APPLYING VINYL TO Glass or Metal
You will need the following materials: Applicator (a credit card or plastic spatula works well), dishwashing detergent, water, clean rags.
Step 1: Prepare Your Surface
To remove any coating, soap, wax or dust on the surface you may clean it with water with a few drops of dish detergent, then rinse well and wipe with Rubbing Alcohol. Some cleaners will leave a residue.
Step 2: Prepare Your Vinyl
If your vinyl was shipped in a roll, unwrap it and let it lie flat with the transfer tape side up (so you can see the lettering or design) until it stays flat on its own. Rub it with your applicator to be sure the design is sticking well to the transfer tape. Rub from the center outward like rays of a sun.
Step 3: Position the Vinyl
The easiest way to line up the vinyl is to cut about an inch of the backing paper off on one side, or bend it back an inch. Position the vinyl where you would like it to be then press down the small area with exposed adhesive (or you could tape across the decal to be sure it is positioned right before cutting or folding the backing paper to expose the transfer tape. You can reposition the vinyl if the only thing touching the surface is the transfer tape. Once it looks good, slowly pull back on the backing paper as you smooth the transfer tape and vinyl onto the surface.
Step 4: Burnish your Design
The design should have placed just where you want it. Using an applicator, firmly rub the entire design from the center out, like rays of a sun. This is where you may need to take extra care to press the vinyl into any areas with texture.
Step 5: Remove Transfer Tape
When the design is firmly attached, slowly peel the transfer tape from the design. Start at a corner of the design and peel down at a 45 degree angle to the design. Don’t pull the transfer tape up, but pull it 180 degrees back on itself as you pull it off. If the design begins to lift up, put the transfer tape back and press firmly over the area and then try to remove it again.
Step 6: Burnish your Design Again
Remember the backing paper? To be sure the design is firmly in place you can place the backing paper over the design with the slick side (unprinted) down and burnish with your applicator tool over the paper and the design. With the transfer tape gone this keeps your applicator from scratching the vinyl.
Problem solving: Most vinyl sticks quickly and firmly to metal or glass. If there is a problem getting the design to attach, sometimes you can try heating it through the transfer tape with a hair dryer, letting it cool slightly, burnishing it as in Step 4 and then peeling the transfer tape off.
