Overview

Meet the Flex Seal 14 oz Blue, a waterproof rubber spray-on sealant designed to help you tackle leaks quickly and with minimal disruption. This versatile coating is formulated to seep into cracks and holes and dries to a watertight, flexible layer. Once dry, it can be painted any color to blend with surroundings, making it a practical option for a range of projects.

How it works

The formula penetrates small imperfections and expands into a pliable rubberized film that stays flexible over time. It resists drying out, cracking, or peeling when exposed to temperature changes, helping you maintain a durable barrier through seasons.

  • Seeps into cracks and holes and dries to a watertight, flexible coating.
  • Stays flexible and pliable; lasts for years of use with proper application.
  • Paintable after drying, allowing you to match or customize the finish.

Best uses and benefits

Transform and protect a wide range of surfaces and projects. It’s suitable for gutters, wood, RVs, campers, roof repairs, skylights, windows, and more, and it works on both wet and dry surfaces. The coating resists seasonal movement without sagging in heat or cracking in cold weather, providing ongoing protection where you need it most.

  • Protects surfaces from corrosion and weather exposure on wet or dry substrates.
  • Excellent for household repairs and hobby projects, offering a quick, durable seal.
  • Ideal for outdoor and travel settings like gutters, roofs, and RVs due to its transferable, flexible film.
