period of time.
