Putting up a kitchen backsplash. Wife thinks adhesive mats are the way to go, I would prefer thinset. There’s a section that will go behind the stove so will likely see a good amount of steam. Not sure if that would qualify as a “high moisture location” where adhesive mats are counterindicated
In that case, will steam be able to get behind the tiles if they’re grouted and sealed properly?
(I’d use thinset, personally, because I want to do jobs once and forget about them. If you might redo it in different tiles in 5–10 years, you don’t need to be so concerned with longevity, maybe.)
