Make sure that you clean the area thoroughly with soap and water. Do not use window cleaner or similar products because it will leave a residue behind that will prevent the sticker from adhering well.
Prepare the sticker for application by firmly rubbing a credit card across the length of the sticker. This removes any air bubbles that may have formed and makes the sticker cling to the transfer tape.
Peel the paper backing off the sticker. If the sticker clings to the backing, slowly replace the paper backing and repeat the previous step.
Place the sticker onto the surface and rub it in place firmly with a squeegee or credit card. For best results, wait a few minutes before moving to the next step.
Slowly peel the backing paper off at an angle. Be careful not to pull the sticker off the surface. If sticker pulls away from the surface repeat the previous step.
