How to apply Rust-Oleum Leak Seal

Remove dirt and debris from area to be coated. Cover and mask off areas to avoid overspray, if necessary. Shake can vigorously for one minute after mixing ball begins to rattle. Shake often during use. A test spray on cardboard is recommended to obtain feel for spray pattern. Spray surface in short, even strokes.



Hold can 20 to 30cm from surface. It is recommended to apply a light first coat. The second coat can be applied heavier. Quicker build-up can be achieved by moving nozzle closer in to gap. Initial spray may have some foaming/bubbling on the surface, but will dissipate as coating dries. For best results, and dependent on gap size, apply at least two coats. Allow to dry 15-30 minutes before coats. Dries to the touch in two hours and cures in 24 hours.


Top-Coating Tip:
Based on 21°C and 50 percent relative humidity, can be top-coated with latex-based or oil-based paints after 24 hours. Cooler temperatures or higher humidity may increase dry times.

Clogging Tip:
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 it in a solvent such as mineral spirits. Do not stick a pin or other objects into the stem.

Clean-up Tip:
Wipe tip off before storing. Clean up wet or dry coating with mineral spirits.
