17. Spray Technique
i
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.
i
The enclosed practice poster is ideal for familiarising yourself with operation
of the spray gun. After trying out the first spray coatings, it makes sense to
test it further on cardboard or a similar surface in order to find out the right
flow rate of paint and air for the best spray pattern.
•
Cover all surfaces not to be sprayed.
i
Important: Start at the edge of the area to be sprayed. Start the spray
movement first of all, and then press the trigger. Avoid interruptions
within the area to be sprayed.
•
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 10 - 30
cm, depending on the desired spray jet width.
Fig. 19 A:
CORRECT
Even distance to the
object.
Fig. 19 B:
INCORRECT
An uneven distance
will result in uneven paint
application.
•
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.

Important: Wipe off the nozzle and air cap
regularly to make sure they do not get
blocked.
