Fluid Nozzle and Spray Disc Selection
Six spray disks and five nozzles are supplied with the sprayer. These parts can be interchanged to produce a pattern
suitable for each job. Use the chart below to help determine the right combination for your application.
Helpful Hints
•
A spraying distance of 18 to 30 in. (0.5 to 0.8 m) is
recommended for most applications.
•
Keep the gun triggered and moving as much as
possible.
•
Set gun trigger latch to hold trigger open and reduce
operator fatigue on large surface areas.
•
Simulated acoustic material with polystyrene texture
compresses easily so system pressure builds up
more slowly.
•
When spraying elastomerics, maintain a wet edge.
Spray vertical passes followed by horizontal passes.
Then hold the gun further away and “dust” the area
to blend the pattern.
•
To spray ceilings as high as 9 to 12 ft (3 to 4 m)
without using stilts or scaffolding, use more
pressure and open gun Air Needle Valve more to
project material onto ceiling.
•
Check material consistency periodically. The
material may thicken as it sits and slow down
production. Check and thin material as needed to
maintain proper consistency.
•
Relieve pressure fully before closing fluid passage
when spraying aggegrate material. Aggregate
material under pressure has a high risk of causing
packout in the gun.
•
When not spraying for extended periods of time,
perform
