Abstract:
1. A lightweight finish composition comprising: a) lightweight aggregate wetted out by the combination of an alkali metal phosphate (AMP) and an alkylolammonium salt of a polyfunctional polymer (ASPP) wherein the AMP is present in an amount of from about 0.05% to about 3% and the ASPP is present in an amount of from about 0.05% to about 3% by weight of the lightweight finish composition, b) a resin dispersion or emulsion, wherein the combination of the ASPP and the AMP provides stability to the lightweight finish composition by wetting out the lightweight aggregate such that three weeks after producing the lightweight finish composition, the viscosity as measured in paste units (PU) does not measure more than about 140 paste units.
