How To Hang Your Wallpaper

Wild Hearts Wonder wallpaper panels are 90cm in width and are supplied untrimmed. An extra bleed of 15mm has been added to the right of each panel for overlap. Whilst it is possible to hang yourself, we recommend that it’s hung carefully by trained professionals.


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.

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.


Make sure you start in the top left hand corner and work along the wall from left to right.

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.


Line the left hand edge of Panel 2 to cover 15mm of Panel 1 and continue in this fashion.

Your custom wallpaper panels are designed to be overlapped by 15mm at each seam. For the purposes of measuring, 90cm should be used per panel. 

Your finished wall 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 is 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 (We recommend a 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 all the panels are hung. Take time to make sure everything is smoothed properly into place and that all edges are stuck down.



The wall panel is sold in pieces of 90cm width by 2.5m in length. For walls shorter than 2.5m, the wallpaper will need to be trimmed with a sharp decorating knife during the hanging process.

Smooth down the join with a good quality hanging brush making sure the edges are butted against each other and carefully wipe any excess paste from the face of the paper immediately with a clean damp sponge.
