For more material volume try a larger nozzle.

Adjusting the System

Sufficient fluid output (volume and pressure) and good 
atomization is a balance of atomozing 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:

Start sprayer with gun air flow valve completely 
open. If needed, slowly close gun air flow until you 
get a good spray pattern. Use minimum 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 60.9 cm) from surface. Use this 
spraying distance for most applications.

Select proper nozzle for your application. See 
Nozzle Selection Chart. Remember, the larger the 
nozzle, the heavier the pattern.

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.

To Get Less Material

Try one or a combination of these methods:

Open air valve.

Turn gun flow adjustment nut to decrease flow, 
counter-clockwise.

Use smaller nozzle.

To Get More Material

Try any one or a combination of these methods:

Close  air  valve.

Turn gun flow adjustment nut to increase flow, 
clockwise.

Use thinner material mixture.

Use a larger nozzle.

Preventing Material Surge at Gun Trigger

Pressure will build up in the system when you stop 
triggering the gun. To prevent material surge at initial 
gun triggering:

Point gun away from surface you are spraying when 
you first pull trigger. 

When you first start to spray, hold the gun away from 
the surface and gradually work your way closer to it.

Keep gun moving.

After you begin spraying, trigger the gun as little as 
possible. 

For Continuous Spraying

Use trigger lock to hold trigger open and reduce fatigue.

Check Material Consistency Periodically

Check and thin material as needed to maintain proper 
consistency. The material may thicken as it sits and slow 
down production. Agitate periodically.
