Surface coatings and methods
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, as a stucco top coat or as a top coat for roofing tiles) 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 heat reflective coatings for concrete or clay tiles and methods of applying such are provided.
1. A method of applying a heat reflective coating to a concrete or clay tile, said method comprising spray applying a heat reflective coating to the surface of said concrete or clay tile; wherein said heat reflective coating comprises a heat reflective metal oxide pigment, an acrylic resin and a fluorinated resin system; and wherein the heat reflective metal oxide pigment comprises one or more pigments selected from the group consisting of a pigment having a corundum-hematite crystal lattice structure, a pigment having a spinel crystal lattice structure and a pigment having a nickel titanate rutile structure.
2. The method of claim 1 , wherein said acrylic resin is a quick set resin.
3. The method of claim 1 , wherein said coating further comprises a PVDF fluorinated resin system.
4. The method of claim 1 , wherein said coating further comprises a FEVE fluorinated resin system.
5. The method of claim 1 , wherein said coating is applied while the concrete or clay tile is wet (unhardened).
6. The method of claim 1 , wherein said coating is applied while the concrete or clay tile is dry (hardened).
7. The method of claim 1 , wherein said coating is applied while the concrete or clay tile is wet (unhardened) and wherein said concrete or clay tile is heated until said concrete or clay substrate and said coating dry (harden).
8. The method of claim 1 , wherein said coating is applied while said concrete or clay tile is wet (unhardened) and said method further comprises heating concrete or clay tile until said concrete or clay substrate and said coating dry (harden) and applying a second coat of said heat reflective coating to said concrete or clay tile.
9. The method of claim 1 wherein said heat reflective coating is applied at 3-5 mils dry film thickness.
10. The method of claim 1 , wherein the coating is applied in an automated factory system.
