Spray Techniques
Use a piece of scrap cardboard to practice
these basic spraying techniques before you
begin spraying the surface.
• Hold gun 12 in. (30 cm) from surface
and aim straight at surface. Tilting gun
to direct spray angle causes an uneven
finish.
• Flex wrist to keep gun pointed straight.
Fanning gun to direct spray at angle
causes uneven finish.
Triggering Gun
Pull trigger after starting stroke. Release
trigger before end of stroke. Gun must be
moving when trigger is pulled and released.
Aiming Gun
Aim center of spray of gun at bottom edge of
previous stroke, overlapping each stroke by
half.
Spray Pattern Quality
A good spray pattern is evenly distributed as
it hits the surface.
• Spray should be atomized (evenly dis-
tributed, no gaps at edges).
If tails persist when spraying at the highest
spray pressure:
• Spray tip may be worn. See Spray Tip
Selection, page 30.
• A smaller spray tip may be needed.
• Material may need to be thinned. If
material needs to be thinned follow
manufacturer’s recommendations.
