Prep the area you wish to apply the decal to. Spray it with cleaner and wipe it dry with paper towels.
Place the decal on the area and stick it on with two pieces of masking tape in each corner.
Fix the placement of the decal by using the leveler to ensure it is even.
Apply a strip of masking tape across the top edge of the decal to create a hinge. The masking tape should be sticking to the decal and to the area the decal is on, holding the decal in place.
Lift the decal from the bottom and remove the paper from underneath. Be careful and remove the paper slowly to ensure pieces of the decal do not stick to the paper you are removing.
Begin adhering the decal to the surface. The adhesive is now exposed and ready to stick to the surface you prepared. Using the squeegee, starting from the top of the decal, slowly begin sticking the decal to the surface. After you smooth out the top of the decal, start sticking the decal on from the top, center going outward on the decal, smoothing with the squeegee as you go. Smoothing out the surface from the middle to the outside of the decal will result in no air bubbles under the decal.
Remove the masking tape.
Remove the outside paper from the decal. Do this slowly and carefully, starting from one of the top corners so you do not remove the decal from the surface.
