The preperation. The preparation. First, make sure the walls are smooth. Remove all wallpaper, adhesive residue and other blemishes. For a good result the surface should be completely smooth! Make sure that the floor is free and equipped with a waterproof sailing. During application of the photo wall murals you might make a bit of a mess.
Draw a vertical line with a perpendicular / level.
For this wallpaper you should use wallpaper glue for non-woven wallpaper, a sharp knife, a squeegee and a level.
Start with covering the wall(!) NOT the wallpaper with the adhesive for non-woven wallpaper.
Hang the first panel against the perpendicular. Make sure you use the right panel (number)! Lay the stroke down gently and (without too much pressure) smooth it out from the center to the sides.
Then stick the next panel on the wall in the same way as the previous lane.
Cut away all the extra material along the ceiling, the plinth and possibly the door jamb with the help of a wallpaper ruler or spatula and a sharp, new hobby knife.
Remove excess glue residues from the wallpaper.
