Application
Methods
Hold
the gun perpendicular to the surface. Keep the
gun at an even 12 to 14 in. (300 to 356 mm) from the
surface you are spraying. See Fig. 7.
Begin moving the gun horizontally at a steady rate.
Start the spray stroke of
f the target surface and pull
the trigger as the gun is moving. Then, while the gun is
still moving, and as you approach the other edge of the
surface, release the trigger
. This method avoids ex
-
cess paint buildup at the end of each stroke.

Move the gun at a speed that provides a full, wet
coating to be applied without runs or sags. Lap each
stroke 50% over the previous stroke to produce a
uniform paint thickness. Spray in a uniform pattern
from right to left and then left to right for a professional
finish. See Fig. 8.

The
best way to control the rate of coverage is with the
gun tip size.
A small tip orifice applies less paint. A
larger tip orifice applies more paint. The width of the
pattern depends on the fan pattern of the tip you
choose.
Do not try to increase coverage by increasing the fluid
pressure! Use the lowest pressure needed for good
results. This prolongs the life of your sprayer and
reduces paint lost by overspray
.
For interior corners aim the gun toward the center of
the corner to be sprayed. By dividing the spray pattern
this way
, the edges on both sides are sprayed evenly
.

If there is a wind, angle the spray pattern into the wind
to minimize drifting. Paint from the ground to the roof.
Shrubs. T
ie back shrubs with rope and stakes. Cover
them with a dropcloth as the painter approaches the
area. Remove the dropcloth as soon as the area is
painted to prevent damage.
Concrete walks.
If the walkways will be walked on,
cover them with a canvas dropcloth to avoid slipping.
Otherwise a plastic cloth can be used.
Electrical outlets and lamps. Protect electrical outlets
with masking tape. Cover lamps with plastic bags
secured with masking tape.
Nearby objects.
Move portable objects upwind of the
surface to be sprayed. If there is a nearby home, make
a protective barrier by hanging plastic drop cloths
between two long poles.
