What Happens If Flex Seal Gets Wet?

Once dry, Flex Seal’s watertight, rubberized coating can withstand water, heavy rains, snow, and more. Flex Seal can be applied to a wet surface or moist environment in the event of an emergency. However, it will always adhere better to a clean, dry surface. To ensure its longevity, we recommend reapplying Flex Seal once the area is completely dry.
