Mix the Material
Always wet out the pump, hose, and applicator before
loading the material. See Wet Out the System, page
13.
Always follow the material manufacturer's instructions
for the material being sprayed. Mortar must be
thoroughly mixed to a smooth consistency before
loading it in the hopper.
•
Always add the powder slowly to the fluid while
mixing. Do not add fluid to the powder.
•
In non-explosive atmospheres only: Use a powerful
mixer drive such as a minimum 800 W, 1/2 in. drive,
electric drill. Gear reduced drills work best. Drill
should have high torque at 300-1200 rpm.
•
A heavy-duty drywall mud "H" blade or large "Jiffy"
blade generally works well for mixing.
NOTE: It will take most of the first batch of material to fill
the pump and hoses.
Managing Mortar After Mixing
•
Pay close attention to the work life of the material
being used.
•
Only mix the mortar kits as needed. Do not let
mixed mortar sit longer than necessary.
•
Scrape mortar down the sides of the hopper as the
hopper material level lowers. Do not let older mortar
cure on the walls.
•
Occasionally, do not refill the hopper until it is almost
empty. This ensure all material in hopper is used
while fresh.

Prime with Material
To prevent material curing in the system, never load
material into a dry system. Loading material into a dry
system will cause the material to stick to internal com-
ponents and cure, causing damage and requiring
replacement of those parts.
The applicator nozzle or tip must be removed during
priming. Always push out any remaining "wet out" fluid
into a waste container before circulating mortar. Always
circulate clean mortar back into the hopper for a few
minutes before beginning to spray.
1. Wet out the system. See Wet Out the System,
page 13.
2. Mix the material. See Mix the Material, page 15.
3. Close the bleed type master air valve (B).

4. Remove tip from applicator.
5. Fill the clean hopper with at least 5 gallons of the
material to be sprayed. If using 60 ft of material
hose, then fill with 6 gallons.
