 is an easy to use, rubberized 
protective utility coating designed to fill and seal leaks and

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,

..PRODUCT 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.  
..PRODUCT APPLICATION (cont.)    . 
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.  
DRY & RECOAT  
Dry and recoat times are based on 70ºF and 50% relative 
humidity. Allow more time at cooler temperatures. Dries to the 
touch in 20-30 minutes, to handle in 45-60 minutes, and can 
be re-coated with itself in 20-30 minutes. Allow 24 hours for 
full cure.  
CLEAN-UP 
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.
