How to Remove Mirrors Mounted With Construction Adhesive

Large wall mirrors can be mounted using clips that are screwed into the wall, or by spreading construction adhesive on the back of the mirror. While both methods work equally well, the construction adhesive method poses a major problem if you later decide to remove the mirror. However, with a few special tools, you can remove the mirror without completely destroying the surface underneath.

Mirrors mounted with glue sometimes break when removed.
  1. Put on safety glasses and heavy work gloves before attempting to remove the mirror. These provide protection in case the mirror accidentally breaks during removal.
  2. Plug in a heat gun and turn it to the highest setting. Turn the heat gun on and aim it at the surface of the mirror, holding it at least 12 inches away. Move the heat gun over the surface of the entire mirror for approximately 1 to 2 minutes until the mirror is warm.
  3. Pick up the cutout out wire, with one handle in each of your hands. Widen your arms to pull the wire as tight as possible.
  4. Place the wire behind one corner of the mirror and work it back and forth until it slides under the corner.
  5. Move your arms in a side-to-side sawing motion to work the wire along the back of the mirror and cut through the construction adhesive. Stop when you reach halfway through.
  6. Ask another person to hold the loose section of the mirror to prevent it from falling. If the mirror is large, attach two large suction cups to it to help hold it. Continue cutting through the remainder of the construction adhesive until the mirror comes free from the wall.
