It is nearly impossible to get every drop of application solution from between the film and the window. Therefore, there is a drying time (“cure time”) for the film, when the remaining application solution evaporates. During this time, the film is still performing to its full solar control and safety capabilities, however it is common to see bubbles, haze, streaks and other visual defects in the film as it cures. This is completely normal, and these will disappear as the film dries out.The amount of time for the film to fully cure can vary drastically. If it is a dark solar control film on a hot summer day, the film can be completely cured within a few days. If it is a heavy gage safety film installed during the wintertime, it’s not uncommon for the curing process to last a few weeks. During the drying time, the bubbles and streaks are purely cosmetic.
