SPRAYING
SPRAYING TECHNIQUE
1. The key to a good paint job is an even coating over the entire surface. With spray painting, this is
done by using even strokes, with your arm moving at a constant speed and keeping the spray gun a
constant distance from the surface.
2. As much as possible, 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.

3. Keep the spray gun perpendicular to the surface, otherwise one end of the pattern will be thicker
than the other.

4. In most cases, the best spraying distance is 10 to 12 inches (25-30cm) between the spray tip and
the surface.
5. The spray gun should be triggered off at the end of each stroke and on again at the beginning of the
next. This avoids paint buildup at the end of the stroke which may result in runs and sags. Triggering
at the end of the stroke also saves paint and results in a better looking job. (See picture below)

the gun will allow a full, wet coating to be
applied without runs or sags.
Lapping
each stroke about 40% over the
previous
stroke
produces
uniform paint thickness. Spraying in a uniform
pattern alternately from right to left and then left to right, provides a
professional finish. (See picture on the right)
One way to do this is to point the spray tip at the edge of the last stroke
