The application for Apple Watch Ultra 1/2/3 is the same as for the smartphone/tablet kit. Therefore, follow the smartphone/tablet instructions.

Reason: There is not enough Zcratch UV under the protective film. 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.

Reason: The device, the film and the hands have not been completely cleaned from all adhesive residue. Solution: • Clean the device and the film thoroughly with fresh handkerchiefs and isopropanol • Wash your hands with soap several times When cleaning the film (where the protective layer has already been removed) be very careful and work with fresh handkerchiefs! !DO NOT USE KITCHEN ROLL PAPER!

Solution: • Polish the PMMA film with acrylic glass polish or • Apply a new PMMA film Buy new protective films here: Films

Solution: • Heat the film briefly with a standard hair dryer • Clean with isopropanol after removing the PMMA protector When the film is heated, the adhesive loses its strength and becomes flexible.
