Mirrors help accentuate the size of any room. They reflect light, which makes a room brighter and appear larger. A mirror can be very heavy, and you must safely secure it when hanging a mirror up.
Using the stud finder, find the studs in the wall to hang a mirror. Check the back side of the mirror to see if it has picture wire attached or is bare. This will help you gauge where to put the screw or whether to use mirror clips.
Place the level directly over the two studs you found. Place the chalk liner slightly above the level, and snap it back to the wall. This will leave a light-coloured line for you to follow when attaching mirror mounts.
Using your drill, insert the screws or mirror mounts into the wall. If inserting a screw, leave about 1/2 inch of screw head sticking away from the wall so the picture wire can safely catch on to hold the mirror up. If using a mirror mount, there should be two small slotted hooks already on the mount for the wire to catch.
Mirror clips will often be used when hanging a mirror in the bathroom. You will need to apply an adhesive glue to the back of the mirror and press firmly against the wall. The mirror clips will secure the mirror.
