How to install pre pasted wallpaper

Tools required for the job

i. Worktable
ii. Wallpaper scraper
iii. Clean sharp knife
iv. Large wallpaper tray, or a clean paint roller and bucket
v. Clean water, or for an optional ‘belt-and braces’ approach use a weak adhesive paste
vi. Clean sponge
vii. Clean cloth
viii. Sandpaper
ix. White matt emulsion (optional)
x. PVC (optional)

1. Preparation

Remove any furniture and potential obstacles that may be in your way before you begin. Ideally you will
want to give yourself as much working space as the room will allow. Remove the existing old wallpaper
as well as any old lining paper carefully, taking care not to damage the wall surface.
The result of your preparation is end up with a smooth, straight and clean wall surface, free from dirt,
grease and dust particles. All holes and imperfections must be filled and sanded to restore the wall to an
even surface with no indentations or unevenness which may affect the adhesion of your wallpaper – plus
the finished impact of your graphics won’t look at their best if spoiled by a poor uneven surface for the
design to hang onto!

Let's begin

a. Clear the area of unnecessary obstacles: wherever possible remove wall fixtures for easier
application and a better overall finish to your wall graphics.

b. Protect any areas which can’t be removed from your work area, such as carpets and large heavy
furniture, with covers and dust sheets.

c. Using a clean wallpaper scraper carefully peel away the old wallpaper taking care not to damage the
wall surface beneath. For hard to remove wallpapers you may find it easier to lightly soak the
wallpaper with a sponge and clean water first to loosen the wallpaper adhesive, alternatively use a
wallpaper steamer as directed by the steamers user instructions

d. Once all the old wallpaper and liner has been completely removed, level out any uneven wall areas
ready for application of the new wallpaper. Fill holes, scrapes and imperfections with suitable filler;
remember to build suitable drying time into the time allocated to the job!
Once dry, sand the affected areas down to a smooth, even finish (both on the wall and to any
damaged surrounds such as skirting or sockets which may also need some fresh paint when finishing

e. Ensure the entire wall surface is sound and straight and wipe with clean moist cloth to remove
remaining loose dust and particles from the surface. We recommend painting the entire wall area
with a matt emulsion to even out any color tonal differences on the wall surface which may show
through the wallpaper and then applying a coat of PVA to seal the surface. This will provide a better
surface for re-positioning/lining up the wallpaper design during wet application.

f. An additional tip to help adhesion it is recommended to apply a thin coat of weak adhesive paste to
the wall surface and allow to dry on the wall before applying your wetted wallpaper. The wall
surface is now ready to receive the wallpaper.

Useful preparation tips

● Artwork / Design: Careful measurement of the wall area prior to designing your wallpaper is
essential for the design to fit perfectly. As most walls are not perfect size, horizontally or vertically,
ask your designer to allow at least 20mm extra to the longest measurement when creating the
artwork to allow for this. By allowing this extra ‘play’ in the printed artwork your design will be able
to fit onto the wall without the risk of leaving unsightly gaps at the top, bottom, left or right of the
wall as the wall size will differ from one end of a wall to the other.
NB: It is extremely difficult to make complex designs/shapes line up perfectly across walls, so avoid
designs that flow across adjoining walls.

● Printing: This product is designed to work on a whole range of Eco and Eco Solvent printers. To
make the wallpapering process as smooth and trouble free as possible, the media must be given
enough time to dry before use, particularly with solvent inks. With very heavy ink coverage, the
printed media should be allowed to stand very loosely wound for at least 24 hours to allow out
gassing. Always check the print before trimming or pasting. If the heavy ink areas feel soft, or mark
easily. It needs more time to cure.

● Trimming: Always ensure all trimming is done extremely accurately, i.e.: perfectly straight, clean
cuts for the left and right paper edge joins. Accuracy becomes especially important when
symmetrical or repeating patterns are used as inaccurate trimming will result in mismatched patterns
and/or unsightly gaps or overlaps in your joins.

2. Application

Always ensure all trimming is done extremely accurately, i.e.: perfectly straight cuts for the left and
right paper edge joins. Accuracy is crucial when symmetrical or repeating patterns are used as inaccurate
trimming will result in mismatched patterns and/or unsightly gaps or overlaps in your joins.
It is advisable to cut your wallpaper graphics exactly to size and butt the trimmed edges together on the
wall. Alternatively allow extra artwork ‘bleed’ between strips then overlap the wallpaper edges and
splice/trim on the wall.

Splicing on the wall probably offers the tightest fitting joints but for inexperienced installers poor
splicing on the wall will result in damaging the wall surface/plaster and may damage the joined edges of
your design resulting in ‘hacked’ looking joins and subsequent paper lifting.

Let's begin

a. Draw feint plumb line guides on the wall to the size of the strips to ensure your application will fit
and be vertically straight across the entire wall.

b. Cut the wallpaper strips accurately – left and right edges to be trimmed perfectly straight so that the
edges butt perfectly against each other when on the wall.

c. Prior to applying wetted wallpaper, work from left to right offering up each strip without wetting the
paste side. Start at the ceiling and align with the vertical plumb line. Figure out height and width
variations across the entire wall surface in the design stage and prior to actual application, double
checking the extra artwork you allowed at the top and bottom of your design is aligned and will
cover the entire wall area without leaving gaps top or bottom, left or right.

Once you are happy the wall design can be positioned and aligned across the entire wall, soak the
required pre-pasted strip of wallpaper with the water using the following methods:

Fill a bucket half way full with water then spread the wallpaper out design side down (paste side
up) on the work table. Generously apply clean water (or optionally use a weak adhesive paste)
over the entire pre-pasted side using a paint roller leaving no dry areas.

d. With the wallpaper laid out on the work table gently bend a section of the paper back and attach it to
the middle then back again and again so that the entire piece of paper is folded accordion style
without any creases and lightly held to one another.

e. Dampen your sponge. Pull back one section and place it at the top of the wall leaving enough of the
extra design as judged necessary from stage 2c. Press the first strip of wallpaper onto the wall. Use
the sponge to press and stroke the paper onto the wall. Make sure there are no creases, cracks,
bubbles or tears.

f. Pull back the next section from the folds. Press it down and with the sponge smooth the paper.
Continue on with the rest of the wallpaper strip.

g. With a sharp knife and a hard straight edge neatly trim excess paper off the top and bottom edges.
Trim around sockets, switches and other fixings by carefully trimming out the required shapes
leaving enough extra wallpaper to tuck neatly behind the fixings. Wait for the strip to dry and then
re-attach fixings firmly back onto the wall.

Take your next strip of wallpaper and repeat steps 2d through 2h accurately aligning the patterns so
that it looks continuous to the eye from a short distance. Continue in this manner until the walls are
completely covered.

Useful application tips

● It is crucial to a good result that all trimming is done extremely accurately or your joins will look
unsightly. i.e.: if the cuts for the joins aren’t absolutely straight the design won’t match up between
joins, and unsightly gaps or overlaps will become apparent after application to the wall.

● Always use a very sharp, clean knife so your trimmed edges are as cleanly edged and perfectly
straight as possible.

● Smooth the wallpaper slowly and make sure to use a sponge not your hands to avoid handling marks
