Wallpaper Installation and Repair Q&A
Be sure to scroll down... there may be more than one question on this page!
I'm preparing walls for wallpapering and need to patch a couple of
small holes. I've found that my big old tub of spackling paste is very
thick. Do I need to go out and buy a new tub or can I add water to
what I have? I've tried it in a couple of small holes and it spreads
fine, it's just not real goopy. Thanks in advance.

Partially dried spackle is... partially dried. This is the
equivalent of adding sand to fresh spackle. It loses some of it's
strength and smoothing ability, and if the holes are more than tiny...
screw holes, picture hanger holes... it may not even hold in the wall.
I am not a big fan of old-time spackle. It doesn't work "off
the knife" very well and it dries very hard. This was fine when
all the walls were plaster, but today's softer walls of paper-faced drywall do
better with a softer, more easily sandable filler. So instead of plain old spackle, get a
container of the newer lightweight spackle. It is a relatively dry
product that is very workable, and dries so quickly you can paint over
it within a half hour under normal circumstances. In fact, you can
paint over it immediately with latex paints if you find a very small
hole, such as a nail or picture hanger hole, as you are painting!
I want to use interior flat latex paint over wallpaper that's well adhered.
Is it worth the effort to strip the paper rather than just paint over it?

You can definitely paint over wallpaper, but I have mixed feelings about it.
First, the seams will show through the paint unless you carefully coat them with
a skim coat of wallboard compound to hide them. Second, you must use an oil
based primer to seal the paper, or the latex paint could cause the wallpaper
paste to soften, causing the paper to "bubble". Another
"hidden" problem is that many wallpapers have a texture... sometimes
not very noticeable until painted. Flowers, anyone?
Even if the paper is vinyl (which generally does not let water through) it is
wise to prime because using a good oil-based primer-sealer will insure that the
paint will stick to smooth vinyl surface.
The reason I don't suggest painting over wallpaper is that if the wallpaper
begins to fail, the walls will begin to look very ragged. The repair is not
difficult… simply cut out all the loose areas and smooth them with wallboard
compound. Since wallpaper failure tends to be progressive, this process of
failure/repair will continue on and on over the years. If you spend the time now
to strip the paper, you save yourself future disappointment.
Once you paint, the removal process becomes much more tedious and difficult,
since the paint has removed any porosity in the paper and also stiffens it by
adding more thickness to the wall. The more coats of paint, the worse it gets!
Nowadays, with the high quality chemical wallpaper strippers available,
removing wallpaper is not as much of a chore as you might think. Messy, yes, but
not catastrophic. I have an article at the site that discusses some of the
issues in wallpaper stripping.
We have wallpaper on our walls that was painted over by the former
residents. I would like to know if there is an easy way to remove it.
It is always difficult, and sometimes impossible, to remove painted-over
wallpaper without damaging the walls... especially if your walls are wallboard
or a similar product. Plaster walls can take more moisture abuse and can
stand more abuse. That is why the number one choice is to just leave it on
the walls. With the proper repairs, all but the most awful wall surfaces can be
restored to their original smooth glory!
The general procedure is to cut out all loose areas of paper and level the
walls with wallboard compound, as if you were fixing shallow holes. You can
similarly cut back loose seams and fill them. Once you do all the repairs, a
coat of an oil-based primer is required to seal the walls. If you use a
water-based primer, you may cause more of the wallpaper to release where you
don't want it to! Also, though water-based primers have really improved over the
last 20 years, they still tend to dissolve stains and carry them to the surface
of the paint, leading to possible bleed through into your finish coat.
Removal of the paper is another more serious and more difficult task. Paste
dissolving chemicals and/or a steam wallpaper remover will be your tools of
choice in this endeavor. Of course, for the chemicals or steam to get to the
adhesive beneath the paint/paper collage, you must somehow mechanically pierce
the paint film. One old-time method is to use a stiff wire brush to abrade the
surface of the paint and paper. Fast forward to the 20th Century… there is a
retail product called the Paper Tiger that does this a little more neatly and
easily. The Paper Tiger is a small hand-held tool that has hundreds of small
pins attached to wheels. Rolling it over the surface of the wall introduces
hundreds of small holes, usually deep enough to penetrate the surface but no so
deep that you will require extensive wall repair afterwards. This product is
commonly available at paint stores. The only drawback is that it may not fully
penetrate through multiple layers of paint.
