How to stop your paint spray gun from spitting
Spray paint spitting can be a frustrating issue, and it can quickly ruin an otherwise perfect paint job. However, there are a few simple tricks that can help you to avoid paint spitting altogether. Here’s how to stop your paint spray gun from spitting or dribbling on your next job.
Paint spray guns offer a fast way to achieve a quality finish, particularly when used with extensions. Spray gun extensions allow painters to work faster and provide greater reach, with less physical strain on the body. Unfortunately, with many spray gun extensions, paint spitting can occur when you let go of the trigger and power off. The following advice can help you to prevent spitting and continue to spray with extensions.

What is paint spitting?
Paint ‘spitting’ is the term given when a paint spray gun expels droplets or uneven bursts of paint during the painting process.
It can result in an inconsistent finish, wasted paint and the need for additional touch-ups and can occur more commonly when using a paint spray gun extension.
Why does paint spitting occur?
When using a paint spray gun, there is an instant shut-off when you release the trigger. However, when using an extension, there is a gradual decrease of pressure along the length of the extension when you release the trigger.
This can mean there is not enough pressure for correct atomisation and can cause to the remaining paint to dribble or spit.
How can I prevent paint spitting?
The good news is that with the right tools and accessories, paint spray gun spitting is entirely preventable.
The Graco CleanShot™ Shut-Off Valve is a unique, needle valve that shuts fluid off at the tip of the extension rather than the gun, mitigating and potential spitting issues with ease and efficiency.
