How to Install a Windshield Banner
VINYL HOUZE · WINDSHIELD BANNER INSTALLATION GUIDE
Install your windshield banner
Your banner will be trimmed to fit your windshield.
This process works for solid-color, printed, and layered banners. The banner may extend past the side and top edges during installation. Apply it first, then trim it to the actual glass shape.
Helper, spray bottle, water, dish soap, measuring tape, low-tack tape, lint-free cloth, glass cleaner, felt squeegee, sharp blade, and cutting tape or a glass-safe guard.
1 · Check the fit
With the backing still on, hold the banner against the outside of the upper windshield. Decide where the lower edge should sit. Check the view from the driver seat and keep cameras, sensors, stickers, and sightlines clear.
2 · Clean the glass
Work out of heavy wind and direct hot sun. Clean the upper glass and corners thoroughly. Remove bonded debris from bare glass with a suitable scraper, then wipe away residue. The surface must be free of dust, wax, oil, and old adhesive.
3 · Find the center
Mark the center of the glass and banner with removable tape. Dry-fit the lower edge and check that the design looks level from inside. Have a helper hold the opposite end while you align it.

Apply with a center hinge
Position the banner first, then apply one half at a time.
Keep the paper backing in place while making the hinge. A helper can hold the loose end so the adhesive does not fold onto itself or touch dirt.
4 · Tape a center hinge
Align the center marks and lower edge one last time. Run a vertical strip of low-tack tape across the middle of the banner and onto the glass. This hinge holds the position while you work on the first half.
5 · Peel and apply one half
Fold one side back at the hinge. Peel its paper backing away and cut off only that loose backing. Hold the exposed vinyl just off the glass; squeegee it down from the center toward the outer edge in overlapping strokes.
6 · Repeat on the other side
Remove the hinge tape once the first half is secure. Peel the remaining backing and apply the second half from center outward. Resqueegee the full banner and edges. If it has transfer tape, wait until the vinyl bonds before removing it.

Trim and finish
Cut the excess to the actual windshield shape.
After the film has settled and holds its position, identify the overhang at both sides and above the curved top edge. Keep the blade off the rubber seal and paint.
7 · Check the overhang
The installed banner may extend past the left and right edges and above the top of the glass. Confirm the lower line is where you want it before cutting.
8 · Trim both sides
Use cutting tape or a glass-safe blade guard. Make light, controlled cuts through the vinyl only, then lift away each side offcut. Leave a small gap from the rubber or painted trim.
9 · Trim the curved top
Follow the actual top glass edge with protected, controlled cuts. Remove the top offcut, resqueegee every edge, and inspect for bubbles, lifting, or anything blocking the driver view.

Wet application option
Recommended for this banner when you want easier positioning and bubble removal.
After completing steps 1–3, use the spray mix below. Apply the wet method below instead of steps 4–6, then return to steps 7–9 for trimming.
A · Mist the glass and adhesive
Lightly mist the upper glass. Peel away the backing, then mist the exposed adhesive evenly so the banner can slide. Avoid puddles and keep the adhesive away from dirt.
B · Position and adjust
With a helper, place the banner on the outside glass. Match the center marks and adjust the lower edge. The sides and top can overhang; they will be trimmed after application.
C · Squeegee from the center
Hold the banner steady. Squeegee the liquid and trapped air from the center toward the open edges with firm, overlapping strokes. Wait until the banner holds position before trimming.

Make your application spray
A simple water and dish-soap mix for the optional wet method.
You can prepare the application spray with supplies you likely already have. Use a clean spray bottle and mix only what you need for the job.
Water + 1 drop of dish soap
Fill a clean 32 oz spray bottle with water, add one drop of liquid dish soap, close it, and gently mix.
How to use it
Spray a fine, even mist across the upper glass and exposed adhesive. Use enough to position the banner without leaving pools of fluid. Squeegee from the center outward until the solution is pushed to the edges.
After application
Give the adhesive time to take hold before removing any transfer tape. If your banner has transfer tape, peel it back slowly at a low angle. Trim the sides and curved top when the banner no longer shifts; resqueegee the cut edges.
Keep the bottle and squeegee clean. If you use a different banner material, check its supplied instructions before using a wet method.
