OPERATION - ADJUSTING THE SYSTEM
Sufficient fluid output (volume and pressure) and good atomization is 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:
To select correct nozzle for your applications, consider size of aggregate in material and coarseness
of spray pattern. Remember the larger the material nozzle, the larger the pattern.
Set material flow by closing air flow valve, and adjusting material flow regulator, while pulling trigger to
get the appropriate material flow.
Start spray system with air flow valve completely open. If needed, slowly close gun air flow valve
until you get the desired 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 48 in. (45.7 to 122 cm) from surface. Use this spray-
ing distance for most applications.
+ When spraying with a material nozzle only, overlap each stroke 50% in a circular motion.
+ When spraying with a material nozzle and WideTex disc, overlap each stroke 50% in a linear
motion.
Gun air flow is regulated using air flow valve located on the left side of the gun.
+ Opening air flow valve (counterclockwise) increases air flow through gun.
+ Closing air flow valve (clockwise) decreases air flow through gun.
For Less Material Flow
Try one or a combination of these methods:
Turn material flow reguator knob counterclockwise on gun to decrease material flow.
Use thicker material mixture.
Use smaller material nozzle.
Decrease needle travel.
For More Material Flow
Try one or a combination of these methods:
Turn material flow regulator knob clockwise on gun to increase material flow.
Use thinner material nozzle.
Use a larger material nozzle.
Increase needle travel.
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.

MIXING MATERIAL

(PRESSURIZED HOPPER GUN ONLY)
Step 1: Mix the material and water in a separate container. Dry
Mix: Carefully mix texture material and water according to
manufacturer instructions on the bag. Premix: Slowly add
approximately 2 to 6 quarts (1.9 to 5.7 liters) of water to a 5 gallon
(18.9 liter) bucket of premix.
Step 2: Agitate to mix, using a half-inch, vairable speed drill with
mixing paddle, to a smooth, lump-free consistency.
Step 3: Allow ceiling texture to set for at least 15 minutes. Then
remix prior to use.
