Spraying
Adjust Spray Pattern
NEVER trigger the gun while adjusting the ears on
the air cap. NEVER point the spray gun at any part
of the body.
Material Flow Adjustment
Set the material volume by turning the regulator on the
trigger of the spray gun.
Nut
Air cap
Round pattern
Horizontal pattern
Vertical pattern
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
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 - outdoor use only
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.
• The closer your sprayer is to the object being sprayed the
lower the overspray.
• 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.

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.
