Airless paint sprayers are compact, mechanical devices used for mixing, pumping, and spraying high-quality paints and coatings. They are a popular choice in the painting industry today, not just for their impressive work efficiency, but also because they deliver a more consistent surface finish compared to manual brushing. As such, airless paint sprayers are essential tools for both professional and DIY painting projects.

To extend the lifespan of your airless paint sprayer, it's crucial to clean it thoroughly after each use. Here's a step-by-step guide on the proper cleaning methods:

1.Relieve the Pressure:

Airless paint sprayers operate under high pressure during use. Before cleaning, you must relieve this pressure to prevent serious injuries from pressurized liquids, such as skin contact or fluid splashing.

2.Disassemble the Sprayer:

Remove the tip guard and spray tip to access the internal components.

3.Soak the Pump:

Take the piston pump out of the paint and place it in the appropriate rinse liquid - water for water-based paints, or mineral spirits for oil-based paints.

4.Flush the System:

Turn on the motor or engine, activate the generator, and open the hydraulic pump valve to circulate the rinse liquid through the paint valve and spray gun.

5.Thoroughly Rinse:

Direct the spray gun towards a waste container and squeeze the trigger to flush the entire system until the liquid runs clear.

6.Expel Remaining Fluid:

Lift the piston pump above the rinse liquid level and run the sprayer for 15-30 seconds to expel any leftover fluid.

7.Clean Filters:

Remove, clean, and reinstall any filters on the spray gun and sprayer.

8.Rinse with Solvent:

If water was used for rinsing, do a final rinse with solvent oil or mineral spirits to leave a protective coating and prevent freezing or corrosion.

9.Wipe Down:

Use a cloth soaked in water or mineral spirits to clean the exterior of the sprayer, hose, and spray gun.
