Custom Window Decals

Step 1

Pick the right conditions. Apply the decal on a warm, dry day or in the garage. Excessive heat or cold affects the adhesive. Choose temperatures between 50 to 90 degrees Fahrenheit for car window decal application. 

Step 2

Clean the glass with mild soap and water. Use a lint-free cloth (such as microfiber or a lens cleaner for cameras or eyeglasses) to dry window to assure no lint or dust specks get on the decal.

Step 3

Assemble the right tools for the job: masking tape, squeegee (or credit card) and a knife.

Step 4

Put the decal where you want it. Put masking tape across the top of the decal to hold it to the window.

Step 5

Use the squeegee or credit card to press the backing. "Use overlapping strokes to apply, starting at the top center and working down and toward each edge." Use a smooth, slow stroke. Go over the entire backing.

Watch as you peel off the backing. If any of the decal lifts off the glass, press it back down with the knife. Press all of the backing again with the squeegee or credit card. Go slower and use more pressure. Remove the backing and the decal is set.
