I'm planning on installing corrugated galvanized metal as a wainscoting in my bathroom. Is there anything I need to put behind the metal to help prevent mold/moisture from getting behind it? The walls are plaster.
This is the picture my girlfriend pulled off of Pinterest. I would run the corrugated metal vertically at 48 in in height. It looked like a good idea because it would match more of my personality and lifestyle, living on a farm. I've read where people have used it in bathroom surrounds with little issues, however I haven't found anyone who has had it installed for more than a few years.
