Great Results When Used on Roofs
The feedback left for The Flex Seal Liquid Rubber in a Can was overwhelmingly positive. People who need for fixing their roof had a lot of good things to say.
Here is one of those comments: “I had a flat roof redone with heavy asphalt/gravel sheeting. A year later I wasn’t happy with the joints where the sheets met, and the gray paint that had been applied was cracking along one area. I had no evidence of leaking, but the joint heat seals just didn’t look like they wouldn’t eventually peel up. (Won’t use that contractor again!) So I used Flex Seal on all the joints and over the cracked areas, and it worked beautifully. The Flex Seal really does create a rubberized surface, and it is holding nicely. Btw, the liquid in the can is much heavier than the spray can is. I used a bristle brush to apply.”
Works Great on Pools
If you have a pool that springs a leak, you may want to try The Flex Seal Liquid Rubber in a Can to fix it. People who had pools found the product genuine successfully when trying to fix their pool leaks.
A customer recounted their experience by saying: “The pool of a water fountain had cracked and corroded from winter freezing. It would retain water for about three days and the leak was difficult to locate. The floor of the pool was vacuumed and all debris removed after which the flex seal was poured in. The self leveling liquid filled all imperfections while an old stiff bristled paint brush was used to apply flex seal to the vertical walls. After 24 hours the pool was filled with water and there were no leaks. Four months later, the flex seal has remained secure and the fountain pool leak free.”
Good for Sidewalks
As the Flex Seal remains flexible, it has advantages over hard curing sealants.
A customer who used it on his driveway explained: “If the price is no concern, I like it for driveway cracks and any other exterior weather protection that needs to bridge gaps, flex (duh), and self-seal cuts/punctures. For me, latex concrete repair caulk always shrunk/hardened/cracked. I used a roofing nail to punch a hole right above the bottom rim of the can, I put an air hole in the lid, and I could fill tiny cracks in concrete. First I put a little crushed rock in larger gaps. I put the nail back in the hole to stop it. I used half a gallon for more than 30 feet of crack. I suggest a piece of stiff wire or small brush to smooth/spread it, adhere it to the surface, eliminating pockets. Also with a brush, I sealed a critical piece of wood structure where I would have attempted to use house wrap or tarpaper in the past.”
Great for Outdoor Flooring
Some people commented that they had great results when using The Flex Seal Liquid Rubber in a Can for outdoor flooring.
A customer explained: “We have so far used (including black and clear liquids) it on blacktop, concrete, and painted wood, each time with astounding results. We are currently covering our concrete patio with 3 coats of liquid grey to be then sprinkled with grey, white, brown, and black latex chips (to simulate the appearance of granite) to be then covered with three coats of clear FlexSeal. The idea is to mimic a process used to cover a garage floor using epoxy resin, latex chips and polyurethane. Thus far the grey applications are resolving according to plan. Each coat was even cleaned with a power washer to remove accumulated debris in between coats. Power washing has had no impact upon the FS coatings.”
Good for Metal Bottomed Hot Tubs – Makes the Surface Non-Slippery
One of our friend has personally used this product on the flooring of a dog therapy pool that he made. Because the pool was made from an 8-foot diameter metal stock tank, it was slippery to walk on.

Also, he made this pool in the coldest part of winter in subzero temperatures in his unheated garage, but with the help of a heat lamp directed at the pool bottom, it cured just fine. The Flex Seal Liquid Rubber in a Can made the bottom of the pool not slippery at all for when his dog needed to use the heated therapy pool.
