Inconsistent spraying pattern is a common problem that can arise when the pump pressure is not properly maintained. Troubleshooting paint spray issues starts with ensuring that the pump pressure is set correctly.

If the pressure is too low, the paint may not atomize properly, leading to an uneven spraying pattern. On the other hand, if the pressure is too high, the paint can spit and create blobs on the surface being painted. To avoid these problems, it is crucial to monitor and adjust the pump pressure as needed.

Now, let’s move on to another factor that can cause airless sprayers to spit: thin paint.

Thin Paint: A Factor in Airless Sprayer Spitting

Thin paint can contribute to an airless paint sprayer spitting. When it comes to using an airless paint sprayer, inadequate preparation and viscosity control are essential factors to consider.

If the paint is not properly prepared or if its viscosity is too thin, it can lead to spitting issues. Inadequate preparation includes not properly mixing the paint, failing to strain it to remove any impurities, or neglecting to thin it if necessary.

Viscosity control refers to ensuring that the paint has the right consistency for spraying. If the paint is too thin, it can cause the sprayer to spit and create an uneven finish. Therefore, it is crucial to follow the manufacturer’s guidelines for preparing and controlling the viscosity of the paint.

Improper technique, which will be discussed in the following section, is another factor that contributes to paint spitting issues.

Improper Technique: Contributing to Paint Spitting Issues

Using the airless paint sprayer incorrectly can result in spitting issues. To avoid these problems, it is crucial to learn and practice the proper spraying technique. Here are three key aspects to keep in mind:
