Flex Foam™ is the newest innovation to join the ever-growing Flex Seal Family of Products. This super thick foam sealant instantly expands to fill gaps, cracks, and holes to block out moisture, drafts, pests, and more.

"Ordinary foams are stiff and break apart, but Flex Foam is different," said Phil Swift, CEO and Spokesman for the Flex Seal Family of Products. "It stays flexible and moves with surfaces, so it holds on strong, even when walls and foundations shift."
