Notice: This No-glue film is only for smooth glass. Can not fit to frosted glass or art glass.<br /><br /> <b>Installation</b><br /><br /> 1: Clean window (make sure your glass is clean and smooth); <br /> 2: Measure window and cut the film into required size;<br /> 3: Peel off the transparent backing film;<br /> 4: Wet both sides film. Wet glass (the more water, the better); <br /> 5: Paste the smooth side to glass;<br /> 6: Squeegee the film, squeegee away water and air bubbles;<br /> 7: Cut off excessive edges (leave a small gap about 2-3mm between the film and window to let water flow out).<br /><br /> <b>Q&A</b><br /><br /> Q1: Too hard to remove the backing protective film, is there any tricks?<br /> A1: Take two pieces of tape and place them on opposite sides of the same corner. Make sure you cover the corner completely but leave some tape on each side to grab onto. When you pull the tape apart the film and the backing should separate from each other easily.<br /><br /> Q2: Why my film does not stay?<br /> A2: Please don't forget to remove the transparent backing film, and then wet the window with clear water.<br /><br /> Q3: I have removed the back film and wet the widow, why still can not stay?<br /> A3: You may apply the wrong side. The film is divided into two layers, one side is smooth, and the other side is rough. Please tear it off and retry the smooth side to paste again.<br /><br /> Q4: There are a large number of small bubbles.<br /> A4: Too less water. Tear it down, spray a lot of water and paste it again. And then use a card to squeeze out all water and bubbles.<br /><br /> Q5: Why the edge of my window film begins to fell off?<br /> A5: (1) The edge of film is too close to the window. Please leave a small gap (about 2-3 mm) to let the water flow out so that the film can stick well.<br /> (2) Too cold in winter. Please use a hair dryer to soften the film before applying under cold weather (Heat Resistant up to 176℉).
