Solving Problems

Reason: There is too much Zcratch UV under the film or there is an overpressure that cannot be compensated.


  • Slightly lift up the protective glass -> push out the air and the Zcratch UV
  • -> this results in a thinner and more even adhesive layer

Reason: The device, the protector and the hands have not yet been completely cleaned from all adhesive residue.


  • Clean the device and the foil thoroughly with fresh handkerchiefs and rubbing alcohol
  • Wash your hands several times with soap


There are too many dust particles in the air.


  • Most of the dust particles can be removed later with the provided “Dust-Absorbers” 
  • The bathroom is often least affected by dust particles
