Looked at doing a drywall patch job at a friends apt. complex. The drywall seems to be made out of maybe cement. Could it just be old drywall. Never seen it before. Its not plaster. Its sheets and taped. Any sugestions? Thanks

Where is this building located, and how old is it? Are the sheets 4x8?
About 15 years ago there was a Sheetrock substitute around here. It was a dense gypsum product with no paper facing. I forget the trade name. I think it didn't sell well because it was very heavy.

Yes, they are 4x8 sheets. I would guess it has been at least 30 years since it was remodeled. Could be some very old fire rated stuff. Many cracks. Dosen't seem to be very thick tho. I'll rip into a wall on Mon.
You say it appears to be made of cement and that it's not very thick?? Sounds like ΒΌ" CBB. Where in the building is this stuff installed?

Way back when, in the early days of drywall, it was common to do a sort of drywall with skim coat, and I believe that the "drywall" product used was kind of rough faced, not really intended to be finished without a skim coat, but folks may have just taped and painted it anyway.
It's also possible that you're seeing drywall where the paper face has been peeled away, possibly during wallpaper removal.
Finally, there was a drywall product produced about 25 years ago that was unfaced gypsum reenforced with wood fibers. It theoretically could be finished without tape, with some sort of fibered mud.

Drywall has been around since the late 20's/early 30's
He's refering to a product that is about 30 years old (or so)
Probably not the same stuff :)
I have had to remove some stuff called "Tuff Rock" that was a lot like the stuff you describe. It was installed in the late 60's/early 70's around here. It looks and installs just like drywall, but the core product was more like concrete. Very difficult to cut with a rock knife. I wound up just removing whole sheets and reinstalling standard drywall for the repairs.

James, I believe you are right. I'm just going to rip it all off. Thanks, Steve
