Installing a window decal correctly is a simple process that hinges on proper surface preparation and a patient application technique. The goal is to achieve a bubble-free, professional-looking result that lasts. You'll need the decal, a spray bottle with soapy water (a few drops of dish soap in water), a squeegee or credit card, and a microfiber cloth.
Start by thoroughly cleaning the window with isopropyl alcohol or glass cleaner to remove all dirt, grease, and debris. Any particles left on the glass will be visible under the decal. Once the glass is clean and completely dry, peel the backing paper off the decal. For larger decals, the "wet method" is highly recommended. Lightly mist the sticky side of the decal and the entire window surface with your soapy water solution. This creates a slippery layer that allows you to reposition the decal easily.
Carefully position the decal on the wet glass. Once it's perfectly aligned, use your squeegee to firmly push the water and air bubbles out from the center towards the edges. Start with light pressure and increase it as the water is expelled. For the final pass, use a firm, steady pressure to ensure full adhesion. Finally, slowly peel off the application tape at a 45-degree angle. If any small bubbles remain, they often disappear as the decal fully cures over 24-48 hours.
