Can I save the grout or at least postpone major repair?
Our water comes out of the tap "hard" but after opening the pool this season we were fighting with the pool water that read as soft and with a VERY low PH.
We have tile that I put in myself just 2 seasons ago up at the waterline. I also repaired some copping stones, Cut out, cleaned out and repaired the expansion joint, and repaired sections of the bond beam. The rest of the pool is plaster. But the waterline tiles are starting to come of and the grout that is covered by the water is turning to sand.
Is there a sealer I can use to prolong the life of this grout? I read that soft water can pull the calcium and bonding agents from grout and cement and I am thinking that that's what has happened to us. Please HELP!
