Paint patterns – errors, causes, and remedies
A faulty spray pattern is usually due to insufficient cleaning or dried paint
around the end of the nozzle or even in the nozzle itself. Lower these parts
into a solvent (paint thinner) to dissolve the dried paint and then remove it
with a brush or cloth.
Spray
pattern
Cause
Remedy
Dried paint on wing A
reduces the
air flow.
Stronger air flow
on wing B results
in more paint
on blocked side.
Dissolve the paint on
the wings using thinners
and blow dry the gun.
Do not poke
metal objects into
the nozzle jets.
Dried paint around
the nozzle jet C produces
an uneven
spray pattern,
as shown
on the left.
The same
pattern is
produced by
a loose air nozzle.
Unscrew the air nozzle
and wipe the paint nozzle
with a cloth soaked
in thinners.
Screw the air nozzle
back on.
“Two fried eggs”,
or a split pattern is usually
the result of:
1. Too high air pressure.
2. Too wide spray pattern
or too thin paint flow.
1. Reduce the air
pressure.
2. Turn the paint flow
adjuster to the left
and the spray pattern
adjuster to the right.
The width reduces
but the spray pattern
will be correct.
