Spray gun settings vary
depending on the
manufacturer's model
and make. To assist, PPG
publishes gun charts for
its waterborne systems.
NOTE: For reference, see gun chart
technical bulletin DOX440 in Products
section of ppgrefinish.com and through
PaintManager program software.
Proper gun setup is important to
ensure the paint is applied evenly and
consistent results are achieved.
SETUP GUIDELINES
•
Ensure gauges and regulators are
designed for the gun being used in the
repair and are working properly.
•
Set air pressure 5–10 psi above
recommended PSI at the wall. (Air
pressure decreases from the wall to the
gun based on the length of air hose.)
•
Fine tune air pressure, fan control,
and fluid adjustments to deliver a
full wet, even pattern when tested
at 6–8" distance.
•
For small spot repairs, adjust gun
controls to create a smaller pattern
required for the repair.
TIPS:
A pattern too heavy on one side
will create wet/dry stripes.
A dirty air cap creates uneven patterns.
Too little air pressure creates a wide,
wet pattern.
Too much air pressure blows the
center out and creates a pattern heavy
on top and bottom, with very little fluid
in the center.
Too narrow a fan adjustment
concentrates all the fluid in too little
an area.
Too wide an open fan adjustment
can stretch the pattern too far, creating
dry spray.
