Seems to be silicone rubber

Reviewed in the United States on September 14, 2017

Size Name: 16-ozVerified Purchase

Tested a little of this on a roof seam on my camper. It had a slick feel after drying --- uh-oh. I did some research and sure enough, it seems to be some form of silicone rubber. SILICONE is a harsh mistress: you can't paint over it and if you ever have to re-do the caulking, it will leave a silicone film which nothing will completely remove, which can never be painted over, and which no other type of sealant (such as polyurethane) will bond to. Once you have applied a silicone product to a substrate, in my opinion, you have committed yourself to using silicone there forever.

OMG this stuff is amazing. I have a 100 year old house. I have a concrete double-sink for my washig machine run off. This sink had so many cracks and holes. I had many estimates and was advised to replace sink. Could not affort demolition. I purchased one can of this liquid flex seal and 4 cans of the flex seal spray. I had a friend roll on the liquid flex seal inside, outand and underneath. 2 days later he came back and sprayed 1 1/2 cans all over the original liquid seal. After 24 hours, he did it again. I waited for about a week and washed 5 loads of clothes. Voila it worked great. You must understand, my sinks were leaking so bad that I had to use the wet vac to get the water up. No more problems. It is not leaking at all, nowhere. I gave the 4th can away to a friend who started out a non believer as I was. Remember my house is 100 years old and the concrete sink was madeinto the wall.

Difficult to work with

This product will bubble and cause flex to fall off in areas (no idea why only certain parts). They put the stupid crimps on the top of the paint cans which make them almost impossible to take off as well as you will not be able to reseal the paint can afterwards. It's extremely thick so does not cover very far on rough surfaces and it rips the fuzziness off of your rollers or the hairs out of your brushes. It feels like you are working with sticky goo. And it comes off very easily so I would not recommend it for ponds where you are going to be adding rocks.

Edit: Flex Seal has reached out to me to try and resolve this issue, i greatly appriciate a company that stands behind there product. I will update soon.

After repairing the bubbling and applying the second coat i noticed it applies much further when doing a second coat than your first coat on a rough surface. Moving rocks into the pond caused a fair amount of damage to the sealant surface as it seems to be fairly that of a silicone like substance. After testing with water and time, i feel the concrete may have absorbed the product a bit helping these flaws. I have some patching to do but am concerned that since i was not able to close the container due to the packaging crimps i may have lost my other half gallon.

***When it dries, if water is placed on top of flex seal, you will get an EXTREMELY slippery surface.
(Like a cartoon banana peel).*** Be extremely careful if walking on when wet. But on the other hand it could probably make the worlds best waterslide lol

WILL NOT BUY ANYTHING LIKE THIS EVER AGAIN WITHOUT FIRST TRYING IT OUT

UNFORTUNATELY, THIS PRODUCT DOES NOT STAND UP TO THE ADVERTISING IT PRODUCES. MY HUSBAND PUT THIS ON A ROOF AND WHEN IT RAINED 2 DAYS LATER, THERE WAS WATER EVERYWHERE. RUINED SOME FURNITURE AND PICTURES ON THE WALL. WHAT A MESS! WILL NOT BUY ANYTHING LIKE THIS EVER AGAIN WITHOUT FIRST TRYING IT OUT. OF COURSE WE HAD TO GO OUT AND BUY ROOFING SEALANT AND REDO THE WHOLE JOB. SORRY WE EVER PURCHASED THIS. VERY EXPENSIVE AND GOT NOTHING FOR OUR MONEY. SO SAD.....

I ordered this with my husband telling the me whole time it was not going to work. Of course we have all seen the commercial on TV but I thought lets give this a try and let me tell you it works and works great. This is the clear liquid so I cant comment on the tape but do try this if you any leaks. We had one where we had had a leak where we had once had a vent in our roof, fixed by a roofer. Several years later we had a regular rain storm and it was leaking in our attic. Hurricane Irma was on its way and that is what my husband used even though we ended up with a 24 hour tropical storm it held. Give it a try.

Perfect product to save the day!

Reviewed in the United States on January 27, 2018

Size Name: 1-galVerified Purchase

I like having the option to paint this product on! It gives you way more control over where it is applied, compared to the spray! I have used this for several different applications.
I have painted window sills, that my gutters are back dripping onto, it repels the water & keep the wood from rotting. I have sealed gutter seams that were leaking. I painted the inside of a metal trash can that I am using as a Faraday cage to protect my electronics. I figured a layer of rubber would definitely help break the conductivity & keep things safer inside.
It does have a VERY strong odor, it took me several days to air out the can I am using for my electronics. Once it is completely dry, it does start to fade, but not completely.
Having this around to use & being able to apply as much, or little as I want, is why I got this in a gallon size. You just never know when you are going to need it & when you suddenly do need it, it is nice to have more than a cans worth, which can run out pretty fast when there is actually a situation that needs tending to in a hurry! The fact that it is clear is also a bonus, it works with what ever color your using it on.
