Surface coatings and methods

Abstract

Provided herein include methods and compositions pertaining to coatings, such as paints, for covering a substrate. In some aspects and embodiments the coatings may include a heat reflective metal oxide pigment that, applied to an external surface of a building (or is applied on a substrate used for an external surface of a building such as an architectural metal panel, EIFS or as a stucco top coat) reduces the energy consumption in the building. In other aspects and embodiments, provided are textured coatings having a texturing material; for example, methods and compositions are provided pertaining to textured coatings that can be applied robotically or in an automated fashion. In various aspects and embodiments, textured coatings are provided that include a texturing material and a heat reflective metal oxide pigment. In some aspects and embodiments coatings that include pumice texturing materials (for example pumice having particle sizes of greater than 150 microns) are provided.
