We're nearing the end of our remodel and we're not happy with the backsplash. We apparently chose a hard tile to work with as there are a lot of little pieces (but sheeted 12x12). Knowing we chose a tough tile, I'm okay that many areas don't have consistent grout lines, I'm even ok with a little lippage. But the showcase area, underneath our hood, looks bad.
The GC has redone part of it a few times but they're saying that the lippage is due to uneven studs. I've done some research and it seems like it might be the thinset was laid on too thick and is shrinking in some places. Is this a normal recent with small sheeted tiles? Can it be fixed?
