17. Spray Technique
The spray result depends heavily on the smoothness and cleanliness of the
i
surface to be sprayed. Therefore the surface should be carefully prepared and
kept free of dust.
The enclosed practice poster is ideal for familiarising yourself with operation
i
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.
Important: Start at the edge of the area to be sprayed. Start the spray
i
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.

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
i
regularly to make sure they do not get
blocked.
