Flex Seal Colors is the colorful way to coat, seal, and stop leaks fast. It has the same sealing power as the original Flex Seal, but now it's available in vibrant colors that can transform and protect virtually anything. Flex Seal is liquid rubber in a can! It sprays out as a thick liquid, seeps into cracks and holes and dries to a watertight, flexible rubberized coating that Stops Leaks Fast! Unaffected by weather. In extreme heat or cold, Flex Seal keeps its hold! Stays flexible and pliable while protecting surfaces from corrosion. Seals out water, last for years. It's like a handyman in a can!
  • Apply with the portable, easy-to-use, aerosol spray can
  • Unlike paint, its thick liquid dries to a watertight, flexible, rubberized coating

  • Stops leaks while remaining completely flexible - apply on wet or dry surfaces

  • Perfect for all of your home repairs - transform and protect virtually everything
  • Ideal for arts and crafts, projects, and hobbies - once completely dry, it can be painted any color
  • Apply on wet or dry surfaces
  • Last for years and will not sag or drip in summer heat & will not crack or peel in winter cold
