[54] COMPOSITION COMPRISING SUPERABSORBENT POLYMER
[57] Abstract: Disclosed is a composition (e.g., a texture composition) comprising, consisting of, or consisting essentially of calcium carbonate and superabsorbent polymer that can absorb at least about 50 times its mass and having a particle size of about 250 microns or less, wherein the composition is substantially free of a setting-type cementitious material. In some embodiments, cellulosic thickener content is reduced or eliminated from the texture composition. Also disclosed is a method of finishing a substrate comprising applying to the surface a wet composition comprising, consisting of, or consisting essentially of calcium carbonate and superabsorbent polymer that can absorb at least about 50 times its mass and having a particle size of about 250 microns or less, wherein the composition is substantially free of a setting-type cementitious material, and drying the composition on the substrate.
