Surface must be clean and free of all dust, rust, residues, foreign matter, and all contaminants (chalk, grease, wax, etc.) that may cause loss of adhesion. Remove rust and scale from metal by wire brushing. Sweep area thoroughly to remove all dust, dirt, and other foreign matter that would interfere with a good bond. Scrub accumulated residue on low areas with detergent and rinse thoroughly. Surface must be dry and frost-free. Sealant adhesion should be tested on each different substrate prior to use. To test adhesion, apply sealant and allow to cure thoroughly. Then, pull one end to test adhesion strength.
Repair cracks, breaks, tears, and holes by applying 1/8″ to 1/2″ thick with a trowel or putty knife. Thicker application results in better performance and longer sealant life. Sealant can be applied over old silicone coating or sealant which has cured. Work the sealant into the damaged area and spread it 2” to 4” beyond, feathering the edges. Check to see that no voids have been left in patched areas. If so, apply more sealant and allow to set up before coating. NovaPatch is tack-free in about 1 hour and fully cured in about 48 hours (dependent on weather conditions, such as temperature and humidity).
Clean hands with waterless hand cleaner. Equipment may be cleaned before sealant cures with mineral spirits.
Not recommended for application at temperatures below 10°F or if rain is expected within 1 hour of application. DO NOT THIN. Keep containers covered and sealed. Material left exposed to the atmosphere may begin to cure and form a skin on the surface. If this occurs, remove the skin and use the rest. DO NOT MIX PRODUCT.
