Examine the room carefully. Determine where your new mirror would look best. Talk to your family members and ask for their opinions. Once you glue the mirror to the wall, you can’t remove it without damaging both the mirror and the wall. Thus, choosing the right spot is crucial.
Ask a family member to hold the mirror against the wall in the spot you selected. Trace the mirror’s outline on the wall with a pencil.
Sand the area inside the lines with 40- to 60-grit sandpaper. This roughens the wall and helps the mirror adhere properly.
Wipe away the dust left behind after sanding with a clean, dry cloth. Wipe the back of the mirror with a separate cloth. Both surfaces must be completely free of dust to ensure that the mirror sticks to the wall properly.
Spread the mirror glue on the back of the mirror following the manufacturer’s directions.
Press the mirror firmly against the wall. Ask a friend or family member to tape the mirror in place with painter’s tape while you hold it.
Remove the painter’s tape after 48 hours.
