Under reasonable weather conditions, film will dry flat with no blisters within 30 days when viewed under normal viewing conditions. Normal viewing conditions are viewing treated windows from a distance of ten feet from the room side, looking at a clear or uniformly overcast sky. Since a particle-free application isn’t possible, there may be small amounts of dust or grit caught between the film and glass.
There may also be a small amount of water left behind the film, particularly with the thicker films. Please be patient. Although in most cases this evaporates within 5-7 days, in rare cases this could take up to 90 days for the water to fully evaporate through the film.
