– Avoid interruptions within the spray surface.
Guiding the spray gun evenly will provide uniform surface
quality.
Non-uniform clearance and spray angle lead to heavy forma-
tion of paint mist and thus to an uneven surface.
– End the spraying procedure outside the target area.
Never completely empty the container for the spray material
by spraying. If the suction tube is no longer immersed in the
spray material, the spray jet will be interrupted and this will
result in an inconsistent surface.
When coating material builds up on the nozzle and air cap,
clean both parts with the corresponding solvent.
