Tools you need:
Ruler, Towel, Knife, Water spray bottle and Scraper (or a hard card instead).

Installation steps:
1. Clean the windows thoroughly to ensure that they are free of any dust or other impurities.
2. Cut the window film to the measured glass size. Leave an extra centimeter margin on both sides for later adjustment.
3. Apply two pieces of scotch tape on either side of one corner and peel off the back transparent protective film. Otherwise, the film may fall out of the window.
5. Spray water on both the target surface and the mounting side of the window film.
6. Apply the smooth surface of the window film to the glass. Once you've adjusted the position, use a scraper to push excess water and air bubbles out of the edges.
7.Trim excess edges.

Tips for Customers:
1.Please use a Hair Dryer to soften the window film(Especially the corner) before installation in cold winter, to make it easier to stick to the window.( heat resistance is under 176℉).
2.Only Fit for smooth surface without any dust or fiber, do not use on outside window or windows with cracks.
3.Clean the windows and spray lots of water is the key to keep window film static on the window. No Water bubble is the key to durable.
4.Peel off the film backing before you install and if this step is difficult for you, you can use some sticky tape to help you remove the film backing.
