PRODUCT APPLICATION 
SURFACE PREPARATION 
All surfaces must be clean and free from dirt, grease, oil, 
mold, algae, loose granules, loose paint, rust, excess chalk 
and other foreign matter which could prevent proper 
adhesion. For quick and easy cleaning use Rust-Oleum Roof 
Patch Cleaner & Primer. Simply spray the product, wait 15-
30 seconds and then wipe it off and then immediately apply 
the Triple Thick Roof Patch & Sealer. The cleaner primer 
leaves behind an adhesions promoter which helps create 
strong adhesion to typically slick roofing substrates such as 
single ply membranes, previously coated roofs, metal and 
more.

WARNING! If you scrape, sand or remove old paint, you may 
release lead dust. LEAD IS TOXIC. EXPOSURE TO LEAD 
DUST CAN CAUSE SERIOUS ILLNESS, SUCH AS BRAIN 
DAMAGE, ESPECIALLY IN CHILDREN. PREGNANT 
WOMEN SHOULD ALSO AVOID EXPOSURE. Wear a 
NIOSH-Approved respirator to control lead exposure. Clean 
up carefully with a HEPA vacuum and a wet mop. Before you 
start, find out how to protect yourself and your family by 
contacting the National Lead Information Hotline at 1-800-
424-LEAD or log on to www.epa.gov/lead. 
APPLICATION 
Use outdoors or in a well ventilated area. Use when 
temperature is between 40-120°F (10-48°C) and humidity is 
below 85% to ensure proper drying. 
Shake can vigorously for one minute after mixing ball begins 
to rattle. Shake often during use. If mixing ball fails to rattle 
DO NOT STRIKE CAN. Contact Rust-Oleum. Hold can 
upright, and press applicator tip to spray material onto 
cleaned surface. Generally, a distance of 8-12” from the 
surface. Apply short, even strokes. For best results creating a 
heavy- build seal do not push the application button all the 
way down. This will slow the rate of spray and allow for a 
heavier build repair. 
DRY & RECOAT TIMES 
Dry and recoat times are based on 70ºF (21°C) and 50% 
relative humidity. Dry times increase at cooler temperatures. 
Dries to the touch to touch in 1-2 minutes. Recoat or topcoat 
in 10 minutes. Full waterproofing will occur after 1 hour and 
full cure in 24 hours. Can be top-coated with acrylic or solvent 
based roof coatings. 
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 it in a solvent such as mineral spirits. 
Do not stick a pin or other objects into the stem. 
CLEAN-UP 
Wipe tip off before storing. Clean up wet or dry coating with 
Xylene or mineral spirits. Throw away empty can in trash pick-
up. Do not burn or place in home trash compactor.
