(57) [Summary] [PROBLEMS] To provide a coating material for building finish and a panel for building finish using volcanic ash white sand, and a method for manufacturing these. SOLUTION: The raw unprocessed dry shirasu A having a function of generating active oxygen species / free radicals is used as a raw material, and the dry shirasu A is 50 to 65% and the binder B is 30 to 4%. 0%, 3-10% clay material C, 5% shirasu balloon D 10%, the adhesive reinforcing agent E is 0.08 to 2%, the coloring pigment F is 0.1 to 3%, and the sasa G is 1 to 5%. Further, an appropriate amount of water is added to the coating material 1 for architectural finish and kneaded, and applied on a base such as a gypsum board, a veneer board, a concrete board, a water-resistant plywood for mortar, an asbestos board, and the like, and a surface finishing process by various designs The construction finish panel is constituted by performing the above. |
