Ensuring the wall is smooth, clean and completely dry is key for a successful installation. The surface should be free from old backing paper and contaminants such as dirt, dust, grease, mildew, ink stains; any of these can prevent adhesion taking place.
1. Remove nails / screws and fill in any cracks.
2. Switch off the electricity mains and remove any socket / switch covers.
3. Sand down any rough areas until smooth.
4. Use a sponge to clean the walls with warm water and mild soap, allow the walls to dry for a minimum of 24 hours.
5. Paint the wall a light uniform colour if it differs significantly from your wallpaper as dark patterns / colours may show through.
Important: Allow the wallpaper to acclimatise in the room it will be applied in for a minimum of 24 hours before application. To do this, take the wallpaper out of the packaging and slightly unravel.
Freshly painted walls should be left for 4 weeks before application, please refer to the paint manufacturers instructions for guidance. Follow general preparation instructions.
Porous surface (plaster, cement render):
Ensure old plaster is stable and free of mould and new plaster is completely dry. Cement render / concrete should be sanded smooth.
Seal the wall with a primer or diluted paste (also known as wall size). Allow the primer to completely absorb / dry, this will stop paste being absorbed during installation.
Spackle / fill in any screw holes and joints between plasterboards. Smooth and seal the wall with a primer or diluted paste (also known as wall size). Allow the primer to completely absorb / dry, this will stop paste being absorbed during installation.
