Spray Technique
●
The spray result depends heavily on the smoothness and cleanliness of the sur-
face 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.
● Correct (Fig. 11 a) Be sure to hold the spray gun at an even distance of
approx. 5 - 15 cm to the target object.
●
Incorrect (Fig. 11 b) · Heavy spray fog build-up, uneven surface quality.
