Window Graphic Removal

Window Graphic Removal Removing a window graphic is much different
than removing graphics from other substrates. Most substrates, you can use a lot of heat,
you can pull as hard as you want, and you´re not going to break anything. Glass can withstand temperatures upwards of 2000C when heated evenly. But if you heat
just one area of a pane of glass, as little as a 150C, the glass is likely to shatter. The usual heat sources, found in most sign shops, are heat guns and torches that have
an average upper heat range of 1000C to 2000C. In less than 3 seconds, the glass could be
breaking. Another common reason for glass to break is
the incorrect use of force. If you are removing a large graphic from a long span of glass,
pulling as hard as you can in the middle can bend the glass beyond its flexible boundaries. Vinyl sticking to glass has a much higher bond than on other substrates, so it´s always
easier to remove it in small pieces. I use a liner cutting tool to score the vinyl without cutting the glass. Try to score with straight lines. Evenly cut sections remove much more consistently than odd-shaped pieces. By scoring the graphic several times, you
can pull the vinyl off the window as hard as you´d like, without the risk of breaking
the glass. If there´s a little adhesive residue left
over, clean the window with a mild solvent like IPA or mineral spirits. Using little or no heat and the sectional removal technique, window graphics can be removed quickly, but most importantly – safely.
