Spray Finishing Application

1. Maintain a distance of approximately 8 to 12 in. (200
to 300 mm) from the object being sprayed.
2. Hold the gun perpendicular to the surface.
3. Engage the trigger (9).
4. Spray smooth, even, and parallel strokes. Overlap
each stroke by 50% for even coverage. Do not arc
the strokes. Arcing causes uneven coverage. See
F . 24.

HVLP Verification
21g
Many air quality authorities accept air assist spraying as
an efficient process and in compliance with
environmental regulation.
To comply with HVLP requirements, the air pressure at
the air cap must be less than 10 psi (.7 bar, 07 MPa).
Use an HVLP Verification Kit to verify the air cap air
pressure. See the Air Cap Selection Guide, page 54.
HVLP Verification Kits are for testing only. Do not use
for actual spray application.
