Please note that in order to achieve a long-lasting bond, the surface must be thoroughly prepared. Please ensure the surface is properly cleaned and dry prior application. Our vinyl film adhesives are designed to create an excellent bond on clean, smooth, weather-resistant surfaces that are free of grease, wax and silicone.
The best way to clean the surface before installation is applying Isopropyl alcohol (on the surface) and wiping it with a clean cloth; other cleaning agents could attack the paint or reduce the adhesive strength of the film. Do not use ammonia-based cleaning products on the window as it will leave a residue (behind) that will prevent sticker from adhering well.
Some walls/doors are painted with finishes containing Teflon/Acrylic and such surfaces might be compromised with vinyl adhesion. All vinyls will also struggle to stick to any freshly painted surface.
