I'm wondering how much you value your time.

FWIW, I would never ever spend that much time trying to save a $5 sheet of
rock. In a day, you could remove all the wallboard in a room completely and be
starting fresh putting up new rock. Another option might be to apply a thin
3/8" wallboard right on top of what is already there. This would give a new
smooth surface and added sound insulation. Double layers are commonly used in
studios and places where sounds need to be deadened. In either case you would
need to know how to mud and tape, unless you hired it done.

Dear Experts,

You may have read my other post recently:
Tough dual layer wallpaper removal

Anyway, it turns out that there was in fact an
original layer of paint. Then a wallpaper liner
that was painted. (And then another layer of
wallpaper which I have since removed.)

I don't know what "wallpaper liner" is - reference to the first layer of
wallpaper? From my experience, the number of coats of paint or layers
of wallpaper are pretty irrelevant. Wallpaper, in the best application
possible, is still something I would not want to paint over because it
will eventually loosen somewhere and leave a mess. Getting through the
layers to the bottom layer of wallpaper paste is the sectret. Cut
through with coarse sandpaper, spray a couple of times with water and
let water soak in, then start peeling/scraping. Has always worked well
for me - messy, but low on the "technical difficulty" scale.


I had a thought. A few walls have the painted
wallpaper attached REALLY well. I was thinking to:
- remove any loose paint, etc.
- plaster the wall with a trowel
- sand smooth
- repeat if necessary
- prime with oil based primer
- then paint

Has anyone tried this? Or dealt with the
aftermath? What is your experience? Ideas?

Thanks
