How to Prepare Your Walls before Wallpapering

When wallpapering. Preparation is key. Before you even consider wallpapering, take a step back and look at the surface you plan to cover. Are they currently wallpapered or painted? Do they have cracks or bumps on them? Are they freshly plastered?

Our short guide below will help you identify how best to prepare your before wallpapering depending on their current condition. 

Before you begin

  1. Clear the room - if possible, move all the furniture, furnishings, etc. out of the room.
  2. Cover up - cover existing flooring with dust sheets to protect them.

Previously wallpapered walls: 

  1. Strip down - strip off any old wallpaper and ensure the walls are smooth and dry.
  2. Dry off - if using a steam stripper leave your walls to dry off for a few hours.
  3. Create a clean slate - fill in any cracks and holes. Make sure walls and filler are completely dry before wallpapering
  4. Smooth out - when dry, sand the filler so you are left with a smooth, bump-free surface. Make sure any other debris such as dust, paper scraps from your old wallpaper or excessive adhesives are cleaned off your walls to prevent bumps underneath the surface of the paper. 

Previously painted walls: 

  1. Clean off - wallpaper paste needs to partially soak into your walls in order properly adhere. If there is grease or another impermeable substance on your wcalls this will need to be properly cleaned off before you begin. 
  2. Sand Down - sand down any existing paint work to create a rough surface for the adhesive to stick to. 
  3. Follow steps three and four above to create a clean, smooth surface. 

Freshly Plastered Walls:

Walls that are freshly plastered will need to be primed so that the new wallpaper will bond to the walls.

  • For the best results prime your walls by brushing them with watered down wallpaper paste all over the walls and leave them to dry.

Top Tip:
We recommend that you complete all of your paint projects before you start wallpapering, such as painting the door frames, skirting boards or dado rails.
