Bubbles in your wallpaper
make the wall look awful. Luckily there easy to fix!
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.
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.
