Mixing Material
Mixing Material
Correct material mixture is essential. The pump
will not operate if the mixture is too thick.
Mix the material in a separate container before
pouring it into hopper.
Use Material Thickness Gauge to determine mixture is thin enough to spray.
*The Material Thickness Gauge will only determine if the material is thin enough to pass through
the pump. For some applications or for higher
speed spraying, your mixture may need to be thinner.
Dry Mix - 40 lb (18 kg) bag
For best results do not use partial bags of material.
1. Carefully mix texture material and water according
to manufacturer instructions on bag.
5. Observe the ball on the material. When the material
is thin enough to spray the ball will sink completely
into the mixture.

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:
•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. 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.
•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.
+ 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.
•Air and material flow adjustments can be made at
the gun on all units. TX 125 units have a material
flow control knob (G).
+ 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.
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.
To Get Less Material
Try one or a combination of these methods:
•Open air valve.

Shutdown and Cleanup
Shutdown and Cleanup
Keep pump and hose clean when switching between simulated acoustic, knockdown and orange peel
applications. A dirty pump can release particles of texture into the finish.
CAUTION
•To increase pump life, turn power off when not spraying.
•Before removing material hose be sure pressure is relieved and material is not in hose.
•To keep unit in good operating condition, always clean it thoroughly and prepare it properly for storage.
6. Fill material hopper with 2-4 gallons of clean water.
7. Spray inside material hopper to circulate water
through gun and hose. While circulating water, use
gun to clean material hopper.
