Doing some DIY pool renovation. The old waterline tile was beveled on the bottom edge - so - there was not a recessed bed that the tile was set into. New tile is just under 1/4" thick and is not finished/beveled on the bottom. Any suggestions as to a product to use to bevel from the front of the tile down to the pool wall? I used Henry Feather Finish in the past for some gouges in the plaster/gunite (with epoxy paint over it) and it worked great. But, this is a large area as the pool is 20x40. The brown under the tile in the photos is hydraulic cement which didn't work. We will grind that out and start again. Also, we will be epoxy painting as soon as we figure this out. Thanks for all your help, folks.
