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 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.

The media could not be loaded. Works fine to repair leaks where skimmer box meets tiles in gunnite pools. The grout between tiles and the skimmer box in gunnite pools is a common place for older (mine is 1985) in-ground pools to leak. Why pay $300 - $500 (or more) for pool "leak detection and repair" companies to come out? They are only going to use this product if the leak is between tiles and the PVC skimmer box! Easy to detect and repair yourself! Search "skimmer box pool leak and repair" on YouTube to see how to detect and fix these kinds of leaks. You also need a syringe of "pool leak detection dye" to see and confirm the leak. I find I have to redo the repair every 3 years. Easy and much more economical than a $32,000 pool resurfacing makeover!

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 :))

We have a cement pool & knew we had a leak somewhere. We had an idea where the leak was and we used this product under the water to fix the leak and it worked great. It doesn’t take long at all for it to work! We haven’t had any issues all summer so we will see how it look next summer.

Outstanding product, simple to mix. I used it underwater to replace a tile that had come loose. Did not have to drain the pool. I have also been able to seal joints that have opened up. If you take your time and plan the repair it will come out perfect. Dries in a day.

Excellent product. Simple to use underwater. Sealed our pool with ease.

This stuff is fantastic! I help to maintain the community pool for our condominium association, which is an oval pool with fiberglass sides and a plaster bottom. The caulk between each of the fiberglass panels had deteriorated and we were losing significant amounts of water through the seams. We considered draining the pool to re-caulk the seams prior to opening, but with the heavy storms and flooding in our area, we were afraid that hydrostatic pressure could do further damage to the pool. After quite a bit of research I found this product and it seemed like the perfect answer.I cut the compound, including the cardboard tube, in sections about 1 inch long from each tube and mixed/kneaded the two materials per the instructions. I then rolled the product into strings about the thickness of a cigarette and applied them to the seams, both underwater and above water. When I ran out of material, I mixed more, doing it in this fashion to ensure that the product didn't begin to harden before application.Application was simple, and it was easy to smooth the material into place and ensure a tight seal with just my finger. I sealed all 10 seams with one set of the product. I checked the seams after an hour, and every seam still looked perfect and the product was literally as hard as a rock. Time will tell if the product holds up as promised, but I see no reason why it should not. Using this product was actually far easier and less expensive than using Vulkem Seal or a traditional caulking product, and was easier and neater to apply. I also expect it won't deteriorate like other sealants. Based upon my experience so far, I would definitely recommend this to anyone requiring a sealant for similar purposes. I also intend to make this product known to my local pool supply company to recommend to others with similar issues.
