Problem
Cause
Solution
Orange peel finish - Paint 
surface not smooth
Pain droplets too large
Maintain proper spraying distance, page 2.
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.
If droplets are still too large, reduce fluid.
Paint droplets drying too fast to prop-
erly flow out of gun
Keep object being sprayed out of direct sunlight. 
When spraying in warmer temperatures, use a 
slower evaporating solvent or a reducer.
Cold weather spraying
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.
Blushing - clear coatings 
appear milky
Moisture condensation is trapped in 
lacquer when spraying in hot, humid 
conditions
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 dry-
ing time.
Use a slower evaporating solvent or 
reducer.
Do not spray in windy conditions.
Fish eyes - small pools on 
painted surface that will not 
fill
Silicone contamination from lubri-
cants, grease, polish, or waxes on 
the surface being sprayed
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 elimi-
nator.
Runs and sags
Applying too much paint per pass for 
the drying conditions
Move gun faster or decrease fluid flow.
Maintain proper spraying distance, page 2.
Reduce amount of thinner or use a faster 
drying thinner.
Solvent pops or bubbles
Sprayed surface drying before sol-
vent gas can be released
Apply fluid in lighter coats to allow for proper 
evaporation.
Use the recommended thinners.

Paint Droplets Too Large in this Trouble-
shooting Table.
