A white reflection from a nearby light source can prevent a viewer from being able to see or fully appreciate a framed piece of artwork. Make precious artwork viewable without the visual distraction of a harsh glare by lining the glass with anti-reflective film. Transparent anti-reflective film is designed to scatter and diffuse reflected light, preventing it from entering the eye directly. This type of film is commonly used on retail shop windows to ensure visibility of displayed merchandise.
Line a work surface with a foam pad. Take apart the frame and lay the glass on top of the foam.
Clean both sides of the glass by polishing them with window cleaner.
Unroll a length of non-reflective film. Trace the glass or use a straightedge to mark the outline on the film, using a marker. Cut out the section with a craft knife.
Spray one side of the glass with window film application solution, covering the entire surface. The solution will activate the adhesive on the back of the film.
Remove the backing from the film. Line up one edge with the edge of the glass and lay the film onto the glass. The film will slide around a bit while the solution is still wet. Adjust the film as needed to fit onto the glass.
Spray the outside of the film with water. Smooth down and extrude excess solution from under the film, using a squeegee.
Leave the solution to dry, then place the glass back in the frame with the film side facing out.
