Flex Seal is a rubberized sealant spray coating that sprays out as a liquid, seeps into cracks and holes, and dries to a watertight, flexible coating. It stops leaks fast and is ideal for sealing and protecting surfaces throughout your home and outdoor structures. Whether you're dealing with roof leaks, gutter damage, foundation cracks, or weatherproofing needs, Flex Seal provides a durable, flexible solution that adapts to temperature changes and prevents water infiltration.
This all-purpose aerosol sealant works on virtually any surface, including wood, metal, tile, concrete, masonry, fabric, glass, plastic, aluminum, and dry wall. Once fully cured, the flexible rubberized coating can be painted over to match surrounding surfaces, making it both functional and cosmetically seamless.
Features and Benefits
- Quick Application: Simply shake, aim, and spray to start sealing in seconds with easy-to-use aerosol technology.
- Watertight Flexible Coating: Dries to a thick, flexible rubberized coating that seals out water and remains pliable in extreme heat or cold.
- Long-Lasting Protection: Stays flexible and won't sag in summer heat or crack and peel in winter cold, providing years of reliable protection against corrosion and rust.
- Versatile Coverage: Covers fast with just one pass and works on roofs, gutters, PVC pipes, RVs, campers, A/C units, chimneys, windowsills, and foundation cracks.
- Paintable Surface: Once fully cured and dry, the coating can be painted any color to blend with surrounding surfaces.
- Multiple Surface Compatibility: Applies on both wet and dry surfaces across wood, metal, concrete, masonry, tile, plastic, glass, and more.

Birdbath Repair
Don't know if Flex Seal is going to hold, but I used it to seal and strengthen a birdbath. Seems to coat well and give the birdbath a little glue to hold it together.
For the Birds
I used Flex Seal to coat the bowl on my ancient concrete birdbath. Not only did it stop ALL the leakage, but it provided a sparkling new white surface! The birds love it too!
