KOOL SEAL
Frequently asked questions
Common questions about KOOL SEAL from 3G Electric.
What types of roofing substrates are KOOL SEAL sealants compatible with?
KOOL SEAL sealants are formulated for use on asphalt, modified bitumen, metal, and concrete roofing surfaces. They adhere to aged built-up roofs (BUR) and can be applied over existing coatings if the surface is clean and dry. For best results, check the specific product data sheet for substrate compatibility and surface preparation requirements.
What is the typical application method for KOOL SEAL roofing sealants in pails?
KOOL SEAL roofing sealants in 1-gallon pails are designed for application with a putty knife or trowel. The material is spread directly onto the surface to fill cracks, seal seams, or coat small areas. For larger repairs, a brush or roller may be used, but the product’s consistency is optimized for trowel application to achieve proper thickness and adhesion.
Are KOOL SEAL products suitable for use in hot climates or on roofs exposed to direct sunlight?
KOOL SEAL asphalt-based sealants are formulated to withstand UV exposure and temperature fluctuations typical of outdoor roofing environments. However, prolonged exposure to extreme heat may affect flexibility over time. The brand’s products are not specifically rated for high-temperature industrial processes; they are intended for standard roofing maintenance in ambient conditions.
What is the shelf life of KOOL SEAL roofing sealants stored in unopened pails?
Unopened KOOL SEAL pails typically have a shelf life of 12 to 24 months when stored in a cool, dry location away from direct sunlight and freezing temperatures. Once opened, the sealant should be used within the manufacturer’s recommended working time to prevent skinning or curing in the container. Always verify the expiration date printed on the pail.
Can KOOL SEAL sealants be applied over wet surfaces or during rain?
No. KOOL SEAL sealants require a dry, clean surface for proper adhesion. Application on wet surfaces or during precipitation will compromise the bond and may lead to premature failure. The substrate should be free of moisture, debris, and loose material. Allow at least 24 hours of dry weather after application for curing, depending on ambient humidity and temperature.
