Flex Seal 14 oz Black - 2-Pack | Waterproof Rubber Spray-On Sealant for Gutters, Wood, RVs & Roofs

Protect Your Projects with Flex Seal

Flex Seal 14 oz Black comes in a convenient 2-pack, delivering a spray-on rubberized sealant that dries to a flexible, watertight coating. Designed to simplify quick fixes, it works on a range of surfaces—from gutters and wood to RVs, campers, roofs, skylights, and windows. The coating seeps into cracks and holes, forming a continuous barrier that moves with the surface rather than cracking or peeling over time.

When used as directed, this product offers a versatile solution for preventing leaks and protecting materials. The cured film remains pliable, resisting the stress of temperature changes and everyday wear. The coating can be painted after it dries, allowing you to blend repairs with your preferred color scheme while maintaining the protective seal you expect from a rubberized coating.
