Framing a mirror yourself may seem intimidating, but don’t let the idea of the unknown stand in your way. There are simple and inexpensive steps you can follow to successfully undertake your own mirror framing project and, as a result, spruce up the look of your existing mirror. Remember that purchasing a mirror-framing kit also is an option.
Measurements
Measure the mirror’s width and height before you move on to any other step. This can affect each of the other steps.
Picking out the pieces
Based on your desired design, select molding trim pieces (there are many options) that complement the room or area where the mirror hangs. Take note: the wider the trim pieces, the less mirror surface you will have left. Measure the four molding trim pieces to size based on the mirror measurements. Mark the measurements.
Cut, sand, wipe
Using a miter saw, cut a 45-degree angle on the ends of the trim pieces (a home improvement store can do this for you for a fee). The angled ends should match up together. Next, sand the cut ends with sandpaper until smooth. Wipe the edges with a cloth to remove the sandpaper dust.
Time to paint
With a paintbrush, paint or stain the molding trim. Allow it to dry and, using another paintbrush, apply a coat of polyurethane to the molding trim and allow it to dry. Note: polyurethane is available in different finishes - such as glossy, matte or satin.
Placement
Place several dots of epoxy adhesive onto the back of your first piece of trim, and place and press the molding trim onto the top of the mirror. Do this for the remaining three pieces, aligning the angled pieces together. Allow the pieces to dry.
Finally, the finishing touches
Apply a small amount of like-colored wood putty into the corner angles and smooth the putty into the trim pieces. Smooth the putty well and, to disguise any unwanted adhesive or seams, touch up the trim with paint.
