Rust-Oleum® 380 Non-Fibered asphalt emulsion coating is a premium, water-base protective coating for built-up asphalt roofing and concrete foundations. Asphalt emulsions are faster drying, low odor alternatives to solvent-base asphalt roof coatings. 380 non-fibered asphalt emulsion can be used as a base coat for reflective coatings or as a protective coating for new or existing composition roofs with smooth surfaces. 380 non-fibered asphalt emulsion can also be used for damp-proofing exterior below-grade foundations and walls.
