It is important to "trigger" the gun after gun
movement (arm movement) has started and re-
lease trigger (shut gun off) before gun movement
ends. Gun movement is always longer than actual
paint (spray) stroke. In that manner, even blending
and uniform paint coat thickness is achieved over
the entire surface. When the gun is in motion as
the trigger is pulled, it deposits an even amount of
paint.
Overlap the previous pass by half the width of
the spray pattern. Aim at the bottom of the pre-
vious pass.
Spray with uniform strokes from left to right
and from right to left, holding stroke speed, dis-
tance, lapping, and triggering as uniform as pos-
sible.
FOR EVEN PAINT COAT OVERLAP HALF
THE WIDTH OF EACH PAINT STROKE.

The Actual Paint Stroke
Adjust pressure control knob so that paint
is completely atomized from the spray gun.
Insufcient pressure will result in "tailing".
TAILING GOOD PATTERN FOG, OVERSPRAY
Too much pressure will result in excess fog and
overspray, excessive tip wear, and increased
sprayer wear and tear.
"Inside" and "outside" corners can be sprayed.
Aim the spray gun toward the center of the corner.
The spray pattern is divided in half, and the edges
of the spray pattern on both walls are the same.
Always use the lowest pressure possible to obtain
desirable results.
Test the spray pattern on a piece of cardboard or
other surface.
