The spray pattern shape is adjusted by turning the
ears of the air cap to either the vertical, horizontal, or
diagonal positions. The positions of the air cap and
the corresponding spray pattern shapes are illustrated
below.
Test each pattern and use whichever pattern is suitable
for your application.

Proper Spraying Technique
If spraying with an HVLP spray system is new or
unfamiliar to you, it is advisable to practice on a piece
of scrap wood or cardboard before beginning on your
intended workpiece.
Surface Preparation
All objects to be sprayed should be thoroughly cleaned
before spraying material on them. Areas not to be
sprayed may, in certain cases, need to be masked or
covered.
Spray Area Preparation
The spray area must be clean and free of dust in order
to avoid blowing dust onto your freshly sprayed surface.
How to Spray Properly
• Position the spray gun perpendicular to and one (1)
or more inches from the spray surface, depending
upon the spray pattern size desired.
• Spray parallel to the surface with smooth passes at a
consistent speed as illustrated below. Doing this will
help avoid irregularities in the finish (i. e. runs and
sags).
• Always apply a thin coat of material on the first pass
and allow to dry before applying a second, slightly
heavier coat.
1 to 12 inches
Correct
Even coat throughout
Keep stroke smooth and at an even speed
• When spraying, always trigger the spray gun
after spray pass has begun and release trigger
before stopping the pass. Always keep the gun
pointed squarely at the spray surface and overlap
passes slightly to obtain the most consistent and
professional finish possible.
Incorrect
Do not flex wrist while spraying.
