Flex Seal Liquid Rubber Black


Availability: Out of stock


Flex seal liquid is a proprietary formulation that starts out as a thick liquid and dries to a super strong, flexible, watertight rubberized coating. Flex seal liquid can be brushed, rolled, dipped or poured to create a high performance protective rubber barrier that blocks out air, water and moisture on a variety of surfaces and objects. Once cured, flex seal liquid forms a durable, breathable, weatherproof, non-slip barrier that's resistant to rain, snow, sun, wind, hail, air, moisture, UV degradation, extreme temperatures and natural weathering.
