Limestone masonry veneer, resurfacing and aesthetic overlay compositions, methods of making and methods of use

Abstract

A limestone based masonry veneer composition is described that may be molded, blown, sprayed, troweled, or otherwise applied to interior and exterior surfaces. The composition provides an aesthetic resurfacing, cladding and/or overlay coating. The composition is capable of being pigmented, textured, sculpted—or otherwise formed into an aesthetic, realistic, architecture, suitable as a stone veneer, an example of which is Blown Stone®, by Stone Coat®. Texturing or sculpting may occur about 1 hour and up to about 12 hours after applying the composition. The final composition is hydrophobic and breathes. Air carbonation allows the formation of a predominantly very pure calcium carbonate or limestone when fully cured, which prevents mold and algae growth and allows for autogenous healing with an increase in unit weight over time, ensuring an overall high compressive strength that endures over time.
