Clean your window with isopropyl (rubbing) alcohol, available pretty much everywhere and allow the window to dry. Stay away from ammonia and other harsh chemicals since this will damage the window film.When installing on Plexiglass clean the glass well with denatured alcohol, not rubbing alcohol or soapy water and rinse.
Remove about 3″ to 12″ of backing paper by folding the liner down so it’s not in the way but still available to grab. You can also fully remove backing paper to install, whichever you feel more comfortable with.
Mist the clean window with water and also mist the adhesive back on the film as well. This will allow for easy repositioning and help remove large air bubbles.For non-adhesive/static film just mist the window.
Position the film in window.Squeegee down the exposed edge of the film starting from the center and working towards the edges. Brush from the center outward using overlapping 45 degree angled strokes.Slowly remove the backing paper and squeegee the graphic into place using the same 45 degree angle technique as above applying to the window as you go.
Once film is installed squeegee the whole window and film again to remove as much of the water and air bubbles as possible, squeegee from the center out at a 45 degree angle. If you get an air bubble, you can either lift the decal enough to release the air, or if the bubbles are not too large, you can pop them with a pin and squeegee the bubble toward the pin hole to squeeze out the air.
Don’t worry if there are some small air bubbles when done, most times they are unnoticeable.
