It worked for me!
I’ve seen ads for Flexseal products and thought they sounded too good to be true. I recently had to repair the vinyl floor in a car trailer. It’s rarely used yet some of the vinyl flooring was torn and otherwise damaged. I have been looking for a cost effective repair, with no luck. On a whim I ordered some of this Flexseal putty. It worked perfectly for this application. I basically wanted to cover the damage to make it less noticeable. It far surpassed my expectations. I now intend to go back and make the repairs more carefully and expect the results to be close to the original.

Pond
My wife used FlexSeal Paste to glue hundreds of rocks to the inside wall of the plastic pond liner. Works great so far! One rock at a time!

Worked for me.
I found it easy to use and it stopped the inflow of water for me. I just think it is a little more expensive than it should be. The container was just too small for the price.

Unspreadable Block
This is supposed to be a spreadable paste. When opened it was a solid block which couldn't possibly be spread. This was in temperatures between 55 degrees and 70 degrees. Product is either ancient or defective. And price is ridiculous for a tub about the size of a large yogurt container. Don't waste your money.

Love the product but this particular one was old
I was going to use this product to fill in some really bad cracks in a blacktop driveway. Product works. Have used before. But when this container came about 1/3 of it was dried & hard. Do not recommend ordering from here.

50% of the contents of tub was dried out and therefore unusable.
The product itself is good, but the value for the money is very poor, as it arrived with half of the product dried out and unusable.
