Rust-Oleum ® Self-Leveling Sealant is a high-performance, single-component, moisture-curing, room-temperature vulcanizing (RTV) silicone sealant that cures to a low durometer finish. This sealant offers exceptional elongation and durability, maintaining flexibility and a low modulus to accommodate movement around fasteners and penetrations. It provides excellent unprimed adhesion to concrete, metals, and most construction substrates, as long as surfaces are clean, dry, and free of dust or frost. Self-Leveling Sealant is highly resistant to environmental factors, including UV exposure, ozone, extreme temperatures, rain and snow, ensuring long-term performance
