(2-Pack) Calvana Underwater Pool Putty Epoxy

I love this stuff. Hardens like a rock. Allows me to fix pot metal chairs and weathervanes without brazing. Easy to apply and mold to shape. Sets up in an hour, but soft and pliable to work with. Not a race to the finish, like some materials. Epoxy putty, gorilla glue, and some duct tape goes a long way for some red green fixes without too much skill, knowledge, or danger (like using a welder). Recommend.

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.

Great adhesion IN THE WATER. Works wonderfully for patching a step on a swimming pool (using a piece of PVC to add strength.

easy use fast delivery goes along way with 2 tubes, will keep it in a cool place to see how long it lasts will stick to anything. hardens very quick , got to be an artist to make it look smooth lol... wish it came in colors

Good

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

It would not adhere or dry under water, but if used above the water line it works very well. I do feel you need to drain your pool below where the repair is being made. If you do that, it should work well.

This is the third product I've used for underwater repairs. First, unlike all the others, this does not cure white, it remains a pale green. I should have realized that the description didn't indicate the cured color of the product. Second, product did not seal at all, either above the waterline or below. I'm going to have to try to remove it and use one of the other products. I thought the price was too good to be true. I wouldn't recommend this product.
