Does not work under water as stated! Does not seal up the best. Needs a better airtight method!
Does not work under water as stated! Stays on putty knife and will not spread under water. Just globs and falls to bottom of pool! Great product for sealing around things. Was not sealed the best and had to waste quite a big ring of paste as they had not air sealed it the best. Also seemed to not be that full of a pail. Used it to patch the walls of my above ground pool around jet and skimmer. Plan on using to patch the liner inside in 2 places as well. Hopefully it does not harden before I can use the rest. I sealed it as shown and hope it does work.

Works great.
This product works great. Unfortunately, the pail I received had a good part off it already dried up and unusable. That was a bit disappointing as I was short material to get the job done.
