13. Spray Technique

•
The spray result depends heavily on the smoothness and cleanliness of the surface to
be sprayed. Therefore the surface should be carefully prepared and kept free of dust.
•
Cover all surfaces not to be sprayed.
•
Cover screw threads or similar parts of the target object.
•
It is advisable to test the spray gun on cardboard or a similar surface to find the
correct setting.
Important: Begin spraying outside of the target area and avoid interruptions inside
the target area.
The spray movement should come from the arm, not just from the wrist. This ensures
that a uniform distance is maintained between the spray gun and the spray surface
during the spray operation. Select a distance of 5 - 15 cm, depending on the desired
spray jet width.

Fig. 9 b: INCORRECT Uneven distance causes uneven coating.
•
Move the spray gun evenly cross-wise or up-and-down, depending on the spray
pattern setting.
•
An even movement of the spray gun results in an even surface quality.
•
When coating material builds up on the nozzle and air cap, clean both parts with a
solvent or water.
Danger of injury! Never pull the trigger guard while adjusting
the air cap.
