11. Spray Technique

•
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.
•
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.
