I am redoing the gameroom as a bedroom for my son now that the pool table's
been sold. I'm removing the awful wallpaper to paint, and have discovered it
is wallpaper over smooth plaster over textured plaster over drywall, but
hey, at least it's only 1 layer of wp. Pulling off the paper has pulled off
some of the smooth plaster, and we're going to have to steam off the rest of
the paper - don't know if that'll affect the plaster or not.

We've discovered some drywall cracks, plus my kid put his forearm through
one wall playing ninja warrior and indented the drywall with what looks like
bouncing a golf ball off of it (you know, the stuff that "Idunno" does?), so
I've got some repairs/replacements to make. This whole house had foundation
work done years ago and last summer a SE said it was holding, so these are
older cracks hidden by the wallpaper.

Q1 - there are some cracks over the doorways: must that drywall be cut out
and replaced or is there anything effective that will work on approx 8" long
1/8 - 1/16" crack between the doorframe and crown molding? I used some
flexible rubbery like spray coating several years ago to finish cracks along
a window on a P&B house I sold, but I never saw if it held or not...

Q2 - there are two corners where there is about 1/8" separation between the
two walls the entire height of the wall. How would I best deal with that?

Q2 - Can I just retexture over the smooth plaster spread over the textured
drywall or is there some reason a 3rd layer could be a problem? I intend to
paint whenever we're done with this mess.

TIA - Laurie
