Yes, in most cases, you should clean your spray gun between coats. The level of cleaning required depends on the type of coating you're using and how long you're waiting between applications.

If you're only pausing briefly, a quick wipe of the nozzle or tip with a solvent-dampened cloth is usually enough. This helps prevent clogs and maintains a consistent spray pattern, especially when working with fast-drying materials like water-based paints or lacquers.

However, if there's a longer gap between coats, it's best to flush a small amount of solvent or spray gun cleaner through the gun. This keeps internal components from drying out and ensures smooth, reliable performance when you resume spraying.

How Do You Clean a Spray Gun Between Coats?

Keeping your spray gun in good working order between coats is simple and quick. Follow these steps:

• Wipe the tip or nozzle with a cloth soaked in the appropriate solvent to remove surface buildup.
• Flush a small amount of cleaner through the gun to keep internal passages clear.
• Seal the gun (for example, with a fluid cap or airtight container) to prevent drying if you're pausing for longer periods.
• For a full clean - such as when changing products or finishing a job - disassemble the spray gun and clean each component thoroughly with solvent or spray gun cleaner.
