Can this spray work on a hairline crack in my basement floor? And will it be slippery if it gets wet?

Flex Seal Spray is a fantastic product to fill cracks and holes with a liquid that dries into a watertight, durable, flexible coating. Due to its essential sealing qualities, we do not suggest it for underfoot applications because surfaces may become slippery when wet.

Will it work to plug up a pin hole in a copper water pipe?

Yes, Flex Seal Spray will seal the hole, effectively blocking out water, air, and moisture. However, we do not recommend it for high-pressure applications. Message us with any other questions about our products. We're always happy to assist our customers!
