<P>PROBLEM TO BE SOLVED: To provide a binder for a wall coating material of porous aggregate having high material adsorptivity without deterioration in applicability, a wall coating raw material, and a method for producing a wall coating material. <P>SOLUTION: The binder for caking porous aggregate through hydration comprises a re-emulsifiable powdered resin as a moisture-permeable binding base resin, a thickener, reinforcing fibers and a surfactant as a defoaming agent. The surfactant inhibits invasion of bubbles into a wall coating material during hydration and kneading. Thereby, it is made possible to increase the amount of the aggregate per unit volume, and material adsorptivity of the wall coating material is enhanced. <P>COPYRIGHT: (C)2012,JPO&INPIT |
