Whether you live in an apartment where you can’t put holes in the walls or you simply don’t want to mar your walls with holes, hanging a heavy item without the use of screws, nails, picture hangers, wires or hooks isn’t difficult. The simplest way to mount a mirror without putting a hole in a wall is to use heavy-duty, double-sided mounting tape made specifically for such a job. It has quick-set adhesive formulated to remain bonded to a wall even if exposed to different temperatures or humidity levels.
Select a location to hang your mirror by holding it up on different areas of the wall. If possible, ask another person to hold the mirror while you stand on the other side of the room to judge the best spot for displaying it. Once you’ve decided on a spot, mark the wall lightly with a pencil along the top and bottom edges and/or corners of the mirror.
Place a level against the wall horizontally at the top pencil marks and tilt it up and down slightly until the bubble centres inside the glass tube in the level.
Draw a line lightly with your pencil along the edge of the level.
Lay a thick towel or blanket on a flat work surface and place the mirror on top of it, reflective side down.
Wipe the back of the mirror with a damp cloth to remove any dirt or debris sticking to the surface and wait 15 to 20 minutes for it to dry. In addition, wipe the wall down and wipe or air-dry it. If either surface has greasy or oily stains or other marks, wash the surfaces with mild detergent, rinse thoroughly with a damp cloth to remove any residue, then wipe or air-dry.
Affix strips of heavy-duty, double-sided, mirror-mounting tape to the back of the mirror along the sides, top and bottom.
Remove the paper backing from the double-sided tape strips, align the top of your mirror with the pencil line on the wall and press the mirror firmly against the wall.
Erase any visible pencil marks.
If you need to mount a heavy mirror without putting a hole in a wall, hire a professional mirror installer.
Never touch the adhesive surface with your fingers because you can transfer oil to the adhesive that can reduce its ability to bond to surfaces.
