LeakSeal Spray

LeakSeal Spray

Repair and prevent leaks on a wide range of demanding surfaces with Rust-Oleum LeakSeal Spray. This rubberized coating seals cracks, fills small holes and provides firm-but-flexible protection against moisture and rust on surfaces that need it most.

It provides a watertight, weatherproof barrier that also protects the surface from rust. LeakSeal dries to a semi-smooth, firm finish that will not sag or drip, and can be top-coated with latex or oil based paints. Designed for use on metal, aluminum, galvanized metal, PVC, concrete, masonry, asphalt roofing materials, vinyl, fiberglass, and more. Not recommended for rubber surfaces or surfaces exposed to continuous water immersion.
