14. Spray Technique

•
Cover all surfaces not to be sprayed.
The enclosed practice poster is ideal for familiarising yourself with
operation of the spray gun. After these initial spray attempts it is a
i
good idea to perform a spray test on cardboard or a similar surface,
in order to determine the material quantity required to achieve an
optimal spray pattern.
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 20-30 cm, depending on the desired
spray jet width.
Fig. 7 A: CORRECT Even distance to the object.
Fig. 7 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.
•
If nozzle and air cap are soiled, clean both parts with water and solvent.
"Cross spray" when using paint with a poor covering capacity or if the
i
surface is highly absorbent (Fig. 8).
Interior wall paint in strong colour shades should be applied at least twice
i
(allow first paint coat to dry first). This will ensure good coverage.
Important: Wipe off the nozzle and air cap regularly
i
to make sure they do not get blocked.
