To get bubbles out of old wallpaper, the primary method involves carefully making an incision and releasing the trapped air, then re-adhering the loosened section.
Bubbles in wallpaper often form over time due to improper installation, changes in temperature and humidity, or issues with the adhesive failing. Fixing them promptly can prevent the bubble from tearing or growing larger.
Tools You Will Need
Repairing wallpaper bubbles requires a few simple tools:
| Tool | Use |
|---|---|
| Razor Blade or | Making a small incision in the bubble. |
| X-Acto Knife | |
| Small Syringe | Injecting adhesive behind the wallpaper. |
| Wallpaper Adhesive | Re-sticking the lifted section. |
| Roller or Smoothing | Pressing out air and excess adhesive. |
| Tool (e.g., plastic | |
| smoother, clean rag) | |
| Damp Cloth or Sponge | Cleaning up excess adhesive. |
Step-by-Step Guide to Fixing Wallpaper Bubbles
Follow these steps to effectively remove bubbles from old wallpaper:
1. Prepare the Area
Ensure the area around the bubble is clean and dry. Protect the floor with a drop cloth if needed.
2. Make the Incision
Using a razor blade or X-acto knife, make a small incision in the wallpaper bubble. For smaller bubbles, a single slit might suffice. For larger bubbles, consider making an "X" or "+" shape incision to allow air to escape more easily and provide better access for adhesive. Make the cut following the pattern of the wallpaper if possible, to make it less noticeable.
3. Release the Air
Gently press down on the bubble to get all the air out from underneath it. Start pressing from the edges of the bubble and move towards the incision to force the trapped air out.
4. Add Adhesive
Once the air is out and the bubble is flattened, carefully lift the edges of the incision. Use a small syringe or a fine brush to apply wallpaper adhesive sparingly behind the lifted section of the wallpaper. Ensure the entire area that was previously bubbled is covered with a thin, even layer of adhesive.
5. Smooth the Bubble
After applying adhesive, gently press the wallpaper back down. Use a roller or smoothing tool to carefully press down on the repaired area, working from the center of the incision outwards to remove any remaining air pockets and excess adhesive.
6. Clean Up
Immediately wipe away any excess adhesive that squeezes out from the incision using a damp cloth or sponge. Be careful not to rub too hard, especially on older or fragile wallpaper.
Tips for Success
- Test First: If you're unsure about your wallpaper's durability or colorfastness, test the process (especially the cleaning step) in an inconspicuous area first.
- Multiple Cuts: For very large or stubborn bubbles, multiple small cuts might be more effective than one large one.
- Gentle Pressure: Always use gentle pressure when smoothing to avoid damaging the wallpaper, particularly if it's old or delicate.
- Allow Drying Time: Let the adhesive dry completely according to the product instructions before touching or cleaning the area further.
By following these steps, you can effectively address bubbles and restore the smooth finish of your old wallpaper.
