Spray Pattern Troubleshooting
NOTE: Some spray pattern problems are caused by the improper balance between air and fluid.
Problem
Cause
Solution
Air flow too high.
Use gun atomizing air adjustment
valve to reduce air flow.
Spray tip worn.
Replace tip.
Diffuser worn.
Replace diffuser.
Spray is too forceful (high velocity).
Fluid flow too high.
Use smaller tip or lower pressure
Air flow too low.
Use gun atomizing air adjustment
valve to increase air flow.
Spray gun spitting.
Tip size is too large.
Use smaller tip.
Paint not properly filtered.
Clean or replace the gun filter.
Install inline filter or clean/replace
inline filter.
Tip clogging.
Tip size is too small.
Use larger tip.
Tip is clogged.
See “Tip clogging,” above.
Distorted spray pattern (heavy to
one side).
Spray tip worn or damaged.
Replace tip.
