Abstract
A water-based coating composition is described herein. The composition includes an aqueous dispersion derived from an ethylenically unsaturated monomer and one or more organic solvents. The composition when applied to a substrate and allowed to dry provides a wet look to the substrate.
Claims21
A coating composition for a cementitious substrate, comprising:
- an aqueous dispersion comprising a polymer and an aqueous carrier, the polymer having a number average molecular weight greater than 5,000 and up to about 50,000, the polymer having a Tg of greater than 0° C., and the polymer derived from at least one ethylenically unsaturated monomer;
- and
- a combination of two or more organic solvents comprising:
- a first solvent having a boiling point between about 120° C. and 210° C.;
- and
- a second solvent having a boiling point between about 210° C. and 300° C.,
- wherein the polymer comprises about 40 to about 90 wt % of the total weight of the dispersion, not including the aqueous carrier, and the combination of the two or more organic solvents comprise about 10 to about 60 wt % of the coating composition based on the total weight of the dispersion, not including the aqueous carrier;
- and
- wherein the coating composition, when applied to the cementitious substrate and allowed to dry, provides a wet look.

A method of coating a cementitious substrate, comprising:
- applying on the cementitious substrate a coating composition comprising:
- an aqueous dispersion of a polymer and an aqueous carrier, the polymer having a number average molecular weight greater than 5,000 and up to about 50,000 and a Tg of greater than 0° C. and derived from at least one ethylenically unsaturated monomer;

- wherein the polymer comprises about 40 to about 90 wt % of the total weight of the dispersion, not including the aqueous carrier, and the combination of the two or more organic solvents comprise about 10 to about 60 wt % of the coating composition based on the total weight of the dispersion, not including the aqueous carrier;
- and
- allowing water to evaporate from the substrate to provide a coating with a wet look.

- and
- a second solvent having a boiling point between about 210° C. and 300° C.,
- wherein the latex polymer comprises about 40 to about 90 wt % of the total weight of the dispersion, not including the aqueous carrier, and the combination of the two or more organic solvents comprise about 10 to about 60 wt % of the coating composition based on the total weight of the dispersion, not including the aqueous carrier;
- and
- wherein the coating composition is devoid of a colorant or pigment, such that when the coating composition is applied to the cementitious substrate and allowed to dry, provides a clear wet look.
