15. Setting the Amount of Air (Fig. 12)

Depending on the viscosity of the material to be sprayed and the finish of the object to be
coated, it may be advisable to vary the amount of air. Very low viscosity materials, such as
watery glazes do not have to be atomised with the maximum amount of air. In this case it
is advisable to reduce the amount of air and thus minimize the spray vapour.
This also applies for the use of the Detail and Corner&Reach spray attachment (accessory).

16. 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.
•
Cover all surfaces not to be sprayed.
•
Cover screw threads or similar parts of the target object.
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 5 - 15 cm, depending on the desired spray jet
width. When you are using interior wall paint, the distance should be about 20-30 cm
(approx. one stirring rod in length).

•
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.
"Cross spray" when using paint with a poor covering capacity or if the
i
surface is highly absorbent (Fig. 14).
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.

 higher amount of air
CORRECT Even distance to the object.
INCORRECT An uneven distance will result in uneven paint
application.
