HVLP Spray Equipment/Finish Troubleshooting
18
Note: For fast-drying automotive materials and some lacquers, prepare material to be
sprayed according to manufacturer’s recommendation. The hot air produced by the
turbine quickly dries the solvents required to thin these materials. We recommend
that you thin these materials 5% to 10% more than the recommended instructions
of the manufacturer, or use a retarder.
Filter warning light on. Air filters clogged. Clean or replace filters.
No trigger pull. Material adjustment knob too tight. Turn counter-clockwise.
Unit has no power. Blown fuse. Check and replace fuse.
Cup doesn't retain power. Worn cup gasket. Replace.
Cup ears bent. Straighten (do not over-tighten).
Excessive arcing/sparking. Worn turbine brushes. Replace brushes.
Damaged commutator. Replace turbine.
Finish Troubleshooting:
Orange peel. Paint drying too fast. Use slower solvent or retarder.
Gun too far from surface. Move closer.
Material too heavy. Reduce viscosity. Try Paint Mate
as an additive for latex.
Dry spray with lacquer. Solvent flash too fast. Add retarder to slow flash time.
Runs and sags. Material too thin. Add unthinned material.
Moving gun too slow. Speed up passes.
Too much material. Reduce material flow by adjusting
material adjustment knob.
Pinholing and solvent pops. Trapped solvents. Apply material in lighter coats allowing
solvents time to evaporate.
Pigment settling. Possible bad product. Replace.
System contamination. Thoroughly clean all parts.
Fish eyes. Possible silicone contamination. Use solvent to clean all parts.
Blistering. Moisture in/on spray surface. Dry surface completely.
Incompatible topcoats or undercoats. Ensure coatings’ compatibility.
Lumpy, coarse surface. Dirt on spray surface. Thoroughly clean surface.
Mottled surface finish. Too much thinner. Reduce thinner.
Poor spray technique. Always square gun with spray surface.
