SPRAY TECHNIQUE - Continued
It is important to "trigger" the gun after gun move ment
(arm movement) has started and release trig ger (shut
gun off) before gun movement ends. Gun move ment
is always longer than actual paint (spray) stroke. In
that manner, even blend ing and uniform paint coat
thickness is achieved over the entire sur face. When
the gun is in mo tion as the trigger is pulled, it de pos its
an even amount of paint.
Overlap the previous pass by half the width of the
spray pattern. Aim at the bottom of the pre vi ous
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 si ble.
FOR EVEN PAINT COAT OVERLAP HALF
THE WIDTH OF EACH PAINT STROKE.
Adjust pressure control knob so that paint is com plete ly
at om ized from the spray gun. In suf fi cient pressure will
result in "tail ing".

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 cor ner. 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 oth er
surface.
