Spray Techniques
Use a piece of scrap cardboard to practice
these basic spraying techniques before you
begin spraying the surface.
• Hold Spray Gun 12 in. (30 cm) from
surface and aim straight at surface.
Tilting the Spray Gun to direct the spray
angle causes an uneven finish.
• Flex wrist to keep Spray Gun pointed
straight. Fanning Spray Gun to direct
spray at angle causes uneven finish.
NOTE: How fast you move the Spray Gun will
affect spray application. If material is uneven,
you are moving too fast. If material drips, you
are moving too slow. See Troubleshooting,
page 28.
Aiming Spray Gun
Aim the Spray Gun at the bottom edge of the
previous stroke, overlapping each stroke by
50%.
Triggering Timing
Pull Trigger after starting stroke. Release
Trigger before end of stroke. Spray Gun must
be moving when Trigger is pulled and
released.
Spray Pattern Quality
A good spray pattern is evenly distributed as
it hits the surface.
• Spray should be atomized (evenly
distributed, no gaps at edges).
If tails persist when spraying at the highest
spray pressure:
• Spray Tip may be worn. See Tip and
Pressure Selection, page 16.
• A smaller Spray Tip may be needed.
• Material may need to be thinned. Follow
manufacturers recommendations.
