The main cause of vinyl failure is due to poor initial adhesion. To ensure correction initial adhesion, make sure the surfaces has been correctly cleaned, using detergent then isopropanol. In cold or damp conditions initial adhesion can be a problem, and the result is that graphics, particlarly fine serifs, can lift off vehicles or glass more easily. To avoid this, try to apply dry in cold conditions, or apply mild heat to the vinyl after application, to activate the adhesive.
Calendered films can lift from recesses if they have been stressed during application. Calendered films should be laid unstressed into recesses.
