Abstract

A coating composition includes water, a plurality of flakes having a maximum dimension less than 0.05 inches, a plurality of inorganic fibers, a thixotropic suspending agent that is insoluble in water, and a resin. Decorative coating on a concrete substrate is also provided.

First claim

What is claimed is:

1. A coated substrate comprising:
a substrate;
a decorative layer disposed over the substrate, the decorative layer including:
a resin;
a plurality of flakes having a maximum dimension less than 0.05 inches dispersed within the resin; and
a plurality of inorganic fibers dispersed within the resin wherein the decorative layer is not over-coated with any other resinous layer and wherein the decorative layer is formed by applying a coating composition to the substrate, the coating composition comprising:

a plurality of flakes present in an amount of 10 to 40 weight percent, the plurality of flakes having a maximum dimension less than 0.05 inches;
a plurality of inorganic fibers present in an amount from about 0.5 to 5 weight percent;
a thixotropic suspending agent present in an amount from about 0.2 to 4 weight percent, the thixotropic suspending agent being insoluble in water; and
a resin present in an amount from 10 to 25 weight percent with the balance of the coating composition being water.

2. The coated substrate of claim 1 wherein the plurality of flakes includes colored flakes.

3. The coated substrate of claim 1 wherein the plurality of flakes includes particles having an aspect ratio greater than 10.

4. The coated substrate of claim 1 wherein the thixotropic suspending agent includes magnesium silicate.

5. The coated substrate of claim 1 wherein the thixotropic suspending agent includes needle-shaped particles having a length from about 1 to 5 microns and a surface area from about 100 to 500 m 2 /gram.

6. The coated substrate of claim 1 wherein the resin includes at least one acrylic resin.

7. The coated substrate of claim 1 wherein the decorative layer has a thickness from about 0.01 inches to about 0.2 inches.
