A plastic stained glass window sounds like an oxymoron, but you can create a plastic window that looks like stained glass if you have the right materials. Stained glass paint is designed to work with a slick acrylic or glass surface. When it’s dry, stained glass paint has the translucent quality of real stained glass. You can find stained glass paint in an array of colors.
Purchase a clear acrylic sheet to fit the desired size of your stained glass window. You can find this plastic material at your local home improvement store.
Select a template of the image you’d like to paint on your window. Enlarge the template, if necessary, to fit the sheet of plastic. You may wish to draw your window design freehand. If so, skip the template and create the outline of your design onto the face of the plastic with leading strips.
Tape the template face up beneath the plastic sheet. Outline the design with strips of self-adhesive leading. You can use liquid leading, but you’ll need to let it dry overnight before you paint your stained glass window.
Fill in the colors of your design with stained glass paint. Squeeze the paint directly from the bottle onto the plastic sheet. The paint will flow between the leading strips.
Look for bubbles in the paint. Pop them with a toothpick. Air bubbles are a common occurrence and will be visible when the paint is dry. Allow the stained glass paint to dry before you tilt the plastic window upright.
Measure and cut a strip of decorative molding to fit each side of the plastic stained glass window. You can cut the molding to abut at the corners or you can create mitered corners. Attach the strips to the edge of the plastic window with construction adhesive.
