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 areas that are not to be sprayed. Keep in mind when
working that wind, for example, can transport paint mist over great
distances and cause damage.
• Test the spray gun on cardboard or a similar surface to find the
correct setting.
• When spraying, hold the spray gun in a horizontal position. Use the
flexible nozzle extension (special accessories) for spraying
upwards (e.g. a ceiling) or downwards (e.g. an unhinged door laid
on the floor).
Note: Begin spraying outside of the spray area and avoid
interruptions inside the spray area.
• Do not apply too much paint during one spraying operation. First
apply a thin layer and allow to dry briefly before applying a covering
layer. This is especially important with vertical surfaces to avoid
paint sags.
• The distance from the nozzle to the object to be sprayed depends
on the delivery rate. With a low delivery rate it is possible to go very
close to the object. This reduces the amount of spray mist.
• The spray gun should be worked as evenly as possible during the
spray operation. Accelerating or slowing down during the spray
operation causes an uneven spray pattern, spattering, dripping and
orange peel.
• 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
(Illus. 6, 7).
