PROBLEM TO BE SOLVED: To obtain the subject composition for use in wall surface decoration, freed from such drawbacks as to be cold in finish feeling, heavy to carry during thick coating operation, and low in thermal insulation, by mixing a specific foam with silica sand in specified proportions. SOLUTION: This composition is a granular product pref. <=1,200μm in particle size, obtained by mixing (A) 50-100 wt.% of a glass-clay mineral-based lightweight foam with (B) 0-50 wt.% of silica sand. In this composition, the content of the granules <=180μm in size is set at 0-20 wt.%. It is recommended that the component A to be used is e.g. a granular ultra-lightweight aggregate afforded for the purpose of recycling discarded waste glass.
