is the difference between pre-pasted and un-pasted wall
All wallpaper murals fall into one of two categories;
Un-pasted. Most of the manufacturers of
the un-pasted murals place a small packet of powdered paste inside the box at
the manufacturing facility. The powdered paste must be mixed with water and
brushed onto the back of the mural before installing. The un-pasted murals
arrive to you in panels. Each panel is approximately 4' x 3'. You apply the
panels to the wall one at a time to create the mural. All un-pasted murals are
printed on a heavy paper stock, they are not washable. This is true with ANY
un-pasted wall mural sold anywhere. The pre-pasted murals are actually
pre-pasted wallpaper. They arrive to you in 18" wide rolls. The height of the
particular mural you purchase will determine the length of that roll, but the
width is always 18". The paste is already on the back of the mural. To install
you simply unroll a panel and dip it into water, let it sit for a few minutes,
and then smooth onto the wall. Each panel is numbered so when you put them up in
the right order they will create the picture. The pre-pasted murals are washable
with soap and water and removable by simply peeling away from the wall.
Un-pasted murals usually require some scraping, but neither pre-pasted or
un-pasted murals will harm the surface of the wall.
I put a mural on my wall if it is concrete, cinder
block, has a rough stucco or orange-peel texture, or
already has paneling on it?
Yes - depending
on the type of wall, you may have to do one the
paper: Using a heavy duty adhesive apply
Heavy Duty Wall Liner to the wall where the mural is to be placed.
Sometimes it helps to paste both the wall surface and
the back of the lining paper since the lining paper is
porous and heavy. Once the lining paper has dried, apply
a primer/sealer. If applying Heavy Duty Wall Liner to
cinder-block, concrete or wood paneling, it is best to
use an un-pasted wall liner and liberally apply a heavy
duty adhesive. This will ensure that the wall liner
stays on the wall. Other methods include:
Floating the Walls: Use a broad knife to trowel
the joint compound over the rough walls in light, even
coats. After the wall is at the preferred smoothness,
allow to dry. Prime the newly smooth surface with 2
coats of primer/sealer. Or using a heavy duty adhesive,
apply a Heavy Duty Wall Liner to the wall where the
mural is to be placed.
Sanding: If the texture is minimal, this process
is adequate and time-saving. After sanding, a
primer/sealer is applied. This method is the least
preferred, however, because of the labor and the dust
that covers the entire house. Applying a
Heavy Duty Wall Liner will also cover lightly textured walls.
Wood-paneled walls: Wash thoroughly with a
de-glossing solution and water, then sand smooth. Fill
vertical grooves of paneling with spackle and apply
primer. Seal with acrylic or alkyd primer, allow to
cure, and hang wall mural. Or using a heavy duty
adhesive, apply Heavy Duty Wall Liner to the wall where
the mural is to be placed.
Q: I live in Florida and we
have "orange peel" textured walls. Can I install a mural on "orange peel"
textured walls without smoothing them first.
A: Yes. You will want to use
an un-pasted mural and use a little extra paste when applying. There are two
very good reasons for this.
First - a pre-pasted mural does not allow for an overlapping in the seams. As a
result the seams may not line-up correctly as one side of the seam may be high
and the other side low. This will create an unsightly gap. An un-pasted mural on
the other hand, allows you to overlap the seams slightly to eliminate this
Secondly - The pre-pasted murals need allot of surface contact with the wall in
order to stay in place. If the paper is resting on the high areas of the texture
it will surely not stay in place for long. An un-pasted mural will allow you to
add a little more paste than you normally would if applying to a perfectly
smooth wall. This extra paste will help 'fill in' the lower areas of the texture
and help create a better bond for the mural.
I found a mural that I like but it is too big for my wall. Can your murals be
trimmed down to fit my wall exactly?
Trimming a mural to fit your wall exactly is quite common and necessary in some
cases. There are a few murals where trimming more than a few inches will ruin
the scene though. Examples; "Soft Breeze" and "El Paradiso". Trim away enough of
the mural so that you can easily work with it and then when it is on the wall
and completely dried, do a final trimming with a razor knife.
your murals be used outdoors?
A: No. Wallpaper murals are for indoors
only. There is no product that you can spray on, brush on or use to cover a
wallpaper mural that will allow it to be displayed outdoors. There are websites
selling wallpaper murals that will be happy to tell you otherwise, but only
because they want to sell you a mural.
Q: Can I apply a wallpaper mural on
new unpainted drywall?
On new drywall, apply a pigmented
wallpaper primer/sealer, followed by 2 coats of FLAT
In order for the paste to
'grab' the wall, the paint must be completely dried. The longer that you wait -
the better, but at least 48 hours. Be 100% sure that you used FLAT interior
paint. Satin, semi-gloss, eggshell etc will not allow the paste to adhere
properly and as the paper dries, it will begin to separate from the wall.
