Does Flex Shot expand?

Flex Shot does not expand in the way that spray foam products do, but it will expand and contract depending on temperature and humidity. This flexibility ensures the product will maintain a watertight seal, without cracking or shrinking. Flex Shot’s thick, rubberized texture fills gaps, cracks and holes with ease, making it a great choice for indoor and outdoor projects.
