Allowing time for your window film to adhere to the glass is important. It is normal for a small amount of installation fluid to remain after a proper installation. This trapped liquid can cause a cloudy or hazy appearance and/or even small bubbles. These bubbles and the cloudy appearance will disappear.
But when? The thinnest of films in the best of weather will be cured as quickly as a week after installation, while thicker films and cold and cloudy weather may lengthen the curing time by as much as 30 to 60 days.
