I recently purchased a home with an in-ground pool constructed in the mid-70's. It's a gunite/plaster floor with fiberglass side panels. The plaster needs to be redone and I'm leaving that to the pros. The tile is age-worn and needs to be replaced. The quote I received was fairly insane so I figured why not try to do it myself. The tile is actually set into a 3" plastic channel that seems to be mounted at the upper edge of the pool wall (there's a 3" rubber/plastic coping at the top of the wall that caps off the tile channel so I'm not 100% sure how it's held in place). I did the demo this weekend which went smoothly (half the tiles were ready to pop off on their own). Before I go to the next step of buying and installing new tile is anyone familiar with this type of mounting system? Anything I should watch out for?
