Abstract: A method for producing a building material includes a first step of applying an undercoat paint onto a surface of an inorganic base material, curing the undercoat paint, and polishing the undercoat paint; and a second step of applying an enamel paint onto the undercoat paint and curing the enamel paint. The undercoat paint contains an undercoat-forming material and a filler. The enamel paint contains an enamel-forming material and a pigment. The enamel-forming material is a solvent-based resin. A content of the filler in the undercoat paint is 40% to 70% by mass in terms of solid content. A content of the pigment in the enamel paint is 1% to 50% by mass in terms of solid content.

Abstract: A method for producing a building material includes a first step of applying a first ultraviolet-curable paint onto an inorganic material containing a woody reinforcement and incompletely curing the first ultraviolet-curable paint, a second step of applying a second ultraviolet-curable paint and completely curing the second ultraviolet-curable paint, a third step of polishing the completely cured second ultraviolet-curable paint to smoothen a surface of the completely cured second ultraviolet-curable paint, and a fourth step of applying an enamel paint and curing the enamel paint. In the second step, the second ultraviolet-curable paint is applied while the first ultraviolet-curable paint is incompletely cured.

Abstract: A building material includes a base material, a first mirror coating formed on the surface of the base material, a second mirror coating formed on the surface of the first mirror coating, wherein the first mirror coating contains a filler and a first resin material, the pencil hardness of the first mirror coating is in the range of about 3H to about 8H, the second mirror coating contains at least a second resin material, and the pencil hardness of the second mirror coating is in the range of about B to about 2H.
