How to Remove Wallpaper Bubbles

Decorating with wallpaper is a fun way to give a room some design, and a relatively easy DIY project. But sometimes things go a bit awry. A common mishap with newly installed wallpaper is the formation of pesky wallpaper bubbles. Fret not! In just a few simple steps, you can easily fix your walls’ blemishes.

What Causes Air Bubbles in Wallpaper?

Bubbles in wallpaper most often begin with wallpaper installation—specifically when wallpaper fails to properly bond with the wall surface. It can happen soon after installing the wallpaper or over time.

Another reason air bubbles can occur is not allowing the wallpaper panels to “book”. To book, paste must be applied onto the wallpaper panels, allowing it to absorb the adhesive and expand. If the “booking” time is insufficient, the wallcovering will expand on the wall, leading to the creation of air bubbles. Air bubbles in wallpaper may also indicate an imperfection in the wall surface, like dirt, paint chips, or holes.

By ensuring you have a clean and smooth wall surface and allowing sufficient “booking” time for wallpaper panels, you can prevent bubbling wallpaper from occurring.

How to Fix Bubbling Wallpaper

Fortunately, wallpaper bubbles and blisters are easy to fix. To remove wallpaper bubbles, you will need the following:

  • Razor Blade or X-acto Knife
  • Sponge
  • Tweezers
  • Optional: Small Specialty Syringe (for reapplying paste)

1. Cut the bubble

Using a razor blade or X-acto knife, make a small incision in the wallpaper bubble.

2. Push out air and remove any solid material

Gently press down on the bubble to get all the air out from underneath it. Use the tweezers to carefully open up the incision and remove any problem material (like dirt or paint chips) from inside the wallpaper bubble.

3. Use the syringe to apply adhesive

Load a syringe with wallpaper glue and insert it into the incision. Apply a generous amount of glue, but be careful to not oversaturate the area.

If you have just hung the wallpaper, press down on the bubble before applying more glue. If it does not hold, then use the syringe to add more.

4. Smooth Out the Bubble

Flatten the paper against the wall using light pressure. Smooth out the bubble with a damp sponge. Wipe off any excess glue and allow the wallpaper repair to dry.

Repeat this process on other wallpaper bubbles as necessary. Once completed, you can sit back and admire a job well done!
