Flex Seal Liquid Rubber Sealant Coating for Repair and Protection Black, 14 oz / 396 g

Flex Seal Liquid Rubber Sealant Coating is designed to help seal, protect, and repair a wide variety of surfaces. The thick liquid formula spreads smoothly and flows into cracks, gaps, and small holes to create a durable waterproof barrier once dry. Suitable for use on materials such as metal, wood, plastic, concrete, masonry, and more, it helps protect surfaces from moisture, air, and weather exposure. The coating dries to form a flexible rubberized layer that moves with the surface while maintaining a strong seal. Ideal for household repairs, maintenance projects, and outdoor applications, it can be applied with a brush, roller, or pouring method for easy coverage. Once cured, it provides long-lasting protection while helping extend the life of repaired areas. This versatile sealant offers a practical solution for sealing leaks and protecting surfaces from everyday wear and environmental conditions.
