Abstract

PROBLEM TO BE SOLVED: To prevent a header part from becoming unnecessarily thick, prevent the deterioration of an adhesive property of a decorative sheet layer, and prevent the occurrence of upward parting in the decorative sheet layer by windingly and adhesively fixing only a base layer of a waterproof decorative surface material to the header part of a concrete plate. SOLUTION: A waterproof decorative building material 1 is constituted by sticking a waterproof decorative surface material 3 to a surface of a concrete plate 2. Here, the surface material 3 is made by leaving a prescribed space part where a base layer 6 is exposed as it is to both side edges of the surface material 3 without forming a decorative layer 7 over the whole surface of the base layer 6. The space part where this base layer 6 is exposed as it is adhesively fixed by being rolled in a header part of the concrete plate 2. Therefore, a thickness of the header part can be reduced, and since the decorative layer 7 of the surface material 3 is not rolled in a bending shape in the header part, the deterioration of an adhesive property of the surface material 3 and the occurrence of upward parting in the surface material 3 can be prevented.
