I have a hole to patch in a wall but I am not sure what is exactly covering the wall or how to go about patching such a large space.
It's only 1/8" thick and not secured to studs (drywall) or wood (plaster). It has the consistency of drywall, however. The walls behind it are stone. There are no studs. It's not masonite. I'm at a loss.
As of now, the hole is about 9" x 6", but it'll likely be bigger because the covering seems to have buckled from the wall. I tried using a 8" x 8" drywall patch, but it didn't seem to work too well with the size of the hole + the buckling (it doesn't make for a uniformly even surface).
If I know what the covering is, I would buy more and try and patch by cutting out a replacement piece/square.
(I tried posting pix but it is not working for me for some reason)
