Hey guys, I had 2 pool tiles that fell off today (see attached pics). I would like to get them back on. Can anybody tell me the proper way to set the tiles back in place on the wall? I'm guessing some type of mastic/thinset to glue the tile back on followed by some sort of mortar a day or two later? Should I use anything special to try and clean the tile off first? Any specific brands of materials (thinset and mortar) that work best in this situation that y'all can recommend? TIA
