Now it is easier than ever to provide high quality watertight seal that won't sag, drip or crack! Flex Seal seals out water, air and moisture; preventing rust and corrosion. Use it anywhere!

Great for basements, chimnets, foundations, gutters, RVs and autos. One can of Flex Seal treats approximately 2-12 square feet.
