Abstract:

A viscosity stable, stainable, wood textured aqueous latex caulking composition is disclosed in which wood particles have sorbed therein, water immiscible organic solvent providing a free-flowing, solvent-wet powder. An aqueous emulsion of film-forming resin particles is mixed in and an oily plasticizer for the resin particles is added to provide a T. sub. g below about -40. degree. C. unless the resin particles are internally plasticized. The proportion of wood particles, the solids content of the aqueous emulsion and the proportion of oily plasticizer or other thickener provides a viscous mass of gunable viscosity.
