How to Mount a Large Mirror to a Picture Frame

Disassemble the picture frame. Remove the cardboard, picture and glass from the frame.

Decorate the picture frame, if desired. Attach molding and give the picture frame a new coat of paint before mounting the mirror glass. Allow the paint to dry.

Lay the picture frame on a flat surface, the backside of the frame facing up. Plug in and heat a hot glue gun. Place hot glue around the perimeter of the frame, where the glass rests on the frame.

Set the mirror inside the frame, mirror-side down. Press down on the glass to secure. Use a heavy duty tape to tape the backside of the mirror to the frame.

Use a stud finder to find the studs in the walls. Place picture hangers built for heavy mirrors or pictures on the walls where the studs are located.

Replace the hardware on the picture frame, to hold the weight of the mirror. Measure the gap between the picture hangers on the wall before attaching the D-rings. Use the measurement to attach the D-rings on the frame.
