If you are installing vinyl onto glass, you may encounter a few obstacles. Some glass may be coated with a substrate such as silicon, which makes adhesion very difficult to achieve. Removing vinyl from glass can be tricky as well.  If you use resistance or anti-reflection film, you might find it tough to separate it from the glass.  If the window is tinted, you run a high risk of damaging the tint.

Here are a few steps to prevent problems during and after vinyl application:

  • Do not apply vinyl to glass when the air surface temperature is below 40°.
  • Clean the glass thoroughly before installing vinyl. Be sure to remove any oil and silica from the surface.  We do not recommend using Windex as this can leave a film on the surface which can prevent adhesion.  We recommend using Isopropyl Alcohol.
  • Do not use wet application when working with perforated vinyl. This could cause moisture to become trapped in the holes and make it difficult to see through the graphic. Dry application is the only option for perforated vinyl.
  • For perforated vinyl, use an optically clear laminate to ensure durability. This will protect the film and prevent dust, dirt, and water from collecting in the perforations. You must use “optically clear” laminate or else it will look hazy from the inside.
  • Avoid the use of dark graphics on window fronts. Dark vinyl will absorb sunlight and prevent the glass from releasing heat. It’s even been documented that glass may explode under the intensity of the heat.
  • Tack down the film in the center of the glass, and cut the graphic to shape. You can flip the vinyl up using masking tape as a hinge. Then remove the graphic’s liner.
  • Flip the vinyl back and begin to apply pressure to the film to establish contact to the glass. Slowly remove the liner as you go.
  • Start your squeegee action from the middle of the graphic, moving from one side to the other. Continue the process, progressing from the top of the graphic down with overlapping strokes. Remove the liner as you go.

If you are applying two panels that are designed to meet side by side on the glass surface, you need to carefully trim the images to let the panels meet and form a seam. Never overlap panels and trim before application. Refrain from cutting the ggglagraphic when it is already in place.  This will scratch the glass surface.
