Got me a hole in my roof! OK so it’s been there for over a year – it’s a small hole and I crawled back into the attic and put a big bucket under it, which is working for now. But hiring a roofer is expensive and frankly, I’d rather have a pool or new carpet. So when I saw this on TV I was pretty excited. I’ve actually got this one on order, but after reading some information online I decided to go ahead and post it.
I don’t intend to try this on my roof first. Although it’s basically a rubber sealant in a spray can, which seems pretty innocuous, I have a better use – the spot on the ground outside my bathroom wall where ants keep coming into the house. Since Flex Seal spray can be painted (it only comes in black), I should be able to apply some house paint right over it. If not, I’ll just plant a holly bush or something to cover it up.
I might even try some funky waterproofing tests like the one on the infomercial, where they cut a hole in the bottom of a boat, replace it with a screen door, and seal the screen with Flex Seal. (Wonder how many spray cans that took?) Here’s the video in case you haven’t seen it:

Flex Seal Questions and Answers
What kind of coverage do you get from a can of Flex Seal?
A single can of Flex Seal will cover 2-8 square feet, depending on the number of coats you use and how thickly you apply it.
Can Flex Seal spray withstand heat?
Flex Seal withstands normal heat conditions including most home roofs. It’s not designed for extreme temperatures outside of normal conditions, though. The same goes for extreme cold temps.
How long does it take Flex Seal spray to dry?
A minimum of 2 hours, and as long as 24 hours. The drying time depends on the temperature and humidity when applied, and how thick of a coat is sprayed.
More Flex Seal Info
Flex Seal has about a bajillion uses. It’s advertised for things like stopping roof and gutter leaks. It can be uses to stop leaks on corroded metal or PVC pipes. You can use it to seal around drafty windows. Personally, I’m wondering if it will work on bike tires, at least as well as a patch does. (I wouldn’t risk it on my car tires though!) If you don’t want to spray Flex Seal onto the surface, you can instead spray it directly into a container (like a cup or bowl) and paint it onto the surface to be sealed with an old paintbrush. The only two places it’s NOT recommended for use are inside any container used to store drinking water, or on/inside any container used to store or transport gasoline.
