Wallpapering is one of the most popular ways to refresh a room’s interior. But how do you do it neatly and without bubbles if you’re taking on the task yourself? In this article, we’ll explain how to properly hang wallpaper at home and avoid common mistakes — especially the appearance of air bubbles and uneven surfaces.
Why Do Bubbles Appear Under Wallpaper?
Bubbles usually form due to:
* Poor wall preparation
* Uneven glue application
* Incorrect placement of the wallpaper strip
* Use of low-quality materials
You can avoid all of these issues by following the correct process.
Wall Preparation — 70% of the Work
Before applying wallpaper, it’s crucial to prepare the walls:
1. Clean the surface — remove old wallpaper, dust, grease, or stains.
2. Even out the walls — fill in cracks, holes, and imperfections with putty.
3. Prime the surface — use acrylic primer to ensure better adhesion of the glue.
Choosing the Right Wallpaper and Adhesive
Vinyl and non-woven (fleece) wallpapers require special adhesives.
Always check the packaging to ensure the glue is suitable for your wallpaper type.
How to Hang Wallpaper Without Bubbles: Step-by-Step
Step 1: Mark the Wall
Start from a corner or a window. Use a level to draw a vertical line — this helps you align the first strip straight.
Step 2: Apply the Adhesive
For paper wallpaper, apply glue to both the wall and the strip.
For non-woven wallpaper, apply glue only to the wall.
Apply the adhesive evenly, avoiding gaps and puddles.
Step 3: Attach the Wallpaper
Gently press the strip onto the wall, aligning the top edge with your guideline.
Smooth the strip from the center outward using a rubber roller or a soft brush.
Step 4: Remove Air Bubbles
If bubbles appear:
Small ones often disappear after drying.
Large bubbles can be pricked with a needle and smoothed out with a roller.
Pro Tips
Avoid drafts during installation.
Keep the room temperature between 18–25°C (64–77°F).
Don’t let the wallpaper dry too quickly — it can cause peeling.
