Rust-Oleum LeakSeal White Rubber Sealant Spray provides a flexible, watertight coating that seals cracks and gaps on multiple surfaces to prevent moisture intrusion. This white spray dries to a firm, semi-smooth finish that resists sagging and dripping, allowing it to be top-coated with latex or oil-based paints. Ideal for use on metal, concrete, PVC, masonry, roofing materials, and more, it offers effective protection in both indoor and outdoor applications. Quick to apply and fast drying, it provides a dependable barrier against leaks and corrosion.

For best results, apply two coats with 15–30 minutes drying time between layers. LeakSeal can be top-coated after 24 hours once fully cured. The spray may initially foam or bubble, which dissipates as it dries to a durable, weatherproof finish. It is suitable for use on a wide range of surfaces including metal, galvanized metal, PVC, concrete, masonry, and vinyl siding. The product resists rust and corrosion while providing long-lasting waterproof protection in various environments. Proper surface preparation ensures optimal adhesion and performance.
