Spraying
WARNING: POSSIBLE INJECTION HAZARD. Do not
spray without the tip guard in place. Never trigger the
gun unless the tip is in either the spray or the unclog
position. Always engage the gun trigger lock before
removing, replacing, or cleaning tip.
Spraying Technique
The following techniques, if followed, will assure professional
painting results.
Hold the gun perpendicular to the surface and always at
equal distance from the surface. Depending on the type of
material, surface, or desired spray pattern, the gun should be
held at a distance of 12 to 14 inches (30 to 35 cm).
Move the gun either across or up and down the surface at a
steady rate. Moving the gun at a consistent speed conserves
material and provides even coverage. The correct spraying
speed allows a full, wet coat of paint to be applied without runs
or sags.
Holding the gun closer to the surface deposits more paint on
the surface and produces a narrower spray pattern. Holding
the gun farther from the surface produces a thinner coat and
wider spray pattern. If runs, sags, or excessive paint occur,
change to a spray tip with a smaller orifice. If there is an
insufficient amount of paint on the surface or you desire to
spray faster, a larger orifice tip should be selected.
Maintain uniform spray stroke action. Spray alternately from
left to right and right to left. Begin movement of the gun
before the trigger is pulled.
Avoid arcing or holding the gun at an angle. This will result in
an uneven finish.
Proper lapping (overlap of spray pattern) is essential to an
even finish. Lap each stroke. If you are spraying
horizontally, aim at the bottom edge of the preceding stroke,
so as to lap the previous pattern by 50%.

For corners and edges,
split the center of the
spray pattern on the
corner or edge and spray
vertically so that both
adjoining sections receive
approximately even
amounts of paint.
If conditions are windy, angle
the spray pattern into the wind
to minimize drifting. Work from
ground to roof. Do not attempt
to spray if wind is excessive.
When spraying with a shield,
hold it firmly against the surface. Angle the spray gun slightly
away from the shield and toward the surface. This will prevent
paint from being forced underneath.
Shrubs next to houses should be tied back and covered with
a canvas cloth. The cloth should be removed as soon as
possible. Titan gun extensions are extremely helpful in these
situations.
Nearby objects such as automobiles, outdoor furniture, etc.
should be moved or covered whenever in the vicinity of a
spray job. Be careful of any other surrounding objects that
could be damaged by overspray.
Practice
1. Be sure that the paint hose is free of kinks and clear of
objects with sharp cutting edges.
2. Turn the pressure control knob counterclockwise to its to
its lowest setting.
3. Turn the PRIME/SPRAY valve up to its SPRAY position.
4. Turn the pressure control knob clockwise to its highest
setting. The paint hose should stiffen as paint begins to
flow through it.
5. Unlock the gun trigger lock.
6. Trigger the spray gun to bleed air out of the hose.
7. When paint reaches the spray tip, spray a test area to
check the spray pattern.
8. Use the lowest pressure
setting necessary to get a
good spray pattern. If the
pressure is set too high, the
spray pattern will be too light.
If the pressure is set too low,
tailing will appear or the paint
will spatter out in gobs rather
than in a fine spray.
