Troubleshooting
Problem
Orange peel finish - Paint
surface not smooth
Blushing - clear coatings
appear milky
Fish eyes - small pools on
painted surface that will not
fill
Runs and sags
24
Cause
Paint droplets too large
Paint droplets drying too fast to
properly flow out of gun
Cold weather spraying
Moisture condensation is
trapped in lacquer when spraying
in hot, humid conditions
Silicone contamination from
lubricants, grease, polish, or
waxes on the surface being
sprayed
Applying too much paint per pass
for the drying conditions
Solution
•
Adjust fluid control knob on
gun to reduce fluid.
•
Spray further from work
piece.
•
Keep turbine air filters clean
to allow full air flow.
•
Do not use an air hose that is
too long to provide sufficient
atomization pressure.
Keep object being sprayed out of
direct sunlight. When spraying in
warmer temperatures, use a slower
evaporating solvent or a reducer.
Keep fluid and object being sprayed
as close to room temperature as
possible. When spraying on a cold
surface, most paints will become too
thick to flow properly.
•
Allow turbine to warm up a
few minutes before spraying.
•
Store lacquer off concrete
floors, at room temperature.
•
Apply lighter coats and allow
for proper drying time.
•
Use a slower evaporating
solvent or reducer.
•
Do not spray in windy
conditions.
Clean all parts with a cleaning
solvent; wipe with a solvent rag and a
clean rag. Replace rags as needed. If
problem persists, use a fish eye
eliminator.
•
Move gun faster or decrease
fluid flow.
•
Spray further from work
piece.
•
Reduce amount of thinner or
use a faster drying thinner.
