removing old ceramic tile adhesive?
I”m doing a small repair on a poorly designed bathroom floor consisting of ceramic tile glued with organic glue, not thinset, about the color of butterscotch. It is glued to 3/4 ply over joists. I want to get the residual glue off the ceramic tile easily, if that’s possible. I’ll rebuild the bathroom in its entirety in a couple of years, and for now am going to put it back the way it was. Can I boil the tiles in lye (NaOH) without hurting them or their glaze? Is there another easy removal technidque? PhilZ
