Original Instructions. This manual contains English. MM 3A3482. Revision A, April 2016
Correct material mixture is essential for a successful project.
Drywall Compound
Mix the material with water in a separate container before pouring it into hopper.
Dry Mix: Carefully mix material and water according to manufacturer instructions.
Premix: Follow manufacturers recommendations for mixing.
Use Material Thickness Gauge to determine if mixture is thin enough to spray. Be sure gauge
is completely dry and clean every time it is used.
The Material Thickness Gauge will only determine if the material is thin enough to pass through
the pump. For higher speed spraying, your mixture may need to be thinner.
Agitate to mix, to a smooth, lump-free consistency.
Check and thin material periodically. Material may thicken as it sits. Agitate periodically.
After material is thoroughly mixed, gently set ball end of Material Thickness Gauge on surface
of mixture. Best results are obtained when ball sinks completely into the mixture in 6 to 10
seconds. Add more water if the ball does not sink completely into the mixture within 10 seconds
and try test again.
Other Materials
If mixing is required, mix in a separate container before pouring it into hopper.
Follow material manufacturers recommendations for thinning and mixing.
Thickness gauge is not used with materials containing solids.
Once material is mixed pour material into the sprayer hopper.
Step1: Open gun air valve. Step 2: Turn ON/OFF switch to ON position. Step 3: Close gun air valve.
Step 4: Trigger gun into bucket until most of texture mix is pumped out. Step 5: Fill material hopper
with clean water.
Step 6: Spray inside material hopper to circulate water through gun and hose. While circulating water,
use gun to clean material hopper. Step 7: Partially open gun air valve to use air to achieve better
cleaning. Step 8: Spray water into waste bucket to empty material hopper. Step 9: Turn ON/OFF
switch to OFF position. Step 10: Open gun air valve and perform Pressure Relief Procedure.
Step 11: Loosen bottom fitting on hopper. Step 12: Lift hopper straight up, off the unit. Step 13: Plug
opening on bottom of hopper with your hand. Take hopper to cleaning area for cleaning. Step 14: After
cleaning hopper, position it on sprayer handle first. Step 15: Hand tighten fitting. Step 16: Always clean
nozzles with a soft brush after spraying. Nozzles may require replacement depending on abrasiveness
of texture.
