To safely hang a heavy mirror on drywall, create a French cleat and secure one part to the studs behind the drywall and one part to the back of the mirror. Alternatively, use toggle bolts as hollow-wall anchors if you are unable to secure the mirror to studs.Continue Reading
To create a French cleat, cut a 4-inch-wide strip of 3/4-inch plywood, and then bevel the edge at a 45-degree angle. Cut the strip into two equal lengths, and then attach one piece through the drywall into at least two studs, making sure the beveled edge faces upward. Attach the other piece to the mirror, with the bevel facing the other direction. Lock the beveled edges together to hang the mirror securely.
Use a toggle bolt and mounting screw if securing the mirror to studs is not an option. Drill a hole into the drywall the diameter of which is slightly larger than a folded toggle bolt, and then thread the mounting screw into the toggle bolt. Insert the bolt into the hole, and turn the screw until the head sticks out far enough to support a mirror wire, if you are not using an attached bracket. To install a bracket using a toggle bolt, push the mounting screw through the bracket-mounting hole before you screw it.Learn more about Interior Decorating
