Rust-Oleum LeakSeal is an easy-to-use, rubberised 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.

LeakSeal dries to a semi-smooth, firm finish that will not sag or drip, and can be top-coated with water-based or oil-based paints after 24 hours.

Practical Consumption

Practical coverage depends on many factors such as porosity and roughness of the substrate, size of the leakage and material losses during application.

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 surfaces. Wipe the sanded surface clean when finished. Test previous coated material for compatibility before use. A test spray on cardboard is recommended to obtain feel for spray pattern. Spray surface in short, even strokes. Hold can 8-18" 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.

Application Conditions

Use outdoors or in a well-ventilated area such as an open garage. Apply when temperature is between 50ºF 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 aerosol vigorously for one minute after the mixing ball begins to rattle. If mixing ball fails to rattle DO NOT STRIKE CAN. Contact Rust-Oleum for technical support. A test spray on cardboard is recommended to obtain feel for the spray pattern. Hold the aerosol 8-18” (20 - 45 centimetre) 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.

Remarks

• If the valve clogs, twist and pull off spray tip and rinse in a solvent such as mineral spirits. Do not insert any object into can valve opening.
• Wipe off tip when finished.
• Clean-up wet paint with xylene or mineral spirits. Properly discard empty container.
• Do not burn or place in home trash compactor.
