2-Part Set | Swimming Pool & Spa Repair | Easy DIY | Fix Cracks Leaks Underwater or Above | Concrete, Fiberglass & Variety of Other Surfaces | by Atlas Minerals

This product worked great on my soft side pool window. The frame of the window had a very odd crack/gouge that wouldn't allow for a sheet/glue type patch. Product went on easy and stopped the leak immidetly. Set up hard and is doing exactly as advertised.I'll update if anything changes 🤞🏻

This is great stuff we used under water to seal paint when it started peeling under water from the concrete poolAfter applying last summer we scrubbing cracked paint this spring and we scrubbed the paint but the sealer sticks on concrete like a rock and doesn’t come out and we cannot scrub it from the concrete pool no matter how we triedWe was cutting equal size of the pool putty resin and pool putty hardener 1-2 inches pieces at the time and kneaded two pieces together for a few minutes as instruction said i don’t remember until it soft and we pushed it on the pool walls where was paint peeling under water and after it sticks little bit we spreading it as fast as we could covering cracked areas as more as possible until it’s hardened and doesn’t spread anymore under water and we never cleaned surfaces before or after applying itWe did this In lots of areas many times and it’s hard until this year spring and we cannot get it out from pool before repaintingThe only hope that paint will stick to that sealerBut if not then it is white and our pool paint is white and will be not much differenceFor those who gave 1 star I know exactly it is working even under waterBut it possible that they didn’t not knead it properly or enough time as said in instructions or used whole thing at once which would be hard to knead it or just used one of the two parts of hardening part separately and resin part separately ?That’s the only things I can think aboutBecause we were using it a lot on our pool under water last summer and cannot get it from the pool next spring right now because of extreme hardness of this two parts pool putty productIf it worked for us under water on top of peeling paint and without any knowledge but just kneading two equal parts for 5 minutes or so I don’t rememberI put time on alarm clock on my phone how much to knead it. It is so hard now in 9 months after pain pool started peelingWe used it also on the skimmers cracks andIt didn’t come out alsoIt’s lots stronger than the cement patches sealers in my experienceThe only it’s not much in the tubes and I had to order lots of it to cover large areas under waterBut it is pretty affordable as long as don’t raise the price :))

This stuff works as advertised. Perfect. I wish they had different colors instead of white but that worked out for the best as afterwards I went to get pain color matched and painted over the putty and looks fantastic. Great product.

yes it works, but you must mix dry -- do not it wet while mixing. Its hard to adhere, requires lots of force underwater, but it does cure underwater.

This is an outstanding putty sealer for pool and works great underwater. I was able to quickly mix it and get it too warm by the touch of my and and then plug the holes between my skimmer and pool wall. After a few weeks now, it's solid as Rock and no signs of deterioration.

This stuff is great and really works. It’s have a Laguna Fiberglass pool that is 25 yrs old and is losing water at the electrical connection behind the pool light. This immediately seals up the small leak and saves a costly fiberglass repair and avoids draining the 29k gallon pool.

It arrived before I expected. Thanks.

The concept is really simple, the instructions clear, and the process trivial. Cut two slides of equal length, one from each tube, work them together until thoroughly mixed into a uniform paste (it does not stick to fingers, at least not enough to cause any problems), apply where needed, let it cure. I used it in two places on my gunite pool wall to repair seals between the plaster and the tubing, one above the surface (refill) and one below (the vacuum cleaner outlet). Easy to apply in air, tricky under water, because it mixes well with water, so that any manipulation that increases the surface in contact with water also works to dissolve the mix. I found it best to push the mix into place and not worry about the finish until after it had time to cure. As for curing: cured quickly in air, but very slowly (noticeably more slowly than the instructions would have you believe) under water -- perhaps it's because my pool is salt water?The result is more like plaster than like expoxy -- it holds, but it's not especially strong.I still recommend it forits ease of use, and also because I have not found anything better (short of emptying the pool to the level of the repair to carry out the repair in air).
