Quick question: I have just finished scraping wallpaper off
a wall that the previous bozos ... I mean, homeowners ...
hadn't bothered to prime, paint or size. The other walls had
been painted, luckily. I scraped off a gouge before I realized
this wall was different, also I used a paper tiger and was a
little zealous in a few spots and left dings in the drywall paper.
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.
After all this work, I don't want to make more work for myself
by skipping a step. Thanks for any help you can give me.
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
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
room, I am a Gardz believer.
Partially correct- Gardz will seal like a shellac. But it
(and this is the beauty of it) 'penetrates' and will bind unsound
surfaces together like a glue.
After 30 years of hanging wallpaper and running into many types of
wall conditions, I'm a HUGE Gardz believer.
I don't know what we ever did without it.
You're correct, I left that out in my
original answer. You can see the
penetrating action because all the
drywall carboard turns darker in color.
As I said, you have to be careful to not
saturate the area too much,
or the bubbles will likely appear. But
my experience shows that it
doesn't happen too often.
How large is the "large scrape"? Your method will probably be fine, but
sounds like overkill.
Pin holes from the paper tiger need only spackle, at most. Probably
would fill with primer. Since
you said one wall had never had primer, I would buy a latex primer that
can be used on new drywall,
and spot prime the patches too. Then prime the whole wall. A good
paint store will have the right
primer and paint for you. Gouges in drywall are standard stuff. When I
have torn dryeall paper, it
got a little messy because the paper stuck out through spackle. A ball
peen hammer fixed that. Spackle
the dent and go on.
If you mud over the scrapes and dings, the moisture in the mud will
seep into the gypsum core of the drywall and you'll have more
FIRST -- seal the dings and scrapes -- there's a Zinser product, I
think it's called Gardz or something like that. It's basically a
varnish that seals the surface to which it's applied so moisture won't
-- Seal with Zinser Gardz, let it dry according to package directions.
-- Mud over the dings and scrapes -- use a light application of mud,
even if you have to put on 2-3 layers. Light application will dry
quickly and saves you from having to sand down a big lump of mud.
-- When you have a smooth-as-a-baby's-bottom surface, let it dry 48
hours or so until you detect no moisture in the mud.
-- Prime with a good quality primer.
Thank you! to everyone who responded. Being the holiday
weekend, I wasn't able to find the Gardz. I bought something that
I hoped would do the job, an oil based primer. I got a spray can of
Kilz original interior oil-base primer-sealer-stainblocker. I sprayed
the areas where I'd inadvertently scraped off the drywall paper.
Let that dry, then put on a coat of primer. Cleaned up the rough
areas with drywall compound. It turned out great, just a little sanding
and I'm ready for my finish coat of paint. I did that a little out of
but all's well than ends well.
Just wanted to let you know I appreciated the advice.
