I have lived in a 65+ year-old-house on a slab, no crawl space, for almost 20 years. I used to have two window air conditioners, but I still had trouble with moisture on my walls. I got central air a few years ago which seemed to help greatly. My problem is that I was going to paint my walls, and there was some peeling paint so I started peeling and before I knew it, I had almost all of the paint off the wall. The drywall smells "musty" like a damp basement. The walls are dry but have a chalky substance on them. It also appears these walls were never primed appropriately. Is there something I can do to "clean up" the walls so I can prime and repaint?
Thanks a bunch!
