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.
Slowly add one 40 lb. (18 kg) bag of texture material to 5-6 gallons
(18.9-22.7 liters) of clean water as instructed on the bag instructions.
Mixing Material
ti2496
2.
Agitate to mix, using a half-inch, variable speed drill with mixing paddle, to a smooth, lump-free consistency.
3.
Allow ceiling texture to set for at least 15 minutes.
Then remix prior to use.
ti2497a
4.
After texture material is thoroughly mixed, gently set ball end of Material Thickness Gauge on surface of mixture.
For an accurate test, be sure gauge is completely dry and clean every time it is used.
5.
Observe the ball on the material. When the material is thin enough to spray the ball will sink completely into the mixture.
6.
If the ball does not sink completely into the mixture within 10 seconds, add more water, agitate and try test again.

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.
+ 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 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.
10 309863C
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
• Turn off sprayer if you are going to stop spraying for 5 minutes or longer.
• 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.
