How to Install a Sunstrip Banner on Your Car
Is the sunstrip you purchased from us matte black or matte white in colour? If yes, then it uses our ‘EZ Apply’ vinyl which is not suitable for wet installation, dry install only. All other colours of sunstrips are suitable for wet application if desired. 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 sunstrip, 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 windscreen to ensure the longevity of the decal.
- We also advise against using your wiper blades until the sunstrip 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.
Additional Weather Advice
Weather conditions and temperature play a big part in the installation and longevity of your sunstrip – with tried and tested results, technical data from our suppliers and firsthand experience, we’d like to offer further information to ensure your sunstrip 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 windscreen 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.
Dry Installation Method
windscreen prep (the most important part)
The first step is to prepare the windscren 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 to step 2, even if that means heating the glass with a hairdryer/heat gun or leaving to dry in the sun for a few minutes.
measure twice, fit once
Offer up the sunstrip to the glass, position and secure with masking tape. If you’re after perfect placement then a tape measure is your friend, measure and then measure again! Try to use key points on the windscreen that are symmetrical either side as guides to ensure you get the sunstrip level and centered.
Once you’re happy with your placement, go ahead and create a ‘hinge’ point vertically down the center of the sunstrip using masking tape.
One side at a time!
Peel the backing paper off one side, up to the center hinge point. Cut off the paper (DO NOT TEAR as this will leave paper particles that can get stuck or trapped under the vinyl and will create an irremovable air pocket, scissors are advised) near the hinge point. You’re now ready to apply one side.
Felt squeegee the banner to the glass working from the center hinge point outwards, applying reasonable pressure. If you get any air bubbles or creases, lift the vinyl up slightly and try again. Squeegee to the top and edge of the screen but don’t trim any excess yet. If you are using the EZ apply vinyl this can be very forgiving when removing any creases, air bubbles can be easily worked out of the vinyl.
This process is possible to achieve by yourself, just take your time. Otherwise we do recommend getting a friend to help you. In this instance, one holding the vinyl taught with both hands, the other using the squeegee to apply to the windscreen. Patience is key for best results.
Repeat for the other side
Now repeat the previous step for the other side. You’ll need to move the taped hinge point, remove the final half of backing paper and apply working center outwards.
Trim, safety first!
Before proceeding with this step, ensure you’ve squeegee’d the vinyl as much as possible up to the edge of the glass. Use a sharp craft knife to trim the excess vinyl at the edge, being careful not to cut yourself, or any rubber seals on the edge of your windscreen.
If there is application tape on the graphic (used to protect it in transit) this can now be removed by peeling it off at a right angle or parallel to the surface.
You can now step back and admire your handywork!
