WALL-COATING MATERIAL COMPOSITION FOR INTERIOR

PROBLEM TO BE SOLVED: To impart an excellent adsorptive decomposability of aldehydes to a wall-coating material for interior by compounding an aggregate, an adhesive and a chemical adsorbing agent for aldehydes in the composition. SOLUTION: As an aggregate, one or more selected among silica sand, wood flours, natural pumice, artificial aggregates and crushed stones can be used. As an adhesive, for example, a carboxymethyl cellulose sodium salt, methyl cellulose, natural gum and the like can be used. As a chemical adsorbing agent for aldehydes, at least one selected from among hydrazies, azoles and azines is preferable. Incorporation of the chemical adsorbing agent for aldehydes in an amount of at least 5 g relative to the amount of a wall-coating material composition for interior to be coated on 3.3 m2 of a wall surface brings about a substantially sufficient adsorptive decomposition effect of aldehydes. The aggregate, the adhesive and the chemical adsorbing agent for aldehydes, and if required, a tying material, a humidity-controllability-improving agent, a colorant, a soft texture-imparting material or the like are admixed to give a wall-coating composition for interior.
