Easy Installation Of Your Wallpaper
Wallpaper Installation Guide – with 20 mm overlap
Preparation - Make sure that the bare wall is sound, clean and dry. Remove all loose paint, plaster or old paper and fill all holes and cracks with filler, smoothing down the surface when it is set.
"Size" The Wall - Prior to wallpapering it's a good idea to "size" the wall as this seals porous surfaces to prevent the paste from drying too fast and it also aids slip and slide when papering. Beeline Primer Sealer is a highly recommended wallpaper "size" product as it does all of the above and also helps reduce seam splits, raised edges and bubbling of wallpaper.
Start Line - Few walls are truly square or perfectly vertical. To overcome this, use a plumb line or spirit level and draw a vertical pencil line from ceiling to floor at a set distance from the left hand edge of your wall. This start line measurement will be either 600 or 1200 mm depending on the wallpaper width you have ordered.

Helper - it may be helpful to have two people install your custom printed wallpaper.
Start With Panel 2
Line the left hand edge of Panel 2 to the plumb line you have drawn.
Your custom wallpaper panels are designed to be overlapped by 20mm at each seam.
Continue with Panel 3 on the RHS making sure the pattern repeat or image is matching across the two overlap areas so the design continues seamlessly. Finish finally with Panel 1 on the LHS once all others have been fitted
Pasting The Wallpaper
This paper is a Paste-the-wall non woven paper.
Apply undiluted adhesive to the wall surface to be covered using a medium pile roller and a brush for cutting-in.
Only paste one drop area at a time. Use a soft spatula to apply the wallpaper to the prepared surface using a smooth up-and-down motion.
Take care not to squeeze the adhesive out at the edges.
Simple and Perfectly Matched Seams
Your finished wallpaper will look great just as it is with the overlap. But for a close to seamless look you may decide to double cut your panels to trim the overlap.
Double Cutting - a technique used to obtain perfectly fitted seams. This is done by overlapping one panel of wallpaper over the other until the image or patterns are perfectly matched. Then a sharp blade is used to cut through both layers. The excess edges are then removed.
To trim the overlap you will need a straight edge and a wallpaper trimming knife (Harris Wallpaper Trimming Knife). Make a clean, straight, vertical cut through both of the layers at the centre of the overlaps. You may need to frequently change blades (just snap off old blade).
Then peel away the waste on the top layer and lift the overlap and peel away the waste on the bottom layer. Smooth both layers back down, wipe away any surplus adhesive. The result will be a nearly invisible seam between the panels. The nice thing too is that the razor line itself doesn't need to be perfect. Just keep your eye on the middle of the overlap and keep going, slowly.
Continue to install panels and double cut the seams in the same manner until your entire mural is hung, finishing finally with Panel 1 on the LHS. Take time to make sure everything is smoothed properly into place and that all edges are stuck down.
