How to make a faux window pane mirror
Open up any room in your home with a mirror. (woman in the mirror image by Lovrencg from

Tight living quarters such as apartments, condominiums and basement dwellings typically have low ceilings and are short on natural light and windows, making them feel cramped and cave-like. Mirrors quickly open up small spaces, but if you want to put a unique spin on this time-honoured solution, add faux window panes over the faces of your mirrors. This faux window pane mirror will hint at extra room without blaring its intent, making it a style-savvy update on a classic space-enhancing solution.

  1. 1

    Draw a grid formation across your mirror using the straight edge and dry erase marker. Arrange the grid to match your ideal faux window sections and mark the grid lines off with the tape; this will help you visualise the panes before you begin gluing.

  2. 2

    Measure the length of your grid’s columns and the lengths of the horizontal sections connecting them. Count the columns and horizontal sections so you'll know how many pieces to cut from the screen door moulding. Using the saw, cut out your columns and horizontal sections from the screen door moulding.

  3. 3

    Remove the tape. Mix your epoxy, following the package’s instructions. Glue the columns to the mirror with the epoxy, measuring again if necessary. Glue the connecting horizontal pieces between the columns. Tape all moulding down with more painter's tape while the epoxy cures, a process which often takes a day or more. Peel off the tape once the drying window has passed, according to your epoxy's packaging directions.

Tips and warnings

  • Age your mirrors by spraying the backs of them with nitric acid and allowing the acid to sit on the silvering for about 10 minutes before rinsing. Use caution with the acid; always wear a mask, preferably work outdoors and avoid skin, eye or mouth contact.
