There are bathroom tiles on the wall (natural stone), the bathroom tends to get pretty humid (pre-code/no ventilation, do our best to keep it low). We are seeing that a few of the bathroom tiles are beginning to flake off--there seems to be a veneer and a dusty material underneath. What's the recommended way to fix this in the short-term? (there's the systemic solution to get rid of the humidity, but during the interim we don't want to inhale this underlying tile dust). Thank you!

I've never see natural stone do that. Are you sure that's what it is?– JACKJan 12, 2020 at 22:13

It must not be, there is a dust-like substance flaking from underneath--should have said it's purely a stone-like veneer (seems to be made out of a vinyl/plastic material).– SlapChopTBoneJan 14, 2020 at 4:54

It appears that your wall is failing. Whatever those tile are, they weren't intended for bathroom use. You can scrap off the loose particles and then apply a thin layer of caulk or sealer to the area to prevent you from inhaling the dust. How many tiles you're taking about. Other than that, you're going to have to plan on redoing the walls. The tiles will probably continue to fail even if you improve the ventilation.
