US 12,209,413 B2 · System and method for exposed aggregate architectural coating for existing concrete structures

Abstract

The invention involves an exposed aggregate architectural coating to be applied to existing concrete structures. The invention includes a method of preparing and roughening an existing concrete structure surface, mixing the components of the exposed aggregate architectural coating, applying the coating to the existing concrete structure, spreading the coating to a thickness of one-fourth of an inch or thinner, using a trowel, gauge rake, or other method to smoothen the coating, allowing the coating to cure, applying a surface retarder once the exposed aggregate architectural coating has stiffened, allowing the surface retarder to cure for twenty-four hours, and washing the surface with a pressure-washer to remove the surface retarder, then “acid-washing” the surface to remove residue and create a desired texture. The resulting applied exposed aggregate architectural coating will have an exposed aggregate finish that is durable and suitable for high vehicular and pedestrian traffic areas.

Dependent claims

A method for preparing and applying an exposed aggregate architectural coating, comprising:

preparing a first composition by combining sand with cement;
preparing a second composition by water with glue;
combining the first composition with the second composition to form an exposed aggregate architectural coating;
preparing a pre-existing cement structure to create a roughened surface having a concrete surface profile of three or greater;
and
applying the exposed aggregate architectural coating to the roughened surface of the pre-existing cement structure by evenly spreading the exposed aggregate architectural coating onto the roughened surface to create an even thickness of the exposed aggregate architectural coating, wherein the exposed aggregate architectural coating forms a thickness of up to three-fourth of an inch above the roughened surface, wherein combining the first composition with the second composition to form the exposed aggregate architectural coating occurs prior to applying the exposed aggregate architectural coating to the roughened surface of the pre-existing cement structure.
