Summary: | PROBLEM TO BE SOLVED: To protect the surface of diatomaceous earth member capable of imparting excellent adhesiveness, abrasion resistance and water resistance without impairing moisture-conditioning property, deodorizing property or the like of diatomaceous earth and used for interior wall materials or the like for building by applying an inorganic aeration type water-repellent coating material comprising colloidal silica, silane-based water repellent or the like. SOLUTION: An inorganic aeration type water-repellent coating material containing (A) colloidal silica, (B) a silane-based water repellent such as sodium trimethylsilylsulfonate, (C) an aqueous resin emulsion such as an acrylic aqueous emulsion and (D) other inorganic substance such as quartz, preferably at a ratio of 1-20 wt.% component A, 10-30 pts.wt. component B based on both solid content total amount of the components A and C and 100-1,000 pts.wt. component D based on 100 pts.wt. total amount of both solid content of the components A and C and the component B is applied, preferably in an amount of >=100 g/m to the surface of a diatomaceous earth to protect the surface of diatomaceous earth based member. |
