Vinyl Installation 1Decal, Vinyl Lettering or Digital Prints

Vinyl lettering or Digital Prints can be applied to glass, wood, metal, drywall, and any other smooth surface. Vinyl lettering lasts up to eight years, depending on the quality.

1. Clean the surface. Remove the old vinyl lettering, if present, and then clean the surface with appropriate cleaner. Take precaution to avoid lint being left on the surface. For plastic or glass, a simple surface cleaner like glass cleaner is appropriate.

2. Make a hinge for the sign you want to apply. Apply masking tape to the top of the sign. Lift the sign upwards.

CAUTION! – Do not apply to the following: windshields, driver door window glass or passenger side door glass! Effects of condensation on window quality of perforated window films: rainfall, snowfall and or car washes can fill the small perforations and cause reduced vision until drying occurs. Consult your local laws regarding the application of window tint to vehicle glass.

Wet Weather Safety Tip

Rain can collect in the small holes and reduce vision. Use a towel to dry the surface of the perforated vinyl graphic for a clearer view prior to driving your vehicle.

  1. Prepare the Vehicle

Clean the outside glass surface which you will be applying the image to thoroughly with soap and water. Make sure that the glass surface is dry and residue free before applying your window image.

2. Position and Apply

When applying the window graphic, use masking tape strips to pre-position the image on the vehicle before removing the backing material. Carefully peel off adhesive backing from behind the image and apply from one edge and work to the opposite side, smoothing the image to prevent wrinkles. To remove any wrinkles, gently lift up the image to where the wrinkle is, smooth out the wrinkle with your hand, and continue applying.

If mounting a full window image you will have extra material to trim outside of the edge of your rear window glass. Trim the excess material with a razor blade or similar tool to complete the installation. The pressure sensitive adhesive bonds to the glass very well when first applied, but sets more firmly after a twenty-four (24) hour period. Avoid power car washes for the first week after application. For longer life avoid using window scrapers on this image. Treat this image as you would the painted surface of your car. Do not use abrasive cleaners on the image. Rear window mounted wiper blades will also cause premature wear of the image.

3. Care Tips

Special note for sliding glass rear window installations: If your vehicle is equipped with a sliding rear cab window, it is recommended that you wait one week before sliding the window. This will ensure that the pressure-sensitive adhesive is securely attached to the glass.

4. Car Washing

Avoid washing your window graphic for the first week after it is installed. After this time you can safely take your vehicle thru any commercial brush-type car wash.

5. High Pressure Power Washing

If you are using a do-it-yourself car wash, do not hold the wash wand closer than ten inches to the window mural surface. Use the same care that you would any pin striping or vinyl graphic on your vehicle and you should enjoy many years of use from your rear window graphic.
