RustOleum Leak Seal 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 and corrosion. LeakSeal dries to a semi-smooth finish that will not sag or drip, and can be top-coated with latex or oil-based paints. This product is designed for use on metal, aluminum, galvanized metal, PVC, concrete, masonry, asphalt roofing materials, vinyl siding, fiberglass, and more. SURFACE PREPARATION Remove all dirt and debris from the area to be coated. Wash area with a detergent and water solution, rinse with fresh water, and allow the surface to dry thoroughly. Remove any loose paint or previous coatings with a wire brush or sandpaper. Lightly sand glossy APPLICATION Use outdoors or in a well ventilated area such as an open garage. Apply when temperature is between 50°F and 90ºF (10-32ºC) and humidity is below 85% to ensure proper drying. Do not apply to surfaces, when heated, exceed 200ºF (93ºC). Avoid spraying in very windy and dusty conditions. Cover surrounding area to protect from spray mist. Shake can vigorously for one minute after the mixing ball begins to rattle. If mixing ball fails to rattle DO NOT STRIKE CAN. Contact Rust-Oleum. A test spray on cardboard is recommended to obtain feel for the spray pattern. Hold can 8-18” from the surface and spray in short even strokes. It is recommended to apply a light first coat. Apply a second heavier coat to ensure proper coverage. A thicker film can be achieved by moving the nozzle closer to the surface. Initial spray may have some foaming or bubbling, but will dissipate as the coating dries. For best results, apply 2 coats. Allow to dry 15-30 minutes between coats. LeakSeal can be top-coated with water-based or oil-based paints after 24 hours.
