This self-adhesive, transparent blackboard film is ideal for creating blackboards for schools, kindergartens, offices or homes. It can be applied to glass partitions and does not take away any light. It isalways possible to wipe the blackboard film with a damp cloth and then rewriteit.

Please note: The film is not glass-carpet, but has a slightly rough surface. It can be printed with UV-curable inks and screen printing inks and written on with chalk or liquid chalk pens.

The board film is washable with water and has a removable adhesive. It is very dimensionally stable and resistant.

Included in delivery

You should definitely order the transfer concentrate, art. no. 020010 additionally. It makes the installation easier and leads to a better result. Alternatively, you can also use a pH-neutral cleaner. This must be pH-neutral to prevent streaks from forming together with the film adhesive!

Any offcuts are not included in the scope of delivery.

We cut each film to the exact millimetre according to the dimensions you enter. The cutting is free of charge. You can find detailed instructions on how to measure your panes here.

Alternatively, you can also cut your film by hand with a cutter knife. However, this requires a little manual skill, so you are usually better off using our free service.

In general, almost all 2D shapes can be produced. Many geometries (e.g. triangles, trapezoids, circles) can be ordered directly via the online shop. To do so, please click on the orange rectangle to the right of the article image. You can then choose between many different shapes.

For shapes that are not specified, please send us a small sketch (photo) in which you specify the side lengths, radii or angles. Please contact us for this purpose.

The window film adheres to all surfaces that are approximately as smooth as glass. When applying the film to plastic, please bear in mind that the adhesive may bond with the plastic, making it impossible to remove the film cleanly later.

You can keep your window pane clean as usual. The film should not be rubbed with sharp-edged objects (e.g. a brush).
You can find more information in our guide General care instructions for window films.

All window films can be removed without leaving any residue and without damaging the glass surface!
Below you will find detailed instructions on how to remove old window films.

Unfortunately, we do not currently offer foil printing and do not have any partner companies with whom we can realise foil printing.

Assembly instructions for Surface films (self-adhesive)

You will need the following items

Plastic bottle with hand sprayer, adhesive tape, paper towels (not included)
Transfer concentrate (not included)
Glass cleaner (not included) or commercially available glass cleaner
Installation squeegee and glass scraper blade (included free of charge in the delivery).

Installation tips

Two people should carry out the installation!
Do not install any film at temperatures on the installation side below +6° C.

Fill the spray bottle with 0.5 litres of water and add the transfer concentrate (30 ml) (enough for approx. 6 to 7 m² of glass surface).
Thoroughly clean the glass with commercial or our glass cleaner!
Remove all sticky particles (e.g. paint or fly dirt) preferably with the glass scraper blade. No dirt residues should remain on the glass!
The sandblasting foil consists of the mostly white backing paper and the actual sandblasting foil.
Now place the sandblasting foil with the view side down on the glass pane or similar. You are now looking at the back of the film.
Then carefully and slowly peel off the backing paper at as shallow an angle as possible until it is about halfway along the entire length of the film. Cut the backing paper and stick it back onto the sandblasting film with a gap of about 2 cm to the remaining backing paper.
Now hold the in place while the 2nd person starting from the corner, and at the same time spray the adhesive side of the that is now exposed with the liquid.
Afterwards, the glass pane (surface to be pasted) must be sprayed with the liquid. Do not be sparing with the liquid, the film and pane should be well wet.
Place the on the glass, the film should slide back and forth well, otherwise spray the glass again.
Now spray the other side of the as well, this will make it easier for you to work with the mounting squeegee.
Now press the liquid out evenly with the mounting squeegee from the centre to the right and to the left. Make sure that there is no residual water left under the film! Repeat this procedure several times to remove even invisible water residues. When doing this, wrap the supplied squeegee with a paper towel to avoid any scratches.
Carefully wipe the edges and the foil with a soft cloth. If necessary, press the edges again with the mounting squeegee.
Now let the dry for three days without touching it.
Wait two weeks before cleaning the film for the first time and never use hard objects (brush or blade) to clean it. Commercially available glass cleaners can be used.

FAQ`s about the installation

Films that are no larger than 1m² can be installed alone without any problems.
For larger pieces, it is recommended that two people carry out the installation. This makes it easier to handle the film and place it on the pane.

First, clean your windows really thoroughly with glass cleaner. Then go over the entire window pane again with our supplied glass scraper blade to remove any hard-core impurities on the pane (such as fly droppings). These fine stains are often invisible to the naked eye and you will be amazed at what the blade still removes.

In addition, do not lay the after peeling off (covers the adhesive side for transport) on the floor to get it wet. Rather, pull a table nearby to spray the film on. On the floor you will always stir up very fine dust particles, which will then settle on the adhesive side facing upwards. These dust particles can later show up on the pane under the , which is something to avoid.

Alternatively, you should at least use a pH-neutral cleaner. We do not recommend installation without any additive at all, which increases the gliding properties of the water!

We strongly advise against the use of water diluted with detergent. This can lead to streaking due to a reaction with the film adhesive.

No, this is not necessary as long as you have sprayed the adhesive side of the window film and your glass sufficiently wet. Due to the moisture, the adhesive has no adhesive effect, which makes it easy to move the film and position it precisely. It is even possible to remove the film from the glass again and reapply it.

The bubbles consist of residual liquid that was not pressed out from under the film when it was applied. Over time, these run down between the already drying film adhesive as far as they can under the film and collect in some places. The bubbles disappear by themselves when the remaining liquid diffuses through the film to the outside. Depending on the outside temperature and sunlight, this can take up to three or more weeks before the film fits like a second skin.

In any case, you should wait this time and do nothing. In most cases, the blisters disappear all by themselves!

The window film itself can be easily removed. To do this, detach one corner and fold it over directly. The film can then be removed from the glass at as flat an angle as possible.

It is possible that residues of the film adhesive remain in some places. These can be soaked with our adhesive remover or acetone and then removed again with a glass scraper or ceramic field scraper. You will find detailed instructions on how to remove window films on our homepage in the FAQ`s.
