Mixing Material
Dry Mix - 40 lb (18 kg) bag
1. Carefully mix texture material and water according
to manufacturer instructions on bag.
2. Agitate to mix, using a half-inch, variable speed drill
with mixing paddle, to a smooth, lump-free consis-
tency.
3. Allow ceiling texture to set for at least 15 minutes.
Then remix prior to use.
4. After texture material is thoroughly mixed, gently set
ball end of Material Thickness Gauge on surface of
mixture.
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.
Premix
1. Slowly add approximately 2 to 4 qts (1.9 to 3.8 liters)
of water to a 5 gallon (18.9 liter) bucket of premix.
2. Agitate to mix, using a half-inch, variable speed drill
with a mixing paddle, to a smooth, lump-free consis-
tency.
3. After texture material is thoroughly mixed, gently set
ball end of Material Thickness Gauge on surface of
mixture.
4. Observe the ball in material. When the material is
thin enough to spray the ball will sink completely into
the mixture.
5. If the ball does not sink completely into the mixture
within 10 seconds, add more water, agitate and try
test again.
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 mix-
ture is thin enough to spray.
*The Material Thickness Gauge will only deter-
mine 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 thin-
ner.
For best results, do not use partial bags of material.
For an accurate test, be sure gauge is completely
dry and clean every time it is used.
