PROPER SPRAYING TECHNIQUE
STOP
The room you are spraying must be properly
masked off in order to prevent overspray from
covering anything you do not want sprayed.
Make sure you have properly masked the room.
i
If spraying with a paint sprayer 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 and/or
test with water.
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) to eight (8) inches from the
spray surface, depending upon the spray pattern size desired. With reduced
material flow, you can get closer on the spraying surface.
•
Spray parallel to the surface with smooth passes at a consistent speed as
illustrated (A). Doing this will help avoid irregularities in the finish (i. e. runs
and sags).
•
Always apply a thin wet coat of material on the first pass and allow to dry before
applying a second, slightly heavier coat.
•
When spraying, overlap each spray pass by at least 50% This will ensure full
coverage.
•
When spraying, trigger the gun before the spray object and release the trigger
after you are past the spray object.
STOP
During a project, periodically wipe the nozzle tip with a cloth to remove any dried paint.
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.
