This Flex Seal rubberized sealant spray coating sprays out as a liquid, seeps into cracks and holes and dries to a watertight, flexible coating. It's an easy way to coat, seal and stop leaks fast. Once completely dry, it can be painted any color. Can be used on wet or dry surfaces. Stays flexible and pliable. Won't sag or drip in summer heat. Doesn't crack or peel in winter cold. Stops vibrations and deadens noise.
