Can I save grout damaged by low pH?

[Fixit]

Thank you for that answer PoolDoc. I was afraid that would be the case. I used a heavy duty stone sealer - hoping it might treat the grout like sandstone and penetrate deep to protect it for now. Crossing my fingers. I will look into the K2006. Thanks again!

Good luck!

at least it will be easier , to replace if the thinset comes right off.. usually tile is adhered with thinset . grout is only between the tiles not holding them on

My hope is that the thinset will hold true so the tiles stay put and all I have to do is scrape the grout out. The tiles are penny rounds :/
