Troubleshooting
Spray Finish Problems
PROBLEM CAUSE SOLUTION
Orange peel finish — Paint
surface not smooth
Paint droplets too large D Maintain proper spraying distance.
See page 12.
D Keep the turbine air filters clean to
allow full air flow.
D Do not use an air hose that is too
long to provide sufficient
atomization pressure.
D If droplets are still too large, reduce
the fluid.
Paint droplets drying too fast to
properly flow out of gun
Keep the object being sprayed out of
direct sunlight. When spraying in
warmer temperatures, use a slower
evaporating solvent or a retarder.
Cold weather spraying Keep the fluid and the object being
sprayed as close to room temperature
as possible. When sprayed on a cold
surface, most paints will become too
thick to flow properly.
Blushing — Clear coatings
appear milky
Moisture condensation is trapped in
the lacquer when spraying in hot,
humid conditions
D Allow the turbine to warm up a few
minutes before spraying.
D Store the lacquer off concrete
floors, at room temperature.
D Apply lighter coats and allow for
proper drying time.
D Use a slower evaporating solvent
or retarder.
D Do not spray in windy conditions.
Fish eyes — Small pools on
painted surface that will not
fill
Silicone contamination from lubricants,
grease, polish, or waxes on the
surface being sprayed
Clean all parts with a cleaning solvent;
use a solvent rag and a clean rag to
wipe with. Replace rags as needed. If
the problem persists, use a fish eye
eliminator.
Runs and sags Applying too much paint per pass for
the drying conditions
D Move the gun faster or decrease
the fluid flow.
D Maintain proper spraying distance.
See page 12.
D Reduce the amount of thinner or
use a faster drying thinner.
Solvent pops or bubbles Sprayed surface drying before solvent
gas can be released
D Apply fluid in lighter coats to allow
for proper evaporation.
D Use the recommended thinners.
D Follow the solutions, above, for
Orange peel finish — Paint droplets
too large.
