Due to the film's own surface tension, a negative pressure forms, which is why the film draws air. Solution: • Use more adhesive • Shorter lay-time when turned around • After laying and turning back, do not harden directly – wait 30–60 seconds and check whether the film draws air • Do not turn the device over from Apple Watch 7 onwards If the application has already been done and the adhesive has not hardened, you can lift the protector and refill some Zcratch UV. ### The film draws heavy grease stains after the application?
