摘要 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.
