Flex Seal's Flex Paste forms an incredibly thick, yet mouldable rubberized shield that seals out water, air and moisture. Use it to patch, plug and seal almost any surface, filling gaps and cracks up to 3 inches thick before it dries into a watertight, flexible rubberized coating. Flex Paste clings tenaciously to a vast array of surfaces - from wood and glass to concrete, metal, fabric and even underwater! Spread, shape and form this highly pliable paste exactly where you need it before it cures to form a seamless, airtight barrier that protects against leaks for years.
