Rust-Oleum 985 Silicone Roof Coating is a high solids, 100% silicone-based roof coating that creates a durable, breathable, watertight and weatherproof barrier that resists natural weathering and reflects heat from the sun. This Roof Coating resists ultraviolet radiation and adapts to temperature extremes to provide long-term weathering protection and energy savings. It can be applied over spray applied polyurethane foam, aged single-ply roofs including PVC, EPDM, TPO, Hypalon, aged acrylic coatings, concrete, asphalt built-up roofs, granulated modified bitumen, metal, RV and trailer roofs and over existing silicone roof coats.
