(MOBILE, Ala.) Flex Seal promises to plug leaks without any prep work, and without hiring a handyman. It claims to be the ultimate sealant, liquid rubber in a can. You spray it on and in 24 hours, it's set to work it's magic. Is it a deal or a dud? We found out!
A leaking roof can cost you big money and that gushing gutter isn't chump change either. In it's commercial, Flex Seal claims to be the answer to these problems or the easy way, to coat, seal, and stop leaks fast. Just a shot of Flex Seal instantly fills cracks and holes. If you have leaks around your home, the makers of Flex Seal say this product in a can, can save you thousands of dollars in home repairs.
We decided to do our own test, by drilling about eight small holes in a gutter. Then, we sprayed on a good thick coating of Flex Seal on it. After waiting more than 24 hours, we enlisted the help of construction expert Rafael Maldonado. "It's a tar substance or a rubbery substance, I don't know what it is," says Maldonado.
Anxious to find out what it is and if it worked, we met him at his job. Since it wasn't raining hard enough, a water hose would have to do the trick to see if Flex Seal was up to snuff. "Do you see it leaking through the drill holes, no," says Maldonado. "That gutter, you put just individual little holes in it and filled the holes and it worked alright," says Maldonado.
To give this product another try, we coated our strainer with several layers of the aerosol sealant and gave it 24 hours to cure. "It's coated very thick," says Maldonado.
Into the kitchen we went, Rafael filled up our blackened strainer, and then watched to see what would happen next.
"It's leaking. I am surprised this thing coated like it is, this thick coating on both sides that I filled this with water and it leaked," says Maldonado. "You see that guy on TV, he's in a boat and the bottom is a screen, you imagine doing a whole screen and they're not being one leak, I don't believe it."
A deal or dud? "A dud," says Maldonado.
The product can get messy, it goes on like spray paint. It didn't do a bad job filling small holes. But our construction expert says a handyman in a can, it is not!
