SPRAYING
You are now ready to use the ENFORCER™
NOTE: There are several adjustments that can be made to the
ENFORCER™ and the compressor to get the texture of spray you
desire.
• The more open the trigger; the more material will be
applied with a resulting coarser pattern.
• The higher the air pressure, the finer the pattern; the lower
the air pressure, the coarser the pattern.
• The higher the air flow, the finer the pattern; the lower the
air flow, the coarser the pattern.
• Larger orifice openings will produce a coarser pattern
than will a smaller opening.
• Of the three most popular patterns – orange peel,
knockdown, and popcorn – orange peel and knockdown
are generally applied to walls while popcorn aggregate is a
ceiling finish.
• The more open the mud flow control on the ENFORCER™,
the more mud that will be applied.
To apply orange peel: Select the second smallest opening (#6) in
the orifice plate, set the trigger so that the end of the air nozzle is
approximately 1/8" (3.18 mm) from the orifice plate. Air pressure
should be 22–30 psi. Again, before spraying the finished product,
check for the desired texture on a scrap piece of sheetrock.
To apply knockdown: Also referred to as splatter, change the orifice
plate to the middle opening (.315"/8.0 mm dia.) (#4), set the trigger
fully open. The air pressure should be reduced to 18–25 psi. Again,
before spraying finished product, check for the desired texture on a
scrap piece of sheetrock.
To apply popcorn ceiling texture: Use one of the largest open-
ings (#1, 2, or 3) - Which one will depend on the size of the acoustic
aggregate. The trigger setting should be fully open. The air pressure
should be 30–40 psi.
NOTE: The textures described above are made using either a 3/8" or
1/2" I.D. hose. If you are using a 1/4" I.D. hose, use greater air pressures
than specified.
