Coats, seals, and protects

Sprays out as a liquid that seeps into holes and cracks, then dries to form a watertight, flexible, rubberized coating.

Helps protect against rust and corrosion

Great for auto repairs and restorations. Extends the life of vehicles by providing an added layer of protection.

Works indoors and outdoors

Won’t sag or drip in summer heat or crack and peel in winter. Lasts for years without cracking, peeling or losing any of its strength or sealing properties.

Apply to almost any surface

Use on: wood, metal, tile, concrete, masonry, fabric, glass, plastic, aluminum, drywall, and more.

Fully paintable

After repairs are done, simply paint the color of your choice for fixes that are virtually undetectable.

Made in the USA

Flex Seal spray is proudly made in America, using globally sourced products.

Make sure the surface is clean, dry, and free of grease, oil, and dirt.

Shake well. Spray 20cm to 30cm from surface, using an even, sweeping motion.

Apply multiple, even coats until ALL cracks and holes have been filled.

Let it dry completely. (It usually takes up to 24 to 48 hours to fully cure.)
