The installation of a window film is not rocket science and is also easily possible for laypeople! It even becomes child's play if the right procedure is followed.

This is how you get your assembly to a perfect result

The correct procedure, which is valid for most self-adhesive foils, is presented in our assembly video. Take three minutes and your assembly can begin!

In 10 steps to the perfect slide assembly

You will need the following

  • Spray bottle, tape, paper towels (not included)
  • Transfer concentrate, item no. 020010 (not included in the scope of delivery) or alternatively dilute 0.5 liters of water with 5 drops of "FROSCH- (PH) neutral cleaner".
  • Glass cleaner, item no. 020210 (not included in the scope of delivery) or commercially available glass cleaner
  • Mounting set, item no. 010000 - assembly squeegee and glass scraper blade (included in delivery)

Tips for film installation

  • You should do the assembly with two people!
  • Do not mount a film if the temperature on the mounting side is below +6° C.

General assembly instructions for self-adhesive window films
1. Fill the spray bottle with 0.5 liters of water and add the transfer concentrate (30 ml) or 5 drops of "FROSCH- (PH) neutral cleaner" (sufficient for approx. 6 to 7 m² glass surface).
2. Thoroughly clean the glass pane or the surface to be glued with a commercially available glass cleaner or ours! It is best to remove all sticky particles (e.g. paint or fly droppings) with the glass scraper blade. There must be no dirt left on the glass!
3. Separate the backing film or backing paper from the ordered self-adhesive film using adhesive strips, which you stick to a corner on the front and back of the film and pull apart slightly. Normally, one remains Hang the carrier film (or the carrier paper) on the adhesive strip and the self-adhesive film actually ordered on the other adhesive strip. ATTENTION! Your film can come with a (usually white) backing paper OR a transparent backing film, which is very thin, see-through and really there ☺. These film backings are non-adhesive and only serve to cover the adhesive side (like a sticker, Stickers).
4. Now hold the foil you ordered while the second person peels off the backing foil (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 glued) must be sprayed with the liquid. Don't skimp on the liquid, the film and glass pane should be thoroughly wet.
5. Place the ordered foil with the moistened adhesive side on the glass pane (surface to be glued). The film should slide back and forth easily, otherwise spray the mounting surface again.
6. Now also spray the other side of the film you ordered to make your work easier with the assembly squeegee (plastic scraper) supplied.
7. Now use the assembly squeegee to squeeze out the liquid evenly, starting from the center and moving towards the edges. Make sure that there is no residual water under the film! To avoid possible scratches, you should wrap the assembly squeegee with a paper towel.
8. Carefully wipe the edges and foil with a soft cloth. If necessary, press down the edges again with the assembly squeegee.
9. Now let the slide dry for 3 days without touching it. Wait 2 weeks before cleaning the foil for the first time and never use hard objects (brush or blade) for cleaning. Commercial glass cleaners can be used.
10. Done!

Depending on the adhesive film, there are a few subtle differences that need to be taken into account. For this reason we have a suitable guide for each specific type.

Foil assembly FAQ

How long do window films last?

Depending on the type of film, the mounting side and the installation position, window films last for many years. So lifespans of between 10 and 15 years are realistic. To estimate a more accurate shelf life, please contact our customer service. We would be happy to assess your situation.

Difference between self-adhesive and self-adhesive films?

  • A self-adhesive window film has an adhesive backing, similar to a self-adhesive postage stamp or sticker. With the help of the wafer-thin, transparent adhesive, the film sticks to the pane after installation.
  • The self-adhesive foil film is adhesive-free and only sucks itself firmly onto the window glass with its electrostatic backing. 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?


  • The film must not be cleaned for the first three weeks after the film has been attached.
  • Commercially available glass cleaning agents can be used.
  • Clean the windows with a soft cloth or a chamois.
  • Make sure squeegees and all other cleaning supplies are clean.
  • Please clean the edges of the film gently.
  • You should therefore clean a film laid outside at short intervals so that the hard dirt particles cannot settle too firmly on the film surface.
  • In the case of foils laid outside, coarse dust and dirt should be removed from the foil with a very wet, soft chamois leather and sufficient clean water.


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

Not recommended:

  • Do not use abrasive cleaning products
  • Never clean the windows dry.
  • Do not use glass scrapers, razor blades or scotch.
  • Do not clean with high-pressure cleaners or steam jets.
  • In general, it is not recommended to attach advertising stickers to the film coating.
  • Always remember: the surface coating of the film is scratch-resistant, but not indestructible.

How to remove window film?

In order to remove a window film without leaving any residue and without damaging the glass, it is gripped at a corner and then slowly pulled off at a wrong angle. In the case of adhesive foils, the foil can be warmed up with a hair dryer beforehand in order to loosen the foil adhesive. Any adhesive residue after removing the window film can be easily removed with our Adhesive Residue Remover.
