Fast, Flexible Waterproofing That Travels With Your Project

Flex Seal 14 oz black delivers a fast, flexible waterproofing solution. The spray coats a rubberized film that seeps into cracks and patches leaks with ease. When it dries, it forms a dark, durable layer you can paint to blend with your surface.

Key Benefits at a Glance

  • Coats, seals, and protects quickly, with a finish you can paint after curing.
  • Seeps into gaps and holes to form a watertight, rubberized film that stays pliable for years.
  • Versatile for crafts, repairs, and DIY projects across many materials.
  • Protects surfaces from corrosion and works on wet or dry substrates.
  • Resists sagging in heat and cracking in cold, helping maintain adhesion over time.

Practical Use Scenarios

  • Gutters and downspouts to stop leaks around joints and seams.
  • Roofs, skylights, and windows to block water intrusion and drafts.
  • Wood, metal, vinyl, and other common surfaces in homes, RVs, or campers.
  • Arts and crafts projects that benefit from a durable, flexible sealant coating.

Flex Seal works on damp or dry surfaces, offering a straightforward way to protect against moisture and corrosion. The dark spray leaves a rubbery film that remains flexible as temperatures change. Real-world results can vary by surface and application, but many projects show notable protection after application.
