Proper Spraying Technique
STOP
The room you are spraying must be properly
masked in order to prevent overspray from
covering woodwork, floors 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 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.
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
finish possible.
Incorrect
Do not flex 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.
