Before you begin

These are general installation instructions. Always follow any material-specific directions included with your order. If a product arrives damaged, incorrect or defective, stop and contact us before installation.

Tools to prepare

For both materials

  • Tape measure and pencil
  • Spirit level or plumb line
  • The squeegee supplied with your order
  • Sharp craft knife with spare blades
  • Metal straightedge
  • Clean cloth or sponge
  • Step ladder

For Non-Woven wallpaper

  • Suitable wallpaper paste
  • Paste roller or brush
  • Paste tray or bucket
  • Seam roller if appropriate

Prepare the wall

1

Remove obstacles

Take down pictures and carefully remove socket and switch covers after isolating the electricity where required. Remove loose wallpaper and protruding fixings.

2

Clean and repair

Fill holes and cracks, sand smooth and remove dust, grease or residue. The surface must be clean, dry, stable and even. Do not apply wallpaper to textured, glossy, untreated or unpainted surfaces.

3

Allow new paint to cure

Do not install on fresh or uncured paint. Printseekers recommends allowing newly painted walls to cure for 2–7 days; follow the paint manufacturer if it requires longer.

4

Plan the panels

Lay every panel flat, check that none are missing or damaged and verify the complete mural before installing. Follow the numbered sequence and supplied layout, then mark a true vertical guide using a level or plumb line.

Peel & Stick

Installing self-adhesive wallpaper

1

Position the first panel

Peel back only a small section of the backing at the top. Align the panel with the vertical guide, leaving the planned trimming allowance at the ceiling.

2

Apply gradually

Remove the backing roughly one-third at a time while smoothing from the centre towards the edges. Do not pull or stretch the material.

3

Align the next panel

Match the design carefully and place panels edge to edge without overlap. The adhesive allows careful repositioning during initial installation, so check alignment from top to bottom before pressing firmly.

4

Smooth and trim

Remove remaining air pockets with gentle outward strokes. Use a sharp blade and straightedge to trim at the ceiling, floor and openings.

Traditional Non-Woven

Installing paste-the-wall wallpaper

1

Apply the paste to the wall

Use a wallpaper adhesive suitable for non-woven paper. Apply it evenly to the wall or paper as directed by the adhesive and the instructions included with your order. Avoid dry patches and excessive build-up.

2

Hang the first panel

Align it with the vertical guide and allow a small excess at the ceiling and floor. Smooth gently from the centre outwards.

3

Continue edge to edge

Prepare the next section, align the artwork and bring each seam together edge to edge. Printseekers panels are designed without overlap.

4

Clean and finish

Remove excess paste immediately with a clean damp sponge—do not rub. Trim with a fresh blade and check every seam before the paste dries.

Safety, aftercare and important checks

Install safely

  • Keep the room well ventilated.
  • Keep adhesive, blades and tools away from children.
  • Use a stable, secure ladder.
  • Isolate electricity before working around sockets or exposed wiring.

Care after installation

  • Gently clean with a soft, slightly damp cloth.
  • Avoid rubbing the printed surface.
  • Do not use abrasive cleaners or excessive water.
  • Peel & Stick can be repositioned during installation, but is not intended for repeated reuse after long-term application.

Inspect before installing

Do not begin if panels are missing, damaged, misprinted or in the wrong sequence. Photograph the entire mural and the affected area, keep the packaging and contact PosterPeak. Starting with an incorrect panel or continuing after discovering a defect can prevent a reliable assessment.

Common installation questions

Where should I start?

Use the layout supplied with your mural. The first panel must follow a perfectly vertical guide; do not rely on a corner being straight.

Should panels overlap?

Follow the instructions supplied with the material. In most cases panels are aligned edge to edge, but never assume—check before installing.

How do I avoid visible seams?

Prepare a smooth wall, keep the first panel vertical, align the pattern without stretching and avoid forcing the edges together.

What if I notice a defect while installing?

Stop immediately, keep all panels and packaging, photograph the issue and contact us. Continuing may make the problem harder to assess.

Not sure which material to choose?

Compare Peel & Stick and Traditional Non-Woven wallpaper before ordering.
