1) Preparation is key
To begin you need to get your walls wallpaper-ready; this involves making them smooth, clean and dry. Start off by removing any old wallcoverings, using a wallpaper steam stripper (such as the Energer stripper, £22.99 from Screwfix Direct). By scoring vinyl papers (and make sure you do it gently!) you allow the steam to do its work and can then peel it away with a stripping knife. Having done this rinse the walls, before lastly patching up any holes left with filler (if required) and leave it to dry.
2) Get rolls from the same batch
Ensure that each roll of wallpaper is from the same batch number to make sure they are exactly the same shade (it will state this on the label).
3) Better too much than too little..
When you measure the height of your wall be sure to do it from the top of the skirting board to the ceiling. Make sure you add 5cm to allow a 2.5cm overlap at both ends; this can be trimmed off after the pasting to allow for a crisp finish.
4) Don't forget the seam lines!
Be sure to consider seam lines by using a plumb tool or spirit level to draw vertical guidelines.
5) When it comes to wallpapering...
Cut the strip of wallpaper to size, before laying it onto a pasting table. Having done this apply the wallpaper adhesive. Let it soak in before, using the guidelines, smoothing the paper onto the wall with the pasting brush, allowing the 2.5cm overhang at both ends.
6) Have scissors to hand
To finish lightly score at the ceiling and skirting joints, before peeling the trim back and trimming it with scissors. Wipe away access paste with a damp sponge and voila!
