Spraying Technique
You can learn to spray paint as easily as you can learn to
paint with a brush or roller. You can get a professional
looking job in a safe manner by following the spray painting
tips below.
1. Heed all WARNINGS and CAUTIONS that are listed
on pages 3 thru 6 at the front of this manual. Take time out
now to reread them.
2. Avoid sharp bending and kinking of the paint hose. All
paint hoses should be kept clear of traffic and sharp cutting
edges or objects.
3. Use the lowest pressure possible when spraying. Too
much pressure shortens equipment life. It also causes
faster than normal wear on the spray tip.
4. Determine the best spraying distance (distance from
spray tip on the spray gun to the work). If the spray gun is
held too close to the work, you will have paint buildup that
will cause sags and runs. If the spray gun is held too far
from the work,
"fogging"
will result.
The correct distance should be about 10 to 12 inches. Keep
this distance for the entire length of the stroke. Of course,
the shape of some work surfaces will not permit this.
However, the same spraying distance should be kept
whenever possible.
5. Do not move the spray gun by flexing your wrist. The
result of this is shown in Figure 7. Rather, move the spray
gun with a smooth stroke of the entire arm and shoulder.
Maintain the same arm speed all the way through the
stroke. The result of this is shown in Figure 8.
