My house was built by the Army in 1957 and has many quirks. One of the main quirks is that I have 1/4" thick fiberboard(masonite?) interior walls connected by a channel system. My question is two-fold.
1) I have removed a heater fan from a bath wall and intend on patching the 10" x 11" hole left behind. I had originally planned to patch using traditional drywall patching methods. But after finding out the actual thickness of the wall I wonder is there a more preferred and secure method to patch this?
2) How do I get ANYTHING to stay nailed or screwed into these walls? looking behind the face of the wall I see several different attempts at using plastic anchors, screwing straight into the wall, nailing, etc. Short of attaching straight into the stud, everything seems to fall out. Is there a product I can use in between studs to keep things like towel racks and picture frames firmly planted in those walls?
If you've dealt with these walls before, do you have any general suggestions about working with or around them?
