Underwater Magic Water Resistant Tile and Grout Repair Sealant 2.1 Oz Tube, White

Bought this before when we developed a crack around my pool's skimmer. I was able to apply it underwater, and it is now fixed.

I went to use this product 32 days after reciept. the adhesive was hardened in the tube. the tube was unopened.

Had leak in pool and I fixed the problem. It definitely adheres to wet area with no issues. I thought it was a little pricey for a small tube but it is worth every penny. Easy to use and very high quality

worked really well to glue back tile in my skimmer area without draining the pool. Also glued a decorative turtle to the pool wall. It does seize up in the tip of the tube though, so you need to use it up if possible. It is pricy but it works really well.

Really works

I bought this as it seemed to be the only sealant that can be applied underwater. See photo of where I applied this product around the lower trim edges of the pool skimmer entrance. NOTE 1 - This is a small tube. I had just enough for this small project. NOTE 2 - When I trimmed the plastic tip to apply I could get nothing to come out. It turns out that some of the sealant had hardened in the tube tip. I worked with the sharp point of a large safety pin for 5 minutes to eventually work the blockage out so the caulk could flow. See photo. NOTE 3 - The caulk was very difficult to squeeze out of the tube. The consistency was VERY thick and took the maximum pressure I could apply by hand to squeeze out what I needed. NOTE 4 - The caulk is extremely sticky, even underwater. Be sure to use disposable rubber gloves and have a roll of paper towels handy to rub off any that gets where you do not want it. It cannot be removed from clothes. NOTE 5 - This caulk, like all others, must be "pushed" into the cracks for proper adhesion. Refer again to Note 4. NOTE 6 - Regarding the blockage in the tube nozzle and the thick viscosity which made application difficult. I would be interested in hearing the seller and manufacturer comments on this. In case what I received was an expired product I have included a photo of the tube band stamp. Finally, I think next time I will try to purchase directly from the Manufacturer, Horizon Spa & Pool Parts, Tucson, AZ, in the hope that a "fresh" tube works better than what I received.

I ordered 2 tubes, one was usable the other already hardened and unusable. I had read about this happening in other reviews, but didn’t think it would happen to me. I was wrong.

The stuff is rather viscous so somewhat difficult to squish out of the tube by hand. Clean up anything that is not in the place you want it because it definitely stays put. I had a very small patch to make and it was completely underwater.It's still holding 3 weeks later. My hands are not terribly strong so you might not have any trouble at all.
