BYD, roof wrapping in North District

BYD, roof wrapping in North District.
Roof wrapping performs not only decorative functions, but also enhances the protection of the roof from damage, for example, from fractures and dirt. Before wrapping the roof, various contaminants are removed from it, especially from hard-to-reach places. Then the roof is polished with abrasive clay. After that, the rubber seals and technological gaps are purged with compressed air and the remaining water and dirt are removed. A film is applied to the prepared surface covered with water, which was previously sprayed with a spray gun or by dry method. In the first case, after pasting, the film is leveled and the remaining water is removed. In case of the dry method, either a film with channels for air removal is used, or air bubbles disappear after some time after pasting.
