Currently removing super old wallpaper in my grandma's basement with an end goal to paint. If you see in the top picture, certain sections are scraped to a white, paper-like surface and others reveal a brown, cardboard-like surface.
The second picture is a section of the material I found in the basement that I think was used. Is it some sort of gypsum? It has a Georgia-Pacific label, but no other identifiers. One side is brown cardboard and the other is a white paper-like surface.
It's almost as if some of the sheets were installed with cardboard layer facing out and others with the white paper surface facing out (see top picture). Would it be better to:
1) Rip it down, put in standard drywall, and then paint
2) Scrape it down to the cardboard level, skim it with joint compound, sand/smooth, then paint?
