Flex Seal2 oz white spray

Had a pinhole like in my pvc 3/4" water pipe. Followed instructions on the can and applied 2-3 coats. After 24 hours, leak was still there. Saw this advertised on tv and thought it would work. Wrong...waste of time and money

    Flex SealOrdering/customer service

    I ordered directly from Flex Seal's web sight. After a couple of weeks I got an email from them saying sorry for the delay of my order but I wouldn't be billed until the order shipped. Then after another week or so I got a charge on my credit card for the product. So I waited to receive my order. Then just the other day I got another email saying sorry again but my order was delayed. Cancelled order, don't deal with this company! Very bad customer service.

      Flex SealFlex seal liquid in aerosol can nozzle exploded off and product went into face

      Grabbed a brand new can of the aerosol product.
      Shook the can like any other to mix the contents.
      Pushed the nozzle down and the oroduct immediatly leaked out around the nozzle.
      Took pressure off the nozzle and it popped off and product sprayed all over including my face. Thank God I was wearing my safety glasses. Got a rag and wiped off what I could washed with water to neutralize the chemical reaction and called customer service to see what the best way was to get off of skin particularly around my eyes and face.
      Although the associates were nice enough they only suggested liquid Dawn or the higher second level suggested LAVA soap. ON A FACE?! I'm not dainty but my wife would cringe at the idea of using lava on a face and rubbing. REALLY!?
      No suggestion of replacing product or anything worst experience ever. THERE ARE OTHER PRODUCTS on the market and I suggest to use them as at least they are not "habadashers" selling like the old west! Time to talk to legal.

        Dear flex seal, 5/4/2020
        I writing to let you know of a problem I have just discovered with a can of your spray-on flex seal. Three weeks ago, I built a new large storage shelving unite in my garage and collected all my spray cans and loaded the shelves with them. Along with all my cans was a new can of your flex seal. Two days ago, I went to the garage to use the flex seal and found that the spray can of flex seal had apparently exploded and covered the shelves and the floor with a brown sticky liquid. I left the can just where I found it to show you that the plastic top of the can shattered when the can exploded. I have all the pictures you might like to see and thought you might like to comment on what has happened.

            Flex Sealflex seal liquid

            I repaired cracks in concrete stairs with this product and it worked. Then painted it only to find paint doesn't stick to it. Called customer service to find a solution to the problem only to get a confirmation - paint does not adhere to it and my only solution is to remove all of it. No where in the can or product literature does it say NOT PAINTABLE. Now I have a big, fat mess on my hands that could have been avoided with the addition of two words to the label. I was warned not to eat it and I think the likelihood of painting it is far greater than than me eating it. Pretty stupid.

                Flex Sealflex seal rubber coating

                Have a pond that is 12 inches deep and 3' x 4' wide. Wanted to coat it so it would not leak. Bought 3 gallons of Flex Seal from Lowes at a price of almost $ 300.00. Coated it 8 times and let dry for 24 hrs. each time. Pond still drains down. I feel that this was an extremely wast of money? You make your product look so bullet proof on TV but in real time not so good. I'm not only very disappointed in out all that money. Thanks.

I followed directions spraying an even thick coat and letting it dru and repeating this untill i used an entire 14 Oz. Can and it did absoultely NOTHING to seal this tiny pinhole... The leak is the same today as it was when i started. This product does not work at all. I am very disappointed and i will be sure to let everyone know this about your product.

Do you not want me to have it? The last one I sent on June 26. Please tell me what I have to do. I have not been given an order number. I am very upset about this.

                      Bought a can and it worked great but didn't use it all so I sealed the lid back onto it and than later when I went to use it was a solid rubber didn't know if this is what it was suppose to do or not but I wanted to know if I would get some of my money back or not. Can't remember where I purchased it at right now I would have to research my recites.
