Proper surface preparation is the single most important phase of the installation because any lumps or cracks underneath will eventually show through even the thickest paper. When dealing with historical or uneven walls, experienced wallpaper hangers london will carefully scrape away loose debris, fill any structural gouges with high-grade compounds, and apply a specialized lining paper first. This multi-step process creates a perfectly smooth, stable, and chemically neutral substrate that guarantees flawless adhesion.
I am planning to decorate our living room with a premium, heavy-textured non-woven fabric wallpaper that I just purchased. However, the existing plaster walls underneath are in quite a poor state with visible hairline cracks, old flaky paint, and several rough patches from previous repairs. Do I need to hire a separate plasterer to completely skim coat the room before applying the paper, or can a skilled decorator fix these minor surface flaws during the standard preparation stage?
Skipping the prep stage or trying to paste over unstable paint is the main reason why wallpaper edges begin to curl or lift after just a few months. Lining paper acts as an incredible stabilizing layer that absorbs the tension of the top decorative paper as it dries, preventing seams from splitting open. Trusting a qualified specialist ensures that the base of your wall is technically sound, which preserves the life and appearance of your high-end design asset for years to come.
