I am looking to get new wallpaper for my home. Can wallpaper be on concrete walls given how humid Japan is. I am asking because when it’s so humid the tiles on the stairs sweats. I just don’t want mold growing. Current wallpaper show signs of mold but no one has lived in the house for 4.5 years so the house wasn’t aired out.
Thanks for your input.
