Underwater MagicHorizon Sealant, 9.8 oz Tube, Blue UWM-02

I have an in ground liner pool that developed a quarter size hole in the corner of the deep end. To say the least the loss of water was substantial. In comes this product. I put on my scuba gear (you don't need it) and layered the sealant over the hole. I laped it one inch bigger than the hole and used my fingers to make sure it was consistently sealinging. Worked Immediatly and by the next day's it was well cured.One year later, 2024.The original repair job is a solid as the day I repaired it. Why check? I found another hole in my liner today. The liner is four years old, so it is a year or two from its life's end.Using some of this left over from the original repair, put on a mask, jumped in and sealed the leak. Works like a charm.

I used this to repair a cut in the flor of my vinyl inground pool. I cut a patch from leftover liner put this glue on the patch and dove to the bottom with a snorkel. I managed to do the repair in one breath and left a weight over the patch. The glue cured underwater and the patch has held so far all summer. Very happy with this adhesive!

Pega Perfecto las piezas pero se seca muy rápido porque el aplicador no se puede cerrar bien deberían cambiarlo por algo más fácil de usar y que cierre bien para que no se seque

Used product to fasten a murial to pool bottom, it stuck to pool for about 12 hours. waste of $60.00

We had some significant deep end cracks in our old fiberglass 26k gallon pool that was installed in the 70s. At first the product was difficult to smooth out and wouldn't stay in place but we began using a soft cloth such as an old t-shirt and it smoothed beautifully. Our water loss has stopped . Very happy with this product. Application was 9 feet under water and some cracks were over a foot long.

We only wish that it came in white.

This is an amazing product. Did some tile repair in my spa and couldn't be happier. The thing that I like most is that it doesn't harden ROCK hard, it has a very slight give to it so that if knocked it can take the hit. Hope that makes sense. Anyways the adhesive is really really good and the stuff went a long way. I would highly recommend this product.

Can install this caulk under water. Works very good.
