Wallpaper installation is a fantastic way to transform any space, adding warmth, style, and personality to your room. However, to ensure that your wallpaper lasts and looks flawless, proper wall preparation is crucial. In this article, titled “The importance of properly preparing walls before wallpaper installation,” we’ll discuss why thorough preparation is essential and walk you through the necessary steps to achieve the best results.
First and foremost, make sure your walls are clean. 🧽
🟢 Remove dust, dirt, grease, stains, and any leftover wallpaper.
These surface contaminants can prevent the adhesive from sticking properly.
✅ Pro tip: Don’t forget corners and areas behind radiators — dirt loves to hide there!
Next, examine your walls for imperfections.
🟡 Fill in dents, chips, cracks, and small holes using filler or spackle.
This step helps create a smooth, even surface for flawless wallpaper adhesion.
🎯 Smooth surfaces = clean-looking wallpaper without bumps or air pockets.
After patching, it’s time to sand.
🟤 Lightly sand the entire surface to remove rough spots and excess filler.
This gives your wallpaper glue a better grip and ensures a seamless finish.
🧰 Important: Always wear a dust mask while sanding!
Now, let’s talk about priming — and no, you shouldn’t skip it.
⚪ Primer seals the wall and prevents excessive glue absorption.
It also helps wallpaper slide into place during installation and reduces the risk of peeling.
🧪 Especially crucial for porous walls like drywall or fresh plaster.
Before you begin wallpapering, use a level and straight edge to check wall alignment.
🔵 Uneven walls can make patterns look crooked.
Fix irregularities or choose wallpapers that disguise small flaws if perfect alignment is impossible.
🔍 Even a small slope can ruin the entire look!
When you take time to prepare the wall, the difference is clear:
🌟 Better adhesion = fewer air bubbles and no peeling.
🧱 Smooth look = professional-quality finish.
🕰️ Longer lifespan = wallpaper stays beautiful for years.
Skipping these steps often leads to early damage, poor aesthetics, and reinstallation headaches. 🙅♂️
Even though some brands claim “anyone can install,” the reality is different.
📌 Most wallpaper types — especially premium, thick, or patterned ones — require skill.
