Adjusting the System
Sufficient fluid output (volume and pressure)
and good atomization are a balance of
atomizing air, material thickness/material
flow and nozzle selection. Achieving the
correct balance for your application requires
experimentation to achieve desired results.
Keep in mind these important points when
adjusting gun:
• Select proper nozzle for your
application. See Nozzle Selection
Chart. Remember, the larger the
nozzle, the heavier the pattern.
• Start sprayer with gun air flow valve
completely open. Trigger sprayer gun.
If needed, slowly close gun air flow until
you get a good spray pattern. Use mini-
mum amount of air at spray gun to
achieve proper spray pattern and to
minimize bounce back.
+ Test spray pattern on cardboard.
Hold gun 18 to 24 in. (45.7 to 61 cm)
from surface. Use this spraying dis-
tance for most applications.
• Air and material flow adjustments are
made at the gun on all units.
+ Opening air valve increases air flow
through gun, which decreases texture
material flow through pump.
+ Closing air valve decreases air flow
through gun, which increases texture
material flow through pump.
