About this item

Rust-Oleum LeakSeal is an easy-to-use, rubberized protective utility coating designed to fill and seal leaks and cracks.


Rust-Oleum LeakSeal provides a water-tight, flexible seal that prevents moisture penetration, rust and corrosion. 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.


  • For Use On: Metal, aluminum, galvanized metal, PVC, concrete, masonry, asphalt roofing materials, vinyl siding, fiberglass, and more
  • Painting Conditions: Use outdoors or in a well ventilated area. Use when temperature is above 50°F and humidity is below 85% to ensure proper drying. Avoid spraying in windy, gusty conditions
  • Surface Preparation: Remove dirt and debris from area to be coated. Cover and mask off areas to avoid overspray if necessary
  • Application: Shake can vigorously for one minute after mixing ball begins to rattle. Shake often during use and spray surface in short even strokes. Hold can 8"-18" from surface. For best results apply at least 2 coats. Allow 15-30 minutes between coats. LeakSeal dries to the touch in 2 hours and cures in 24 hours
  • Top-Coating: LeakSeal can be top-coated with latex or oil-based paints after 24 hours. Cooler temperatures or higher humidity may increase dry times
  • Clogging: After use, turn can upside down and press spray nozzle until spray is clear to prevent clogging. If valve clogs, twist and pull off spray tip and rinse with a solvent such as mineral spirits. Do not stick a pin or other objects into the stem
  • Clean-Up: Wipe tip off before storing
  • Uses: Great for gutters, roofs, flashing, ductwork, PVC, masonry, concrete, downspouts, shingles, sheds, metal buildings, vent pipes, boats and more
  • Value Pack Includes: Two 15oz LeakSeal cans
