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 stuff is fantastic, and if you have an in-ground pool, do yourself a favor and keep some of this on hand. It works on any kind of pool except vinyl liners, but even those have steps that this can be used on.Clean the surface of any loose debris or algae, and if it’s really smooth, rough it up with a wire brush or some sandpaper. Use rubber gloves to mix up equal parts of this until it’s a uniform color, and push it on. Done.I hope this helps.

worked great under waterreplaced 4 tiles with product. easy to use, just need to hold the tiles in place for several minutes and let go, thats it

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.

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.

Super easy to use. Just cut equal parts for what you need, mix then apply.I liked to use small amounts, getting into those cracks with a fair amount of pressure. Even applied under waterAfter a few months, this product is still

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!

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.

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 🤞🏻
