Designed to help block out water, air and moisture, Flex Seal MAX creates a tough protective layer that holds up against the elements and stays flexible over time. Use it on a variety of surfaces and projects, from quick household repairs to larger outdoor jobs. Simply spray to coat and seal, then let it cure for a strong, long-lasting seal that helps keep water out and protection in.
