How to Adjust Airless Paint Sprayer

Painting can be a relatively simple task with the right tools and knowledge. Airless paint sprayers provide a quick and efficient way to cover large surfaces with paint. However, to achieve the best possible results, it’s important to ensure that the paint sprayer is properly adjusted. This article will discuss the steps to adjust an airless paint sprayer for optimum performance.

Setting the Correct Spraying Pressure

One of the most crucial aspects of adjusting an airless paint sprayer is setting the correct spraying pressure. This ensures that the paint is atomized properly and applied evenly. Here are the steps to set the correct spraying pressure:

  1. Start by cleaning the pump, gun, and hose to ensure no blockage could affect the pressure.
  2. Empty the system of any remaining paint and prime it with the new paint to be used.
  3. Once the system is primed, adjust the pressure settings on the paint sprayer. The optimal pressure will depend on the type of paint being used and the surface being painted. Consult the paint manufacturer’s guidelines for the recommended pressure settings.
  4. After adjusting the pressure, test the spray pattern on a piece of cardboard. The pressure may need further adjustment if the pattern has tails or appears uneven.

Reasons for High Pressure

Understanding the reasons for high pressure in an airless paint sprayer can help troubleshoot and make necessary adjustments. Here are some common reasons for high pressure:

  • Pump leaks
  • Obstructions in the spray tip
  • Issues with the gun and hose

Spraying with Different Tips

It’s essential to adjust the pressure settings when using different spray tips. Tips with varying sizes and angles may require adjustments to the spraying pressure to achieve the desired results.

Getting the Perfect Spray Pattern

Obtaining the perfect spray pattern is essential for a professional-looking finish. Adjusting the pressure and ensuring the spray gun is held correctly from the surface can help achieve the perfect spray pattern.

Feathered Edges and Straining Paints

When using an airless paint sprayer, attention to detail, such as feathered edges and straining paints, can significantly improve the finish. Feathered edges prevent visible overlapping lines while straining paints removes any impurities that could affect the spray pattern.
