Can I just use drywall patch over those small areas, then paint?
Googling, I saw that someone had a problem doing that, that
they should have shellac-ed over the damaged areas first.

I've used spackle on dings in drywall numerous times and never had a
problem with it. Just
be sure you allow plenty of drying time, especially if using alkyd paint.

Now that I've called around and can't find the Gardz, I've decided
to give the one larger scrape a coat of BIN before spackling. Then
the whole room will get a coat of BIN.
Thanks for the post. I'll remember about the drying, appreciate the
heads up.

Just been there, done that, as they say.
The wallpaper, vinyl cloth, came
off pretty easy, however, there were
some spots where the drywall surface
was damaged. The problem arises when
you put wet mud in these spots.
The moisture soaks into the paper and
causes bubbling just beyond the
damage spot. If you scape and remud
these spots, you might get bubbles
a little further out .... and so on and
so on!. My wife searched on the net
and found, as someone suggested, Zinzer
Gardz. We rolled it on in a very
thin coat. There was only one spot
where additional bubbling occurred.
We probably put too much Gardz on that
spot. Once Gardz dries, it is
no longer water soluble. So, mudding
over this doesn't seem to cause
additional bubbles. After the mudding
and sanding, I put a coat of Gardz
on the mud areas. Later I primed with
Zinzer tinted water based primer
and then painted. It looks pretty good.

BTW, Gardz, from what I can guess, is
acrylic varnish .... looks like the MinWax
acrylic varnish product ... even smells
like it. I would think that shellac would
probably work similarly. After the
frustrations of brute force patching in
another
room, I am a Gardz believer.
