Wall design - Cladding panels in the living room?

Alternatively, you attach a wooden slat at the height and grid spacing of several stones that you leave free for this purpose and screw the cabinet onto the slat. If you want to move the cabinet later, you can unscrew the slat and fill the gap exactly with the stones you have set aside for this purpose. In that case, the cabinet hangs absolutely straight as long as the slat is thicker than the stones.

So about the mold. I think cladding is hardly affected by it. Concrete is, as far as I know, not a good breeding ground for mold and then a cladding wall is anything but flat. I think if you put a cabinet in front of it, enough air can circulate anyway due to the conditions.
