Underwater Pool Putty Epoxy - 2 Part Set, Quick Set for Spa, Hot Tub, & Pool Leak Repair - Bonds to Fiberglass, Concrete & More - 8 oz Total, Easy DIY Waterproof Sealant – Work Like Magic

I have used it in two application-one on hot tub repair for one of the jets where there was a leak at one of the PVC fittings and another on the heat exchange manifold on my diesel engine on the boat. Not sure if this is a permanent or temp size, but solved the immediate problem.

This stuff did work to patch a small underwater tear in our above pool liner(Intex). It worked well for awhile, but it did eventually start to work off though and come loose slightly where water would slowly leak out again. We do have lots of kids that come over and get pretty crazy in the pool though, so I think maybe if I patched it from both sides of the liner it may have held. I only applied it on the inside underwater and that’s why maybe little feet kept hitting it and loosing it. I would give it another shot and spend more time next time patching on both sides and I think that might have done the trick. Summer is almost over though so this will be a task for next year when there’s no water in it.

Our pool cleaner has a hard plastic ring that got stuck in a particular area near our pool step. It would sit there and hump that area until I moved it. Before I corrected the cleaner, it had knocked off a piece of the pool surface totally off. The rest is in gray shape and it’s not time to redo, so I bought this aqua colored epoxy (after kneading) and slapped it into place. It matches fairly well and I can wait to resurface the pool again. Highly recommend!

Pool leakEasy peazy

Purchase this anticipating it would be waterproof as are the other sticks I have purchased from Pinch-A-Penny into the past. This is definitely not waterproof and immediately leaked. Maybe for other applications it would be fine but not for what I needed

Best product of its kind

Product doesn’t work. Says it can be sanded or drilled in 30 minutes. 24 hours later it’s still soft. Also used it in pool says it’ll work under water and cure, not at all. Don’t buy this stuff.

Used on our in ground pool stairs. They have slight cracks in corners. Cheaper than replacing for now. I think spreading it thinner works best. Put on a bit thick in an area and came off. Thinner areas held and is doing the job!
