Thin distribution in center of
pattern “horns”
Worn tip Change to new tip
Wrong tip Use tip with narrow spray angle
Thick skin on work Material too viscous Thin cautiously
Application too heavy Reduce pressure and/or use tip in next
smaller tip size
Coating fails to close and
smooth over
Material too viscous Thin cautiously
Spray pattern irregular,
deflected
Orifice clogged Clean carefully
Tip damaged Replace with new tip
Craters or pock marks, bub-
bles on work
Solvent balance Use 1 to 3% “short solvents remainder “long”
solvents (this is most likely to happen with
material of low viscosity, lacquers, etc.)
Clogged screens Extraneous material in paint Clean screen
Course pigments Use coarse screen if orifice size allows.
Poorly milled pigments (paint
pigments glocculate)
Use courser screen, larger orifice tips. Obtain
ball milled paint. If thinner had been added,
test to see if a cover screen. Incompatible
drop placed on top of paint mixes or flattens
out on the paint mixture and thinners on the
surface. If not, try different thinner in fresh
batch of paint.
Excess paint builds on tip
guard
Spray gun too close to surface Hold gun further from surface sprayed
Pressure setting too high Reduce pressure setting
Drips, spits from tip Valve seat and/or ball in gun
head damaged or worn
Service spray gun, replace valve assembly
Tip clogs continually Debris in paint Thoroughly strain the paint before use
Gun filter missing Do not operate without inlet strainer
Coarse filter mesh Do not operate without inlet strainer
