Underwater Magic Sealant, Mosaic, 2.1 oz Tube, White

Product does what it is intended to accomplish. works well with small patch jobs in the pool grout.

Ordered this product in March and haven’t even opened it yet. Went to use it and it’s solid. The product is still sealed. It can’t be returned and it says I can’t get in touch with the seller. That’s a wasted $20!!

Sealed a small 6ft long crack in a saltwater gunite pool. March 2022. Last 2 years and is still holding strong.

Did not try to use until 2 months after receiving. Stored in original packaging inside my temperature controlled house until ready to use. Could not be used, it was dried up, hard as a rock. Wasted my money on this obviouly old stock item.

Worked really well. I applied it to some mosaic tiles that came loose on the divide between my spa and pool. It has been over 3 weeks and no issues. As others have said the sealant is difficult to get out of the tube but the application was easy, cleaned up easy and has held up

Tiles came off the next day

I have a crack in my in-ground concrete swimming pool. I used this product to seal the underwater crack 6 months ago, and here is my honest review: it is OK. It did help somewhat. Now that time has passed it has not held up (chunks of it is gone), so overall not happy.

Had a couple pool tiles fall off and this stuff worked without issue. Placed a little on the back of the tiles and the tiles held nicely. No issues. Very happy with results.
