PMMA Roof Coatings
Paracoat roof coatings are designed to help protect existing smooth and granule-surfaced roof systems from the effects of weathering and and potential exposure to chemicals.* Paracoat, when applied in a reinforced application using Pro Fleece, can help to protect existing roof systems from the effects of ponding water. Paracoat should not be applied over roof systems applied in solvent-based adhesives unless the membrane/adhesive system is fully cured.
