I have a 100 year old house and have started removing wallpaper. The
original layer appears to be the old-fashioned all paper wallpaper
applied to an unpainted plaster wall. Some of it is adhered so tightly
that many small areas of damage to the plaster ocurred on removal. I
plan to fill the holes and damaged areas with joint compound and
reinforcing tape, and then use wallpaper liner to smooth over the
imperfections. I have several questions:
1) do I really have to prime the walls first?
2) can I use sizing instead?
3) can I size and put the liner over the old paper?
This notion is flatly wrong. If there is settling there will be
cracks. I don't care what compound is used.
However, it may cause bubbling (which usually drys out flat.)
If you do this, you will (probably) be ok BUT if you have unsound
surfaces underneath you are simply compunding the problem.
I'd recommend stripping the old paper off, patching, & priming with
ONLY Draw-tite or Gardz. It will make removal easier next time around.
And it will penetrate & bond any unsound surfaces underneath.
Uh, I do this for a living. 26 years.
