Abstract
Sealing compositions and application methods for sealing and protecting asphalt roof shingles or other porous roofing and construction materials are described for eliminating algae, mold and mildew, increasing granular adhesion, providing additional UV protection and significantly increasing the wind resistance of the roof or other construction material. The sealing composition includes an acrylic polymer that has been modified by a silicone surfactant to alter its wetting properties so as to promote wicking of the sealer under asphalt shingles and at open edges to prevent curling and water infiltration. The method of applying the sealing composition promotes uniform distribution of the product on the surface of installed roofs as well as enhances bonding between individual shingles by improved penetration on and between shingle layers to increase adhesion area.
