I've read, here and elsewhere, where professional or at least
experienced tilers say to use grout in the expansion joints. Or maybe
it's not termed an expansion joint, according to them? Anyway, the
joint where the tile meets the wall, tub, etc.
What's the reasoning on using grout instead of caulk? Aesthetics, I
imagine. But is there not a concern among the pro-grouters about
buckling, or cracking? Or do you simply accept that as a risk and deal
with it when it happens?
I'm no expert, but I had mine buckle last year; oh, what a joy. And
now others are loose. More joy. Personally, I don't think sanded caulk
looks that bad to outweigh the advantage of, at least possibly,
alleviating the buckling. Do I understand the two sides correctly?
