Paint volume adjustment
is incorrect for the air
volume (paint is too
thick).
Add thinners to paint
and re-fill.
Adjust air regulator to
increase pressure.
Over-painting.
Spray gun not clean,
resulting in needle valve
sticking.
Dismantle spray gun and
clean with thinner.
Too much paint.
Adjust the volume
regulator to reduce paint
volume. Try spraying two
thin coats of paint.
