Proper Spraying Technique

STOP

The room you are spraying must be properly

masked in order to prevent overspray from

covering woodwork, oors or furnishings. Make

sure you have properly masked the room per the

instructions on the enclosed “Taping Guide”.

If spraying with an air-assisted 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

STOP

It is important to keep your arm moving

whenever the gun is being triggered. If you

pause or linger in one spot too long, too much

material will be sprayed to the surface.

• Position the spray gun perpendicular to and six (6) 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 nish (i. e. runs and sags).

• Always apply a thin coat of material on the rst pass and

allow to dry before applying a second, slightly heavier coat.

6 -12 inches

Correct

Even coat throughout

Keep stroke smooth and at an even speed

• When spraying larger surfaces, overlap each spray pass by

at least 50% This will ensure full coverage.

• 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

nish possible.

Incorrect

Do not ex wrist while spraying.

Light coat Heavy coat Light coat

When you quit spraying for any length of time, turn the

turbine OFF and place the spray gun into the spray gun

holder on the turbine.

Pattern Examples

Use the images and guidelines below in order to assist you

in achieving the desired spray pattern for your project.

These are meant to be general starting points - you may

have to slightly modify certain controls on the system in

order to get the exact performance you need.

Low volume and pressure - round pattern

Generally, low volume and pressure is needed for spraying

smaller surface areas, such as corners, lattice, or spindles.

• If you feel the material is going on too thin, increase

the material volume.

• If you feel the material is going on too thick, decrease

the material volume even further or move the spray

gun further away from the surface.

High volume and pressure - vertical/horizontal

pattern

Generally, high volume and pressure is needed for spraying

large surface areas, such as a wall.

• The spray nozzle will determine the movement

direction of the spray gun.

• With the yellow spray gun, the pattern can be made

narrower by moving closer to the spray surface, and

wider by moving farther away.

Note: If after following the guidelines on these two pages

you are still not getting the spray performance you need,

refer to the ‘Troubleshooting’ section on page 11.

Besides adjusting the controls, other factors that should be

considered when spraying:

• Distance from the spray object - if you are too far

from the spraying surface, the material will go on too

thin, and vice versa.

• Material thickness - if the spray pattern runs and/or is

too splotchy, the material may need to be thinned.

• Spray gun movement - moving the gun too quickly

will cause the spray pattern to be too thin and excess

overspray. Moving the gun too slowly will cause the

spray pattern to be too coarse or thick.
