In general, the smoother, cleaner, and more stable the wall, the better the result will be.
Unsuitable surfaces include:
-
Textured or relief walls: such as spachtelputz, decorative plaster, rough stucco, fiberglass wallpaper, or any wallpaper with texture. The wallpaper will not adhere properly, and the texture will remain visible.
-
Damp walls: for example in bathrooms or basements, where moisture can cause the wallpaper to loosen.
-
Highly absorbent surfaces: such as untreated plaster, lime, or concrete. These must always be primed first, otherwise the adhesive will be absorbed too quickly.
-
Damaged or powdery walls: loose paint, dust, or chalky surfaces prevent the wallpaper from sticking properly.
-
Wood or wooden panels without primer: these can expand or absorb the adhesive unevenly.
-
Plastic and glass surfaces: except for our peel and stick wallpaper. These surfaces are too smooth and non-absorbent, so the wallpaper cannot adhere.
-
Walls with latex or silicone paint: these are often too smooth or water-repellent, causing the glue to fail.
-
Old wallpaper layers: these should always be removed first for a smooth and long-lasting result.
For the best outcome, apply your wallpaper to smooth, clean, dry, and primed walls.
