Flexible liquid rubber coating you can apply in minutes

Flex Seal Liquid is liquid rubber in a can that you can brush, roll, dip, or pour on. It dries to a flexible film that seals out water, air and moisture while allowing surface movement. The result is a durable protective layer you can rely on for a range of projects.

Where this coating shines

Built to handle exterior and interior needs, it works well on roofs, basements, RVs, campers, trailers, and marine surfaces. It adheres to EPDM membranes and masonry, forming a breathable coating that remains flexible as conditions change.

  • Watertight, flexible coating that blocks water and moisture
  • Smooth, fast coverage that dries to a pliable film
  • UV resistant to help protect surfaces from sun exposure
  • Rust and corrosion prevention with chemical resistance

Real‑world use cases

Imagine sealing a leaky roof seam after a storm, stopping moisture creeping along a basement joint, or protecting a vent flashing on a trailer. Users often notice quick coverage and a surface that's ready for use again in hours.

How to apply for best results

Prepare the surface, shake well, and apply using your preferred method—brush for precision, roll for larger areas, dip for components, or pour for hard‑to‑reach spots. Apply in thin, even coats and allow to cure between passes.

  • Roof repairs, basements, exterior masonry
  • RVs, campers, trailers, and marine surfaces
  • EPDM membranes and other common substrates

Think of Flex Seal Liquid as a versatile, protective coating option when you want a barrier that stays flexible, blocks water, and stands up to environmental stresses. It’s a practical choice for DIY projects where a quick, dependable seal is helpful.
