Why doesn't my Graco HVLP Paint Sprayer shut off in AutoStart mode?
- J
  Jeremy RogersSep 2, 2025
  If your Graco Paint Sprayer does not automatically shut off while in AutoStart setting (ProContractor and ProComp models only), it could be due to leaking air hose connections. Verify that the air hose and attached components are those shipped with the sprayer. Disconnect the air hoses and check that the o-ring is present inside the connection fitting at the turbine end of the hose. If you're using a whip hose, verify the gasket is present inside the connection fitting, and securely connect all hose connections. If necessary, replace with manufacturer-approved HVLP accessories. Another possible cause is a gun leaking air; verify you are using an Edge II Plus gun. If AutoStart functions when the air valve at the end of the hose is closed, the gun may need cleaning.

How to fix a poor spray pattern on my Graco Paint Sprayer?
- I
  ipetersonSep 22, 2025
  A poor spray pattern can be caused by plugged air cap horn holes and/or a plugged fluid nozzle. Soak the air cap and/or fluid nozzle in solvent. Clean the air cap horn holes with a non-metallic item to avoid permanently damaging them.

What causes fish eyes when using Graco HVLP Paint Sprayer?
- A
  aalexanderSep 18, 2025
  Fish eyes, which are small pools on the painted surface that won't fill, are caused by silicone contamination from lubricants, grease, polish, or waxes on the surface being sprayed. Clean all parts with a cleaning solvent, using a solvent rag and a clean rag to wipe with, replacing rags as needed. If the problem continues, use a fish eye eliminator.

Why is my clear coating milky after using Graco HVLP?
- N
  Nathan StevensSep 16, 2025
  Clear coatings appear milky, or 'blushing,' because moisture condensation gets trapped in the lacquer when spraying in hot, humid conditions. To prevent this, allow the turbine to warm up for a few minutes before spraying. Store the lacquer off concrete floors at room temperature. Apply lighter coats, allow for proper drying time, and use a slower evaporating solvent or retarder. Avoid spraying in windy conditions.

How to fix solvent pops or bubbles when using Graco HVLP Paint Sprayer?
- J
  Jeremiah CrawfordSep 14, 2025
  Solvent pops or bubbles occur when the sprayed surface dries before the solvent gas can be released. To resolve this, apply fluid in lighter coats to allow for proper evaporation and use the recommended thinners. You can also follow the solutions for an orange peel finish.

What to do if my Graco HVLP has runs and sags?
- W
  wyoungSep 12, 2025
  Runs and sags happen when you apply too much paint per pass for the drying conditions. To fix this, move the gun faster, decrease the fluid flow, and maintain the correct spraying distance. Also, reduce the amount of thinner or use a faster-drying thinner.

Why does my Graco Paint Sprayer have an orange peel finish?
- D
  Dr. James MooreSep 10, 2025
  An orange peel finish, where the paint surface isn't smooth, can occur for several reasons. The paint droplets might be too large, so maintain the proper spraying distance and keep the turbine air filters clean to ensure full airflow. Avoid using an air hose that's too long. If the droplets are still too large, reduce the fluid. Another cause can be that paint droplets are drying too fast; avoid direct sunlight and use a slower evaporating solvent or a retarder in warmer temperatures. Also, cold weather spraying can cause this, so keep the fluid and object as close to room temperature as possible, as paint thickens on cold surfaces.

What causes a pulsing spray pattern in my Graco HVLP Paint Sprayer?
- B
  barrmichaelSep 7, 2025
  A pulsing spray pattern in your Graco Paint Sprayer can occur if air is not fully evacuated from the FlexLiner System.

Why is there fluid at the bottom of the cup of my Graco HVLP?
- C
  Christine MartinezSep 6, 2025
  If you see fluid present at the bottom of the cup of your Graco Paint Sprayer, it could be because the FlexLiner is not installed; install the FlexLiner. Another possibility is that the FlexLiner is damaged; replace the FlexLiner.

Why is my Graco Paint Sprayer not starting?
- J
  jenniferspencerAug 21, 2025
  If your Graco Paint Sprayer isn't starting, there are several potential causes related to power. First, ensure the electrical outlet has power and cycle the ON/OFF switch. Check that the correct power cord is properly plugged in. Also, examine the circuit breaker and push to reset it if necessary. If the issue persists and you have a ProContractor or ProComp model in AutoStart, confirm the air valve before the gun is open and trigger the gun.
