Im new to this forum. I have been a member or another pool forum and have browsed this one for some time now. I kept seeing more activity in this one so I decided to join.
I have a tile that came off the spa wall right at the waterline during a small freeze (its an gunite inground pool w/spa). I saw many other tiles so I removed them and followed the crack. It ended in the spa spillover that overflows into the pool.
I plan on sealing or bonding the crack, then using bathroom waterproof thinset to place the tiles and then sealing with grout.
What could I use to seal/bond the crack?
What kind of grout will waterproof seal the crack between two tiles?
