How to Mount a Plate Glass Mirror


From Snow White's stepmother to Alice in Wonderland, mirrors have long held a certain magic. Mixing glass and mirrors together makes for dramatic, clean-looking furniture. Fully mirrored walls make a small room seem larger. Follow the steps methodically and assemble the right tools to mount a plate glass mirror. Whenever you work with this medium, expect a magical result.

Things You'll Need

  • Mirror 3-by-6 foot by 1/4 inch
  • Drill
  • 1/4-inch drill bit
  • Rawl plugs for #8 countersunk screws, 1 1/2 inches long
  • Masking tape, 1 1/2 inches
  • 4 mirror hangers
  • 8 #8 screws, 1 1/2 inches long
  • Tube of mirror adhesive (optional)
  • Caulking gun (optional)
  • Measure down from the ceiling 7 feet precisely where you want the mirror to be hung. Move over 2 1/2 feet and measure down again. Join the two marks with a pencil. Measure down 6 feet and mark, repeat, then join the two marks.

  • Figure out where you want the bottom left-hand corner of the mirror to be. Measure in 3 inches from the left, then mark with a pencil. This is where the bottom center of the first clip will be. Measure and mark 3 inches in for the right side of the mirror. This will be the bottom center of the next clip.

  • Put one of the clips in place and mark the holes. Repeat with the next clip. Drill four holes and tap in the rawl plugs. Screw both clips in place. Put masking tape over the screws and inside the "J" part of the clip.

  • Put the mirror in the exact location. On each side of the mirror make a mark 6 inches down from the top. Take the mirror off the lower clips. On the right-hand side, mark the holes. Drill them out and tap in the rawl plugs. Hold the last clip in place and mark out the slider holes. Drill the holes closest to the inside of the mirror. Tap in the rawl plugs. Screw in just loose enough so the clip can slide from left to right.

  • Tape all the screws and "J" channels. Slide the top left clip to the left, then put the mirror in place. Tuck the last clip so it grips the mirror.

Tips & Warnings

  • Take everything slowly. Make sure there are no hammers around that could chip the mirror.
  • Even though the materials section lists mirror adhesive and a caulking gun, it is not necessary to glue the mirror to the wall. Some people like the added security, however.
