How to Install a Windshield Banner on Your Car




Any oil slick material is not suitable for wet installation, dry install only. All other colours of banners are suitable for wet application. The following is provided as a guide only, if in doubt we highly recommend seeking professional installation – we are unable to issue replacements for errors caused by the improper installation or use of the product.

  • Do not install if the atmospheric temperature is below 10°C/59°F.
  • Do not install if the atmospheric temperature is above 25°C/77°F.
  • Once you’ve installed the windshield banner, we advise against getting it wet for at least 48 hours. It’s best to allow maximum time for the adhesive to cure to the windshield to ensure the longevity of the decal.
  • We also advise against using your wiper blades until the banner has had time to fully adhere to the surface. Once it has fully cured, it’s very unlikely that your wiper blade will remove it assuming it was properly installed following our steps below.




Weather conditions and temperature play a big part in the installation and longevity of your banner – with tried and tested results, technical data from our suppliers and firsthand experience, we’d like to offer further information to ensure your banner is installed correctly and stands the test of time. We understand and recognize that not all locations will have the same weather conditions and temperatures, so please take into account your location and decide when is best to install.

  • Our recommended atmospheric temperature range for installation is between 15°C/59°F – 25°C/77°F.
  • For colder seasons and areas, do not install if the atmospheric temperature is below 10°C/50°F as this can cause the vinyl to become brittle and harder to work with. The cold temperature will also weaken the bond between the adhesive and your windscreen causing adhesion issues, if it’s too cold for the adhesive to activate and cure there’s a high probability it will begin to peel prematurely. Also keep in mind that the adhesive takes at least 24 hours hours to cure, so if the temperature drops overnight or gets damp before fully set, it may peel.
  • For hotter seasons and areas, do not install if the atmospheric temperature is above 25°C/77°F as this can cause the vinyl to become aggressive and difficult to work with. The warm temperature will cause the vinyl to become more soft and ‘fluid like’ which in turn can cause tears, creases and rips to occur more easily.
  • Do not install in direct sunlight. Find shade where possible and allow your windshield to cool down if it’s been sat in direct sunlight for some time.
  • Do not install in extreme weather conditions. This includes high winds, heatwaves, sub-zero temperatures, rain etc.



The first step is to prepare the windshield so that no dirt, dust, grease or residue remains. Be sure to completely remove any waxes, gloss protectors or enhancers before you install, as these will all prevent adhesion to the surface. We strongly recommend using a clean microfibre cloth and isopropyl rubbing alcohol to prep glass surfaces. If you’re at a pinch then soap and hot water can be used (be sure to rinse the surface thoroughly after with clean water, if you do not clean it off adequately you will leave a layer of soap residue that will affect adhesion). Do not use any dedicated glass cleaners as most of these are ammonia-based and leave a slick coating on the surface, causing the decal to peel, and will out-gas causing bubbles.

Ensure the surface is completely dry before continuing, even if that means heating the glass with a hairdryer/heat gun or leaving to dry in the sun for a few minutes.
