Well I painted a previous crack that I had put epoxy AND cement plug and NOW I painted the entire repaired crack in my basement wall with the Flex seal.... So I tripled my chances of stopping this leak... do I hope the Flex seal does it job.... YES.... and I am hoping their advertisements I see on TV will work...... in other words I do NOT know if this product works NOW, but soon maybe.. good luck....PS i have NOT instant feed back to give... good luck to you..

I used this along with the flex shot on my inground Pool skimmer. It has been leaking for about a year and repairing it properly would cost about $800. I spoke with my local pool store and asked him what he thought. He said that it should work. I applied flex shot first. I let it dry 24 hours. I then went and bought cheap paint brushes. I applied one coat of flex seal threw away the cheap brush and let it dry and cure 24 hours. I repeated this 2 more times. After the third day I filled the pool. 2 weeks and the leak is cured. Water level has not moved. This product is absolutely amazing. I have some left and will annually apply a coat for maintenance. Total cost to repair was less than $30.

I have a ComfortAir bed. It's about 20 years old and I get very small air leaks in the bladder at the seam. I sealed the leaks and I'm using Flex Seam on the seam to strength it. It will take some time sleeping on it to see if it works. I think Flex Seal is a good product. Anker

Awesome product. I have used a few products to stop water from entering the corner of my basement and none has worked but this Flex Seal liquid has.

Used this on the front casting deck of my fiberglass skiff and really happy with the results. This stuff is really thick so don’t think it’s going to go on like paint, you’re applying a rubber coating, and you can’t stir it. I used a brush and small 4” foam roller. Pretty sure it will waterproof any surface it adhere’s to. Don’t know how durable it is yet but I’m pleased so far.
