Tips for fitting the film

  • Two people should carry out the installation!
  • Do not install the film if the temperature on the installation side is below +6° C.

General installation instructions for self-adhesive window films
1. Fill the spray bottle with 0.5 litres of water and add the transfer concentrate (30 ml), or 5 drops of "FROSCH- (PH) Neutral Cleaner" (sufficient for approx. 6 to 7 m² of glass surface).
2. Thoroughly clean the glass pane or the surface to be glued with commercial or our glass cleaner! Remove all adhesive particles (e.g. paint or fly droppings), preferably with the glass scraper blade. No dirt residue should remain on the glass!
3. Separate the backing film or backing paper from the self-adhesive film you have ordered using adhesive strips that you stick to one corner on the front and back of the film and pull apart a little. Normally, the backing film (or backing paper) will remain attached to one adhesive strip and the actual self-adhesive film ordered will remain attached to the other adhesive strip. ATTENTION! Your film may have a (mostly white) backing paper OR a transparent backing film, which is very thin, transparent and really there ☺. These film carriers are non-adhesive and only serve to cover the adhesive side (as with a sticker, sticker).
4. Now hold the ordered film while the 2nd person peels off the backing film (the backing paper), starting from the corner, and at the same time sprays the exposed adhesive side with the liquid. Then the glass pane (surface to be pasted) must be sprayed with the liquid. Do not be sparing with the liquid, the film and the glass pane should be well wet.
5. Place the ordered film with the moistened adhesive side on the glass pane (surface to be covered). The film should slide back and forth well, otherwise spray the mounting surface again.
6. Now also spray the other side of the ordered film to make the work easier with the supplied mounting scraper (plastic scraper).
7. Now press out the liquid evenly with the squeegee, starting from the centre and working towards the side edges. Make sure that there is no residual water under the film! To avoid scratches, wrap the squeegee with a paper towel.
8. Carefully wipe the edges and the film with a soft cloth. If necessary, press the edges again with the mounting squeegee.
9. Now let the film dry for 3 days without touching it. Wait 2 weeks before cleaning the film for the first time and never use hard objects (brush or blade) for cleaning. Commercially available glass cleaners can be used.
10. Finished!

FAQ for film installation

How long do window films last?

Depending on the type of film, the installation side and the installation position, window films last for many years. Durabilities between 10 and 15 years are realistic. Please contact our customer service for a more precise estimate. We will be happy to assess your situation.

Difference between self-adhesive and self-adhesive films?

  • A self-adhesive window film has an adhesive back, similar to a self-adhesive stamp or sticker. With the help of the wafer-thin, transparent adhesive, the film sticks to the window pane after installation.
  • The self-adhesive film is adhesive-free and only adheres firmly to the window glass with its electrostatic back. The adhesive force is so great that it can even be used in damp rooms without any problems.

How do I care for my window film?


  • Do not clean the film for the first three weeks after it has been applied.
  • Commercially available glass cleaning agents can be used.
  • Clean the windows with soft cloths or a chamois leather.
  • Make sure that squeegees and all other cleaning utensils are clean.
  • Please clean film edges carefully.
  • Therefore, clean an externally installed film at short intervals so that the hard dirt particles cannot settle too firmly on the film surface.
  • In the case of externally laid films, coarse dust and dirt should be removed from the film with a very wet, soft chamois leather and sufficient clean water.


  1. Spray the window surface with the water - cleaner mixture.
  2. Wipe off water with a rubber wiper from top to bottom.
  3. Soak heavily soiled areas again and clean with soft chamois leather or sponge and plenty of water.
  4. Spray the window again with a water-cleaner mixture and wipe off with a squeegee from top to bottom.

Not recommended:

  • Do not use abrasive cleaning agents
  • Never clean the panes dry.
  • Do not use glass scrapers, razor blades or Scotch.
  • Do not clean with high-pressure cleaners or steam cleaners.
  • In general, the application of advertising stickers to the film coating is not recommended.
  • Always remember: The surface coating of the film is scratch-resistant, but not indestructible.

How to remove window film?

To remove a window film without leaving any residue and without damaging the glass, grasp it at one corner and then slowly pull it off at a wrong angle. In the case of adhesive films, the film can be warmed up with a hair dryer to dissolve the adhesive. Any adhesive residue after removing the window film can be easily removed with our adhesive residue remover.
