How to Remove the Protective Coating From Plexiglass


Plexiglass comes with a low-tack adhesive paper or film on both sides to protect it from getting scratched during storage and installation. The backing requires some patience to get started when removing, but usually comes off in one piece. When removing the protective coating from Plexiglass, never use sharp objects or abrasives. Although Plexiglass is durable and simpler to work with than actual glass, it scratches rather quickly.

Things You'll Need

  • Rubber jar opener pad
  • Separate one corner of the protective coating away from the Plexiglass sheet, using your thumb. Alternatively, you can use a rubber jar opener pad to help lift a corner of the film.

  • Grasp the raised corner of the film between your fingers and thumb.

  • Slowly pull the protective coating away from the Plexiglass. As you pull, grab the film close to the glass with your free hand and begin pulling from that point.

  • Release the corner and grab the film near the glass as you continue pulling with your other hand. Continue this back and forth grabbing of the film close to the Plexiglass until the film is completely off the piece. Removing the film in this manner helps to prevent it from tearing.

Tips & Warnings

  • If the Plexiglass is old and the paper difficult to remove, allow the Plexiglass to sit in direct sunlight for a few hours. You can also use products like GooGone to remove difficult paper backing. Use according to the directions on the bottle.
