Please ensure the print is perfectly dry. The printed material should be left to dry at least 48 hours prior to lamination or transport. If the printed graphics is likely to be exposed to corrosive liquids, smoke, fumes, highly polluted areas or if there is a likelihood of scratching or friction or to ensure longer durability, it is strongly recommended to laminate the prints with pressure sensitive optical clear protective material: ProCover Film. For vehicle graphics it is recommended to use a 1 cm overlap of the lamination film versus the Perforated window film or to seal off all sides of the window graphics with clear silicone to avoid water infiltration.
