Q: How do I apply Flex Seal®?
A: Protective clothing is recommended. Use only in a well-ventilated area. When using inside, prevent vapor buildup 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. When covering large areas indoors, eliminate ignition sources far from the point of use because vapors are heavier than air and may travel significant distances. When applying to large areas indoors, do not exceed use of 1/2 of a can before allowing one hour for the coating to dry and vapors to dissipate before using again. Shake well and spray using an even sweeping motion. Apply several even coats until ALL cracks and holes have been filled. Allow Flex Seal® to dry completely before applying the next coat. Fully cures in 24 hours. Spray a larger area than where the leak occurred and feather edges. Works best at can temperatures above 60∞F. Occasionally shake can throughout application.
Q: How much will one can of Flex Seal® cover?
A: Depending on number of coats and thickness, one large can will treat up to a 2 to 8 square feet area and one JUMBO can will treat up to 2 to 12 square feet or 40% more! We recommend you spray the area using an even sweeping motion, let it dry completely and recoat again. Several even coats are better than one coat and each time you recoat the surface you will continue to fill in any holes or cracks and the surface will be sealed.
Q: How do I apply Flex Seal®
Shake well and spray an even sweeping motion from a distance of 12 to 14 inches. Spray a larger area than just where leak has occurred and feather edges.
