Abstract: An elastomeric roof coating and method of forming the roof coating are provided. The roof coating is formed from oil-based paint which is optionally treated to remove at least a portion of the solvents contained in the paint, and further includes emulsifying the oil-based paint, followed by the addition of varying amounts of water-based paint, a virgin latex polymer, and a plasticizer. Where white or light colored paints are used in the roof coating, the coating provides good reflective properties when applied to a roof surface.

Abstract: A composite roofing overlay containing paint waste is provided for use on a roof surface. The composite roofing overlay includes a bedding cement containing water-based paint waste and sand, a porous fabric embedded in the bedding cement, and at least one primer coat over the porous fabric and bedding cement. The composite roofing overlay may be used in combination with an overlying waterproof roofing membrane to provide an effective waterproof seal to new or existing roof structures.

Abstract: A composite roofing overlay containing paint waste is provided for use on a roof surface. The composite roofing overlay includes a bedding cement containing water-based paint waste and crushed recycled glass, a porous fabric embedded in the bedding cement, and at least one primer coat over the porous fabric and bedding cement. The composite roofing overlay may be used in combination with an overlying waterproof roofing membrane to provide an effective waterproof seal to new or existing roof structures.

Abstract: A method of treating oil-based paint waste is provided which includes removing at least a portion of the solvent contained in the paint waste and emulsifying the paint waste to form a paint waste residue. The paint waste residue can be combined with varying amounts of water-based paint waste, emulsifiers, a virgin latex polymer, and a plasticizer to form various roofing products including an elastomeric sealer, a primer, and elastomeric caulk. A bedding cement is also provided which includes water-based paint, sand, and an optional plasticizer. The roofing products may be used in combination to form a strong, water-resistant roofing composite overlay for new or existing roof structures.
