I recently started removing my old aggregate pool deck and I made the mistake of assuming the pool coping was concrete with aggregate on top but the aggregate is the coping. The exposed tile is anywhere from 2-2.75in from the top of the pool deck. Shouldn’t the tile be installed uniformly the same height from the top of the pool deck. So in summary and I apologize if this is a dumb question but how do I install new coping with the overhang flush to to top of tile if the tile is not all the same height? Just an FYI, I eventually want to replace the tile when I refinish my pool but I don’t have the finances to do everything at once.
