TROUBLESHOOTING FINISH PROBLEMS
Problem
Probable Cause
Solution(s)
Runs or Sags
A. Coating has been over-
diluted
B. Application speed too slow
C. Improper overlapping
D. Needle and Fluid Tip too
large
E. Film thickness is too thick for
one coat
F. Gun too close to surface
G. Too much atomizing air
A. Add undiluted material and
mix thoroughly; flush gun
with new mixture
B. Increase application speed
C. Overlap passes by 50%
D. Measure material viscosity;
select Atomizing Kit
accordingly
E. Consider spraying too thinner
coats
F. Hold gun +/- 6” from the
surface when spraying
G. Reduce turbine air volume
output using VSC
“Orange Peel”:
Finish has the texture of an
orange peel. A dimpled
appearance, often very glossy.
A. Material needs to be diluted
B. Incorrect thinning solvent:
evaporating too fast
C. Gun too close to surface
D. Film thickness is too thick
E. Incorrect amount of
atomizing air
F. Ambient air temperature too
high: material drying before
has chance to flow-out
A. Measure viscosity; follow
manufacturers instructions
for dilution; add thinning
solvent
B. Use slower thinning solvent
or retarder
C. Hold gun +/- 6” from surface
when spraying
D. Apply a thinner coat
E. Adjust turbine air volume
output using VSC
F. Reduce air temperature in
spray area and/or add
retarder or flow agent to
material
“Fish Eyes”:
Small round depressions in the
paint film. Normally form as soon
as part is sprayed.
A. Contaminant on the surface
(oil, moisture) preventing the
coating from adhering to the
surface in certain spots
A. Very difficult to correct once
surface is sprayed. Ensure
that surface is clean, dry and
free from any contaminants
prior to spraying
“Dry Spray”:
Surface is dull and rough. Dry
paint particles protruding from, or
sitting on surface. Unlike Orange
Peel, Dry Spray is always low in
gloss. Feels like sand paper.
A. Gun too far from surface
B. Incorrect amount of
atomizing air
C. Incorrect thinning solvent:
evaporating too fast
D. Film thickness is too thin
E. Application speed too fast
A. Hold gun +/- 6” from surface
when spraying
B. Adjust turbine air volume
output using VSC
C. Use slower thinning solvent
or retarder
D. Apply a “wetter” coat
E. Slow down speed of motion
“Blushing”:
Large whitish areas in the finish
A. High humidity in the spray
area: moisture has
condensed in the coating as
it was being sprayed.
B. Incorrect thinning solvent:
evaporating too fast
A. Reduce humidity in spray
area and/or add retarder to
coating being sprayed
B. Use slower thinning solvent
or retarder
