DIRECTIONS

Read entire can. Wear face and eye protection, protective gloves, and clothing. Make sure the surface is clean, dry, and free of grease, oil, and dirt. Shake well. Spray 8” to 12” from surface, using an even, sweeping motion. Apply multiple, even coats until ALL cracks and holes have been filled.

IMPORTANT: Allow 24 to 48 hours to dry before applying another coat.

Let it dry completely. (It usually takes up to 24 to 48 hours to fully cure.)

*Use Flex Seal ONLY in a well-ventilated area. When using inside, prevent vapor build-up by opening doors and windows. Ensure fresh air entry during application and drying.

*Do not use near heat, sparks, pilot lights or other sources of ignition.

FLEX TIPS:

Spray a larger area than area where the leak is and feather the edges. For best results, apply multiple coats rather than one thick coat and use at can temperatures above 60ºF.Make sure Flex Seal has filled ALL cracks and holes and is FULLY CURED before testing product. If light can pass through, apply additional coats.
