Rust-Oleum Leakseal is an easy to use, rubberized protective utility coating designed to fill and seal leaks and cracks. It provides a water-tight, flexible seal that prevents moisture penetration, rust, and corrosion. Leak seal dries to a semi-smooth, firm finish that will not sag or drip, and can be top-coated with latex or oil based paints.
