Installation guide

Wallnia non-woven wallpaper is easier to hang than classic wallpaper: you paste the wall, not the paper, and the numbered strips arrive ready to hang. With a little care, allow half a day for one wall. Here is the method, step by step.

What you need

  • Non-woven wallpaper paste (available in our shop : 1 tub for about 10 m²)
  • Paint roller or pasting brush and a tray
  • Smoothing spatula (or wallpaper brush) and a clean, damp cloth
  • Cutter with a new blade and a metal ruler (or wide filling knife)
  • Spirit level or plumb line, pencil
  • Stepladder

1. Prepare the wall

The wall must be clean, dry, smooth and even. Remove old wallpaper, fill holes, sand down irregularities and dust off. On new plaster, apply a primer first. On a dark or multi-coloured wall, a white primer stops the background from showing through the paper.

Switch off the power and remove socket and switch covers before you start.

2. Lay out the strips

Unpack the strips and lay them out in numbered order. Check the direction of the design (the top is marked). Do not cut anything in advance: the 5 cm margin is trimmed once the strip is stuck.

3. Draw the first line

With the level or plumb line, draw a perfectly straight vertical line for the edge of strip no. 1. Do not rely on the corner of the wall, which is rarely straight: this line ensures the whole wallpaper hangs perfectly aligned.

4. Paste and hang

  1. Prepare the paste as instructed on the tub.
  2. Paste the wall with the roller, over the width of one strip plus a few centimetres. Do not put paste on the paper.
  3. Hang strip no. 1 along your line, letting it overlap slightly at the top and bottom.
  4. Smooth from the centre outwards with the spatula to push out air bubbles.
  5. Hang the next strips edge to edge, without overlapping, in numbered order. The design joins up perfectly.
  6. Wipe off any paste straight away with the damp cloth.

5. Trim the excess

Press the ruler or filling knife into the corner of the ceiling and skirting board, then cut with the cutter. Change blades often: a new blade avoids tearing the paper. Around windows, doors and sockets, make a cross-shaped cut, then trim flush.

6. Let it dry

Let it dry for at least 24 hours, away from draughts and strong heating, before putting back furniture and socket covers.

Our tips

  • Work in pairs for tall walls: one holds the top of the strip, the other guides it.
  • If a strip is out of place, gently peel it off while the paste is still wet and reposition it.
  • Keep an offcut: handy for a small repair later.
