Peel and stick wallpaper has become a top choice for DIY home decorators in Australia. It’s easy to install, available in countless designs, and ideal for renters. But even the most stylish wallpaper can hit a snag if bubbles start to form beneath the surface.
Bubbling is one of the most common issues faced during application. While it may look frustrating, the good news is it’s completely fixable — and even preventable. This post will walk you through the causes, solutions, and best practices to ensure your wallpaper goes on smoothly and stays bubble-free.
What Causes Wallpaper Bubbles?
Bubbles form when air, dust, or moisture gets trapped between the wallpaper and the wall. Here are the most common reasons why bubbles appear:
-
Unclean surfaces: Dust or debris prevents proper adhesion.
-
Rapid application: Rushing the process can trap air.
-
Stretching the wallpaper: Pulling the material instead of letting it fall naturally.
-
Humidity and temperature: Especially in places like bathrooms or kitchens, moisture can cause lifting or bubbling.
High-moisture areas need extra attention. For moisture-resistant style options, explore bathroom wallpaper ideas that turn functional spaces into stylish retreats for practical inspiration.
How to Fix Bubbling Wallpaper
If bubbles appear after installation, don’t worry — there are a few simple ways to fix them without having to start over.
1. Use a Smoothing Tool
If the bubbles are small and recently formed:
-
Use a squeegee, wallpaper brush, or even a clean credit card.
-
Press gently from the center of the bubble toward the edge.
-
Repeat until the bubble flattens out.
2. Puncture and Release the Air
For stubborn or older bubbles:
-
Sterilize a fine needle or pin.
-
Puncture the center of the bubble carefully.
-
Press out the trapped air and smooth down the wallpaper.
This method works best when done gently and in well-lit conditions to avoid visible marks.
How to Prevent Bubbles Before They Start
Clean the Wall Thoroughly
Dust, grease, and residue prevent proper sticking. Use a damp cloth to clean the surface and let it dry fully before applying the wallpaper.
Measure and Align Correctly
Pre-cut panels to size, leaving a little extra at the top and bottom. Align carefully before sticking the top edge to ensure straight application.
Apply Slowly
Peel the backing down gradually while pressing the wallpaper onto the wall with a smoothing tool. Go inch by inch to prevent air pockets from forming.
Avoid Stretching the Material
Let the wallpaper fall naturally. Stretching may cause tension that leads to bubbling later.
Monitor Room Conditions
Install wallpaper in cool, dry conditions. High humidity can affect adhesive strength. This is especially important in kitchens. For design tips suited to this environment, check out why wallpaper is the hottest kitchen design trend right now.
Common DIY Mistakes That Lead to Bubbling
DIYers often overlook small details that lead to bubbling. According to this breakdown on why peel and stick wallpaper bubbles, the most common mistakes include:
-
Applying wallpaper on fresh paint before it cures
-
Using wallpaper on textured walls
-
Ignoring temperature and humidity levels
-
Repositioning the wallpaper too often during installation
Being aware of these missteps can save time and help maintain a flawless finish.
When to Replace Instead of Repair
Sometimes bubbling is persistent and widespread. If the wallpaper continues to lift or wrinkle after multiple fixes, it might be time to start fresh. Fortunately, removable wallpaper makes this easy.
Before reapplying:
-
Check for dampness or peeling paint underneath.
-
Let the surface dry and sand it smooth, if needed.
-
Always use wallpaper made for the specific room conditions.
Final Tips for Smooth Results
-
Use a level or laser guide when aligning the first panel.
-
Overlap slightly when matching patterns to avoid seams showing.
-
Use a helper for large pieces to ensure even application.
-
Trim edges with a sharp blade for a clean finish.

Bubbling doesn’t have to ruin your peel and stick wallpaper project. With proper prep, slow application, and the right conditions, you can avoid this common issue altogether. And if bubbles do show up, you now have the tools to fix them quickly and effectively.