One you have sufficiently scored the paint film or paper, you can begin
stripping the paper. You have two options. You can use a chemical wallpaper
stripper, available at any paint or hardware store, which is mixed with hot
water and sprayed on the surface of the wall. The chemical dissolves the paste
and helps lift the paper from the wall. Your second, more severe option is to
use a steam wallpaper stripper. Many paint stores and rental centers have these
available, and will provide instruction in their use.
If the above methods fail you, the final and least desirable method would be
to use a chemical paint stripper. Because these products are very toxic and
possibly damaging to many other surfaces (including your body), I list this as a
last resort when other less dangerous remedies have been ruled out!
How can wallpaper be removed when it has been directly applied to the
wallboard. The builder did not put ANYTHING on the walls prior to the paper,
including paint! A small corner I tried to remove would not budge.
I have seen wallpaper applied over raw, unpainted wallboard many times in
both private homes and condominiums. The most commonly used technical term for
this timesaving contractor technique is CHEAP. Other widely used terms are LAZY,
INCOMPETENT, and UNPROFESSIONAL. The builder may have saved a few dollars, but
the homeowner pays dearly for this breach of trust... trust that the contractor
had done the job right.
You must use either a wallpaper steamer or chemical stripper to remove the
paper. Either method may damage the wallboard surface, especially if you have to
make intense use of a scraper to remove the paper. Once you get the paper off,
your job has only just begun. Now you have to repair all the damage done to the
surface of the wallboard to give you a smooth surface for either wallpapering or
painting. Even if you were to "texture" the walls, some preliminary smoothing
will be necessary unless you were going to use a very heavy stucco-like texture.
Have you considered the possibility of not removing the wallpaper at all? If
the wallpaper is well stuck and doesn't have a textured surface that might
appear through the paint (big embossed jungle flowers are my favorite), you can
prime the paper with an oil-based primer. This will seal the wallpaper so that
the moisture from water-based paints or patching compounds will not loosen it or
cause it to "bubble". Any loose areas or imperfections should be cut out prior
to priming. This is especially true of the seams... even the slightest looseness
will cause later attempts to hide the seams (read on) to fail. So trim back the
seams to where there the paper is absolutely solid.
Seams can be a problem because they will show through the paint unless given
special treatment. Prime all the wallpaper first. Then apply a few thin coats of
wallboard compound to the seams just as if they were taped wallboard joints,
tapering the coating out at least 10" on either side of the seam. This will
thoroughly mask the seams making them virtually invisible.
Once all the miscellaneous repairs and seam repairs are sanded smooth, prime
the repairs alone or (if it's easier) prime the entire surface again. Then you
are ready to paint the walls with the paint of your choice. Proper sealing will
ensure that your job will last!
We are trying to remove vinyl wall covering from our kitchen walls. In some
spots, it came off with ease, but there are other spots where we cannot get a
scraper between the vinyl and the plaster. We tried using a wallpaper remover,
but it has no effect on the laminated surface of the vinyl. We also used a heat
gun to soften the adhesive, but it's not making it much easier. What can we do,
short of ripping the whole wall down, to remove the vinyl?
Some vinyl wallpapers can be very difficult to remove. The reason is that the
surface of the vinyl is nonporous. This is fabulous in kitchens and bathrooms...
vinyl's resistance to water and chemicals allows it to be cleaned and, with some
heavy vinyl's, scrubbed!
Alas, this quality is a two-edged sword, especially when wallpaper removal
time arrives. The same nonporous quality you valued earlier becomes a curse!
Many vinyl papers are called "strippable", meaning you can lift a corner and the
vinyl will easily pull apart from a lighter paper backing. The backing is porous
and application of wallpaper stripper makes cleanup a snap. There are
unfortunately some papers, like yours, that will not pull off without a little
In a nutshell, you need to perforate the surface of the vinyl to allow the
stripping chemical to get through it. This can be accomplished in two ways. You
can purchase a special tool designed for this job, called the Paper Tiger ( I
had to look the name up... I had a mental "skip" and became fixated on the name
"Wallpaper Weasel" but, after some reflection realized that was probably some
wallpaperer's nickname!) This device, available at virtually all paint stores,
perforates the paper in random patterns as you roll it over the wall surface.
The second, less high-tech but effective method is to use a stiff wire brush
and scratch through the surface of the vinyl. Be careful not do dig too deep or
you may have more wall repairs to do later!
With either method, you may have to soak the face of the vinyl a number of
times for the stripper to work. Be patient and you'll eventually be rewarded!
