Applying your vinyl is simple if you follow some basic guidelines. The graphic generally comes in one piece and is sandwiched between a paper layer of transfer tape and a wax layer of backing. Start by removing the graphic from the packaging. 

If you're installing outside, wait for a nice day. Vinyl should never be applied in temperatures less than 50 degrees farenheit. The surface should be free of dirt, wax, and other window treatments for best results. Done properly, this job will last for over seven years.
 

1.To get the graphic on straight, start with a piece of tape on one corner. With the backing still on the graphic slap it up there where you think it should go. You can always move it if you don't like the position.

2."Hinge" the graphic along the top edge with a long piece of tape. Half of the tape should be on the transfer paper and half on the surface.

3.Now when you flip the graphic back to remove the wax paper, everything stays in place. Test it. Make sure it's not getting loose. 

4.Peel back the wax paper and expose the sticky side of the vinyl. 

5.Lay the vinyl close to the surface. It's called "pressure sensitive" vinyl which means that the harder it is pressed, the harder it sticks. Holding the free edge tautly, just off the surface , pull the squeegee across the center of the graphic to get a good center line of adhesion. 

6.Now you can lift one of the sides up and squeegee from the center line toward the edges. ALWAYS work from the center toward the edges. This avoids trapping air bubbles. 
 

7.Finish off the other half the same way (from the center to the edges, then from the middle to the top and bottom). If you started with a good centerline, the rest of the vinyl will fall into place naturally. 
 

8.Finish by removing the transfer paper. Wait several days and pop any bubbles with a pin and press out the air.
