Can Flex Seal be applied in the rain?
Flex Seal Spray is designed to create a strong, waterproof barrier when applied to clean, dry surfaces. This will give you the best adhesion, smoothest finish, and longest-lasting seal. However, if you’re in the middle of a storm and need to act fast, Flex Seal Spray can be applied in the rain to provide a temporary barrier. It sprays out as a thick liquid and begins to bond immediately, even while water is present. This makes Flex Seal Spray a helpful tool for temporarily fixing active leaks until more thorough repairs can be made.
Flexpert Tip: Once the rain clears and the area is dry, you should always reapply additional coats of Flex Seal Spray for full protection.
