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.

Outstanding Product
I used the Flex Seal product on a sky light that had been leaking. I am not an accomplished handy man, quite the contrary but the product is very easy to use and the results were Outstanding. I used the product on Saturday morning and although the directions recommend allowing 24 hours to completely dry, the rain came about 12 hours after sealing the skylight. Didn't see any leaks from the gentle shower Saturday evening. Sunday morning was a hard driving rain for several hours. NO LEAKS. I couldn't have been more pleased. The only caution I would advise is to make sure you order enough product. I wound up using 1 1/2 cans on my large skylight. Glad I ordered 2 cans.

Easy to use and works exactly as promised
We masked off area in our shower to use Flex Seal instead of the rubber grout in a tube and it is so much easier. No more blobs of grout to smooth out because it sprays on and seals just as advertised....great for the purpose we used it for. We are next going to try the inside and outside of our gutters. I am sure it will work perfectly.

Good Product
Did a great job stopping the water coming the sill plate of my sliding glass door. I put the first coat on, waited about 12 hours to fully dry applied the second coat and have not had any water enter the house since. I think that the price was reasonable, but shipping and handing was a bit much! So if you can drive to a store that sells it that is what I suggest.
