Proper wall and ceiling preparation is the key to a flawless wallpaper finish. Learn how to clean, prime and smooth your surfaces for the best results.
To ensure your wallpaper looks beautiful and lasts for many years, careful preparation of the walls and ceilings is essential. Please follow these steps:
1. Clean the surface
Make sure the surfaces are smooth, clean, free of grease and dust, and completely dry.
Any remains of old wallpaper should be removed without residue.
2. Apply primer
To equalize absorbency and stabilize sandy plaster substrates, we recommend applying a water-based primer (deep primer) before wallpapering.
3. Use wallpaper primer
To prevent colour irregularities from showing through the wallpaper, apply a pigmented wallpaper primer.
-
Standard wallpaper primer is white.
-
For wallpapers in bold colours, it is advisable to tint the primer with colourants beforehand. This way, even slightly opened seams will remain almost invisible.
4. Alternative: lining paper
Instead of wallpaper primer, you may also use a lining paper (smooth underlay wallpaper), which provides an evenly absorbent surface.
5. Level out uneven surfaces
On very uneven walls or challenging substrates such as unplastered masonry, textured plaster or wood, the entire surface should first be filled and levelled.
-
Fill holes or cracks with a gypsum-based filler.
-
Smooth out rough areas and irregularities carefully.
👉 With this preparation, you create the perfect foundation for your wallpaper to truly unfold its full effect.
