Bubbles in your wallpaper make the wall look awful. Luckily there easy to fix!
1. For small bubbles (smaller than a quarter), grab a utility knife and cut a small slit right in the center. Use a syringe filled with liquid wallpaper adhesive to carefully inject a little adhesive behind the slit. Use a damp sponge to carefully smooth out the bubble and then let the area dry.
2. For a larger bubble (bigger than a quarter), use the utility knife to cut an “X” into the area. Carefully peel back the four corners, and apply wallpaper paste to the back of the paper. Grab a clean damp sponge and gently push each of the four corners back into place, smoothing as you go.
