About This Product
Fast Roof Leak Repair and Sealing
Rust-Oleum® Triple Thick Roof Patch & Sealer patches and repairs roofing surfaces to stop leaks in minutes. The high-build acrylic formula creates a watertight, flexible seal that helps prevent moisture penetration and corrosion for long-lasting roof repairs.
Triple-Thick High-Build Acrylic Formula
The coating is three times thicker than Rust-Oleum LeakSeal® aerosol products, allowing it to build a substantial protective layer over damaged roofing areas. Its highly UV-resistant formulation is designed to withstand exterior exposure while maintaining a flexible seal.
Compatible Roofing Materials
Triple Thick Roof Patch & Sealer can be applied to metal, aluminum, Kynar®, concrete, modified bitumen, gutters, single-ply membranes, asphalt, shingles, and previously coated surfaces. It should not be applied over silicone coatings.
Roof Repair Coverage and Surface Preparation
Each 13 oz. can covers approximately 2.5–5 sq. ft., depending on the application. For the best and longest-lasting results, Rust-Oleum recommends preparing the repair area with Rust-Oleum Roof Patch Cleaner & Primer before applying the sealer.
