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

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.

Incorrect

Do not flex wrist while spraying.

Light coat

Heavy coat

Light coat

1 to 12 inches

Correct

Even coat throughout

Keep stroke smooth and at an even speed

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.
