Single-Stick 4 oz | Pool & Spa Repair | Easy for Anyone to DIY | Works Underwater or Above | Fix Cracks Leaks in Concrete, Fiberglass & Other Surfaces | by Atlas Minerals

I’ve used pool putty twice in our fill pond, that holds water for our pool filtration system. The fill pond is concrete with a latex undercoat. If it gets a nick from brushing, vacuuming, etc., the latex can be exposed and deteriorate. So, effective patch coverage is essential for any nicks or cracks in the cement top coat. This product works wonders in coverage and holding up to the system’s daily wear and tear. My first underwater application was perfect. Set up, covered nicely and has weathered as expected. Second try was a flop…too little mixing time and too thin patches…they flaked and did not set up. I removed them and started over. This time I used smaller 1” -1 1/2 “ amounts, mixed until quite warm and pliable (2 - 3 minutes), and made even 1/8” thick patches. Voila! Perfect patches that were set up in 20-30 minutes. I’m keeping a spare tube handy, just in case I have more unexpected nicks. This product is a game changer. Prior to this we needed to drain the fill pond and make repairs over the course of several days. Costly and time consuming. Thank you pool putty!

Had small cracks around the spillway in the tile grout. This was easy to apply and seems to be working well

Great stuff! Our pool developed a small crack in the sidewall. Wanted something to fix it for the season and then drain and repair at a later date. Followed the directions and applied it under water. Holding well and should last for the time needed.

I used it on a small 6 inch area in my pool that was both above and under water. It was easy to apply but it never hardened and is now soft and turning yellow/ grey. I will have to pull off and find something better.

It is easy to prep, but the epoxy does NOT stick well. First application lasted. Two weeks then you could see a gap forming between the pool plaster and epoxy. Removed and reapplied again, it just doesn’t stick enough to push the water out and adhere properly to the concrete. May work better in a crack, but doesn’t work on plaster area that had peeled.

It’s a little pricey but it worked for a small job. But it does get messy

I rarely write reviews, only if a product is extremely bad, or a product is extremely good!This product falls into the latter!I have tried many different products to patch leaks on the floor of our inexpensive 12' above ground pool. none of them worked UNTIL I tried this product. it sealed a 1/2" hole made by a rock in seconds! and the tiny ones elsewhere as well. it saved me from draining the pool. it hardens under water so it wont get pulled off easily. I wish there were 10 stars!

Perfect for underwater and easy to use patched a crack in my pool tile grout with ease
