Why is My Paint Sprayer Spitting
There are several potential causes of spitting paint from a spray gun.
Using Excess Thinner
One common cause of spitting paint is over-thinning the paint. This can occur if too much thinner is used, or if the paint itself is too thin. When this happens, the paint doesn’t have enough body to resist the pressure of the spray gun, and it is forced through the tip in a fine mist. This causes the paint to spit out in an irregular pattern.
Not Using Enough Thinner
Another potential cause of spitting paint is not using enough thinner. If the paint is too thick, it won’t flow through the spray gun tip properly. This can cause the paint to come out in clumps, or to spit out in an irregular pattern.
Improper Tip Size
If the sprayer tip is too small for the job, it can cause paint to spit. The tip needs to be the proper size for the amount of paint being sprayed. If it is too small, the paint will be forced through the tip in a fine mist, causing it to spit out.
A dirty sprayer can also cause paint to spit. If the spray gun isn’t clean, the paint can build up on the sides of the cup or on the tip, and this can cause the paint to come out in clumps or to spit out in an irregular pattern.
Dirty or Clogged Filter
A dirty or clogged filter can also cause paint spitting. The filter helps to keep the paint from clogging the spray gun, and if it is dirty or clogged, the paint can’t flow through properly. This can cause the paint to come out in clumps or to spit out in an irregular pattern.
Another potential cause of paint spitting is improper technique. If the sprayer is held too close to the surface, the paint can be forced through the tip in a fine mist. This can cause the paint to spit out in an irregular pattern.
Obstruction in the Nozzle or Hose
An obstruction in the nozzle or hose can also cause paint spitting. If there is something blocking the flow of paint, it can cause the paint to come out in clumps or to spit out in an irregular pattern.
These are just some of the potential causes of paint spitting. If you are having this problem, it is important to troubleshoot the issue to determine the cause so that you can fix it.
How to Prevent a Spray Gun Spitting
If you’re using a paint spray gun, one of the last things you want to happen is for it to start spitting paint. Not only is it annoying, but it can also ruin your paint job. So what can you do to prevent spray gun spitting?
There are a few things you can do to prevent your paint spray gun spitting:
– Make sure the paint pressure is set properly. If the pressure is too high, it can cause the paint to spit.
– Use a thinner paint. Thicker paints are more likely to clog the paint spray gun, which can cause spitting.
– Clean the paint spray gun regularly. A clogged paint spray gun is more likely to spit paint.
– Use a high-quality paint spray gun. A cheap paint spray gun is more likely to have problems, including spitting paint.
What to do if your paint sprayer starts spitting while you’re using it
If your paint spray gun starts spitting while you’re using it, there are a few things you can do to try and fix the problem.
1. Check the Paint Cup
One of the most common reasons paint sprayers start spitting is because there is something blocking the paint cup.
2. Check the Filters
Another common reason paint sprayers start spitting is because the filters are dirty or clogged.
3. Check the Nozzle
If the paint spray gun is still spitting after you’ve checked the cup and filters, it’s possible that the nozzle is blocked.
If none of the above solutions fix the problem, you may need to clean the paint spray gun.
Follow the manufacturer’s instructions on how to properly clean the paint sprayer. This may require disassembling the paint sprayer and cleaning each individual part.
5. Check Air Pressure
If the paint sprayer is still spitting after you’ve tried all of the above solutions, it’s possible that the air pressure is set too high. Turn the air pressure knob to the left until the spitting stops.
If your paint sprayer continues to spit after trying all of these solutions, you may need to take it to a professional for further troubleshooting.

1. Type of Paint Sprayer
The first thing you need to consider is the type of paint sprayer you need. There are two main types of paint sprayers: airless and HVLP.

3. Nozzle Type
Another thing to consider is the type of nozzle you need. There are three main types of nozzles: flat, cone, and fan. Flat nozzles are best for spraying large areas, while cone and fan nozzles are better for smaller areas.
Finally, you need to consider the price of the paint sprayer. Paint sprayers range in price from a few hundred dollars to several thousand dollars. Choose a paint sprayer that fits your budget and your needs.
5. Tips for Using a Paint Sprayer
Once you’ve chosen the right paint sprayer, there are a few things you need to keep in mind when using it. Here are some tips for using a paint sprayer:
– always use fresh paint;
– always thin the paint before spraying;
