  • Safe spraying (operator position, avoiding fall-outs etc.)
  • Use of remote control and robot maneuvering
  • Spraying angle and distance
  • Concrete adhesion and rebound
  • Pump and accelerator dosage
  • Preparation and washing rock surface
  • Spraying small and large areas
  • Thickness control and waste minimization
  • Systematic spraying
  • Time-limited spraying
  • Corner spraying

The practical module is specified to take 16-40 hours dependent on the skill level of the attendee. The attendee needs to finish all assignments to pass the practical module.
