The best way to avoid bubbles under your graphics is to use media with FLO Technology that eliminates bubbles and dramatically reduces installation times. In simple words FLO Technology means microscopical air channels in adhesive layer of the graphics. All our custom graphics are made using bubble free technology. In case you still find some bubbles under your freshly installed kit - no worries - it can be solved in few easy steps. For the best result you will need heat gun or hair dryer and needle or a razor blade. 1. Heat up the bubble (don't burn or overheat it). While heating up the air inside the bubble it will expand - thats's great. 2. When the vinyl is heated grab your needle or razor blade and make a tiny hole in the bubble so the air can rush out and vinyl can settle back down on plastic. 3. Use your fingers to push the remaining air out and press the vinyl down. Don't use any sharp tools to do this as you might damage the graphics.
