When spraying, the Spray Gun should be held
square to the surface being painted, at a distance
of 8 to 12 inches (20 - 30cm) from the surface.
Keep the gun parallel to the surface being sprayed,
starting the stroke before pulling the trigger, and
releasing the trigger before ending the stroke.
Overlap each stroke over the preceding stroke to
obtain an even finish. The paint cover should be
even and wet when spraying.
If the Spray Gun is too far from the surface, or the
paint is too thin, the paint will dry before hitting the
work, resulting in a rough, sandy finish. Allowing
overspray to fall on a finished area will also result in
a rough finish. Too much paint feed or holding the
gun too close to the work will lead to runs and
sagging.
Let your arm control the Spray Gun, NOT your wrist.
Spraying Technique
Helpful Hints
1.
Evenly control the speed of movement of the spray gun. A fast speed will
give a thin coat and a slow speed will give a heavy coat.
2.
Only apply one coat at a time. If a further coat is required follow the paint
manufacturers instructions for drying times.
3.
If spraying small areas or objects keep the output setting low as this will avoid
excessive use of paint and will minimise overspray.
4.
When spraying large areas or objects, it is best to
use a criss-cross pattern, either from left to right
then up or down or vice-versa. This will ensure
maximum coverage
5.
Avoid stopping and starting when spraying as this
can lead to too much or not enough material on
a surface.
6.
To ensure edges are covered, commence spraying just to the side of area
being sprayed, continue and do not stop until the spray has gone past the
opposite edge.
