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

Ok I was too lazy to drain the pool and I had some cracks in the plaster going on well below the surface in my inground gunite pool. I honestly didn’t think this stuff would work but wow, I was wrong. I had no issues getting it to stick to the cracks and it sealed so fast. You just knead it up and roll it into long skinny “worms” and then just place it on top of the cracks underwater and push down. 10/10 product!

I've used this to make various repairs to my gunite pool. Some above the water line and some under. It's never failed me.

Have used it 3 times, first time 3 years ago. Excellent hold after 3 years. Very durable.Dries at an appropriate speed to let you finish the job.Stops pool leaks when applied to correct areas.

It did the job

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 :))

Good pool putty that worked well and is priced right. It dried strong and hard and fixed my leak.

Easy to use

Purchased twice. First batch worked as advertised. Mixed, applied, and hardened well. Second batch had result similar to others. Mixed, felt it getting warm, but when applied under water, would begin to dissolve and would be extremely soft to touch. After 24 hours, still pliable and would dissolve when rubbed.
