Spraying

NOTE: When spraying block filler, mastics or high solid
coating, remove the gun filter and high pressure
filter screens.

Spraying technique

The key to a good paint job is an even coating over the entire
surface. This is done by using even strokes. Keep your arm
moving at a constant speed and keep the spray gun at a constant
distance from the surface. The best spraying distance is 10 to 12
inches between the spray tip and the surface.
Even coat throughout
Keep stroke smooth and at an even speed.
Keep the spray gun at right angles to the surface. This means
moving your entire arm back and forth rather than just flexing
your wrist.
Light Coat
Do not flex wrist while spraying.
Keep the spray gun perpendicular to the surface, otherwise one
end of the pattern will be thicker than the other.
Approximately
10 to 12 inches
Right way
Wrong way
The spray gun should be triggered by turning it on and off with
each stroke. This will save paint and avoid paint buildup at
the end of the stroke. Do not trigger the gun during the middle
of a stroke. This will result in an uneven spray and splotchy
coverage.
