Underwater Magic Sealant, Mosaic, 2.1 oz Tube, White

Used this to reattach pool tiles that had fallen into pool. Not wanting to reduce the water level I tried this in a full pool. The tiles adhered despite being under water. Just what I needed to fix my pool.

Attempted to use it the same day it was delivered. Product was so dry it could not be forced out of the tube, regardless of pressure. I have never left a review on any product before, but this product (expensive for the small amount) was so completely useless that I felt compelled to.

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

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.

Great for small pool tile repairs--works underwater and seems to hold really well.

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.

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.
