Seal leaks fast with Flex Seal

Flex Seal 14 oz Brown 2-Pack delivers a quick, spray-on rubber coating that dries to a flexible, watertight seal. It seeps into cracks and holes, forming a durable layer that resists wear over years of exposure. The finish can be painted to match your project once dry, giving you a seamless look after application.

Why it stands out

This product creates a resilient barrier that remains flexible, so it stands up to temperature swings without sagging, cracking, or peeling. It’s designed to work on both wet and dry surfaces, making it a versatile choice for on-the-spot repairs and preventative protection around the home, workshop, or RV.

  • Seeps into cracks and holes to form a flexible seal.
  • Dries to a watertight, rubberized coating that stays pliable for years.
  • Paintable after drying for color-matched finishes.

Ideal uses and benefits

Use Flex Seal on a wide range of surfaces and projects where water resistance and durability matter. It’s particularly helpful for exterior gaps, leaks, and quick fixes that you want to last through seasons.

  • Gutters, wood, RVs, campers, roofs, skylights, and windows.
  • Arts & crafts, DIY projects, and hobbies that benefit from a waterproof seal.
  • Surface protection from corrosion and water intrusion on both wet or dry surfaces.
