About this item
Product details
Flex Seal is actually 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. Flex Seal coats, seals, protects and will stop leaks fast! Available in 12 vibrant colors. It’s like a…Handyman in a can!
Directions:
Read entire can. Wear face and eye protection, protective gloves, and clothing. Make sure the surface is clean, dry, and free of grease, oil, and dirt. Shake well. Spray 8” to 12” from surface, using an even, sweeping motion. Apply multiple, even coats until all cracks and holes have been filled.
Flex Tips:
Spray a larger area than area where the leak is and feather the edges. For best results, apply multiple coats rather than one thick coat and use at can temperatures above 60ºF. Make sure Flex Seal has filled all cracks and holes and is fully cured before testing product. If light can pass through, apply additional coats.

Flex Seal
The stuff works as advertised, and then some! I have used 4 or more cans on three different projects and I am very happy with the results. Now I wonder about the longevity?

Sealed hole where water leaked into cellar.
Used it to seal a hole in the wall where well water leaked in to the cellar in the spring. Easy to apply. Will know next spring it it's effective.. Bought three more cans.

Works like it says
We used to repair metal building that was rusting at bottom. Used this to seal where new piece of metal was scabbed on. Looks like it'll do the job!
