Self-adhesive Contra Vision products can be removed from glass and other transparent substrates without traces of adhesive remaining when the products have been applied as recommended and removed within the time specified. If any adhesive does remain, it can be removed using proprietary cleaning products available in DIY stores such as B&Q/Home Depot or online.

One such product is De-Solv-it ‘Sticky Stuff’ Glue Remover. Use the product as directed paying particular attention with washing the window or panel after adhesive has been removed.

If it’s not possible to obtain a proprietary adhesive removal product, furniture polishes containing silicone, sprayed thickly on the remaining adhesive, will allow the residue to be scraped off after about ten minutes. Wash the window with soap and warm water after the residue is removed. Mr Sheen works well.

Please observe all precautionary advice and dispose of wipes and scrapers as required by local waste handling regulations and recommendations.

How to apply One-way vision window film

On this page we explain how to apply your new custom one-way vision window film (i.e., perforated window film).

Below you find instructions on how to apply your custom one-way vision window films. No water is needed.

• You apply the one-way vision window film to the front of the glass (on the outside of the window).
• Make sure to not apply your bespoke one-way vision window film in direct sunlight, make sure the temperature of the one-way vision window film, the window itself and the surrounding air is -ideally- around 12 to 18 degrees Celsius. When the temperature is above 18 degrees, we advise you to apply the window film during the early mornings or after sundown (during a time-period with the lowest temperature).
• Read the instructions supplied with your custom perforated window film. Always keep your window film flat so that is does not bend/fold.
• Clean the window and window frame thoroughly. Remove paint, grease and other dirt. This is especially important when the one-way vision window vinyl is applied outside, due to the holes in the material. Otherwise you will get issues.
• Also clean the surrounding area, like the window frame itself. If you are applying near the ceiling and/or the ground make sure they are also clean. Also be wear of flying insects.
• Use the supplied squeegee and card over the application-tape on the front of the window film to further increase the binding between the two.  Use a flat surface, like a table.
• Remove the backing paper. Carefully. The backing paper of one-way vision window film consists of

  two layers

   one transparent layer and one white layer with holes.
  • The front of the one-way vision window film contains the “honeycomb” structure with your print/design/photo on it. On top of the print is the whitish/yellowish transfer tape (which you only remove after installation. The back of the one-way vision window film contains the white “honeycomb” structure. This is the backing paper which you need to remove to expose the black adhesive layer.

• Apply the perforated window film with the application-tape to the window and position the window film at the preferred location.
• Use your supplied free squeegee. Start in the middle/centre of the window film and move horizontal with overlapping movements towards the edge of the window film. During which you hold the window film a couple centimetres (2 inches) above the window/mirror/surface itself.
• Allow the adhesive enough time to stick to the window. So that removing the application tape does not lift the one-way vision window vinyl from the surface/window/mirror. Remove the application tape after a couple of hours, 6 to 12 hours should be enough.
• If, when removing the application tape, you lift the one-way vision window vinyl from the window glass. Wait 24 to 48 hours before removing the application tape.
• The one-way vision window vinyl should be very easy to remove for the first two years after application. When the material is warm (apply heat with a heat gun) it is easier to remove and will leave less adhesive/glue behind.

Below you will find the instruction video for applying perforated printed frosted window film (Two-way vision window film). One-way vision window film is applied similarly to the two-way vision window film.
