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

it is expensive for 2 oz. but it worked and did what it was supposed to do. It is a small tube and I was able to replace 4 mosaic tiles with it. I had to buy another tube to replace 1 more.all negative reviews talk about an old or expired product, NOT the product itself. expired milk does not mean the milk itself it bad.it worked underwater and cleaned up nicely.you just have to get used to it and learn how to use.also, once opened, you have to use the whole thing, you can not use some of it and hope to use the rest at a later time.overall I'm happy with it

I opened it up and it was hard as a rock. You can’t use it. I had to throw it in the garbage. I didn’t even think about if you guys gonna take it back because you can’t resell it.

It worked to repair broken waterline tile.

Works really good, I wish it came in different colors though. The white really stands out. It is very sticky so have a few pairs of gloves on hand when you use this. Use the entire tube once you open it. It does hold up under water. I used it to go around my return outlets.

Product high quality, great adhesion

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 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
