Peel and stick wallpaper is a quick and stylish way to transform any space without the mess of traditional paste. But what if your wallpaper keeps falling off or just won't stick? You’re not alone — this is a common issue many DIYers face. In this guide, we’ll explain why peel and stick wallpaper is not sticking, how to fix it, and what you can do to prevent it from peeling in the future.
Why Is My Peel and Stick Wallpaper Falling Off?
There are several reasons why peel and stick wallpaper may come off after application — and most of them are easy to fix.
1. Poor Surface Preparation
This is the number one reason peel and stick wallpaper doesn't stick properly.
- Clean: Dust, grease, or even minor debris can prevent adhesion. Use a mild soap solution and let the surface dry completely.
- Dry: Never apply wallpaper on damp walls. Moisture weakens the adhesive.
- Smooth: Textured or uneven walls are the enemy of peel and stick wallpaper. Sand or skim coat if needed.
- Primed (Optional but Effective): A coat of wallpaper primer improves adhesion dramatically.
💡 Wallpaper not sticking to wall? It's almost always due to prep issues.
2. Wrong Wall Texture
Peel and stick wallpaper works best on flat, non-porous surfaces. Avoid applying on:
- Textured or bumpy walls
- Brick or concrete
- High-gloss or chalky paints
If you must apply it on a rough surface, use a liner paper or add extra adhesive.
3. Temperature and Humidity Problems
Extreme environmental conditions can cause peel and stick wallpaper to come off:
Cold Rooms: Adhesive doesn't activate well under 50°F (10°C)
High Humidity: Bathrooms, laundry rooms, and kitchens can cause peeling
Temperature Fluctuations: Rapid changes cause expansion and contraction
Tip: Let the wallpaper acclimate to room temperature for at least 24 hours before applying.
4. Poor Application Technique
Even high-quality wallpaper won’t stick well if applied incorrectly. Common mistakes:
- Not using a smoothing tool
- Rushing the process
- Not pressing firmly enough
How to apply it properly:
- Start from the top, working down
- Use a smoothing tool or soft cloth to remove bubbles
- Press edges and seams firmly
5. Low-Quality Wallpaper
Unfortunately, not all peel and stick wallpapers are created equal. Cheaper products often have weak adhesive or thin material that won’t hold up over time.
Recommendation: Choose trusted brands like CostaCover for better sticking power and durability.
How to Make Peel and Stick Wallpaper Stick Better
Try these expert tips to improve adhesion and keep your wallpaper from falling off again:
1. Use a Primer. Even if your wall looks clean, primer creates a better bonding surface.
2. Apply Additional Adhesive. You can reinforce problem areas (like corners or seams) with:
-
Wallpaper glue pens
-
Clear double-sided tape
-
Spray adhesive (for long-term hold)
3. Seal the Edges. Use clear silicone caulk or a bit of wallpaper glue along edges to prevent lifting.
4. Use a Heat Source. Use a hair dryer on low heat to gently warm the adhesive before reapplying — this can help reactivate the glue.
