Can you spray Flex Seal on a wet surface?

Flex Seal is a versatile solution for sealing leaks, cracks, and holes. One of the biggest questions people have is whether it can be applied to a wet surface. If you’re in an emergency situation, Flex Seal can be applied on a wet surface or in a moist environment. However, it will always adhere better to a clean, dry surface. To ensure its longevity, if you do have to apply Flex Seal in wet conditions, be sure to reapply the product once the surface is completely dry to help maximize its effectiveness.
