Yes, specific products like Flex Shot and Flex Tape are designed to be applied to wet surfaces and can even work underwater to stop leaks instantly.
What is your return policy for opened products?
We offer a 30-day money-back guarantee. If you are not satisfied with the performance of the product, you can return the remaining portion for a full refund, minus shipping costs.
How long will my order take to arrive?
Standard shipping typically takes 3 to 7 business days within the continental United States. Expedited shipping options are available at checkout.
Is Flex Seal safe for use around plants and animals?
Once fully cured, Flex Seal is non-toxic and safe for use around plants and animals. However, we do not recommend using it for internal applications in drinking water containers.
Can I paint over Flex Seal once it has dried?
Flex Seal Liquid and Flex Paste can be painted over once fully cured. For Flex Seal Spray, we recommend using it as a final coat as some paints may not adhere properly to its rubberized surface.
