How To Clean A Clogged Wagner Paint Sprayer

What can cause a Wagner paint sprayer to clog?

Several reasons could cause your Wagner paint sprayer to become clogged, including using paint or material with too much viscosity, failing to clean the paint sprayer after each use, using an incorrect nozzle size for the particular job, not thinning latex- or acrylic-based paints.

Using paint or material with too much viscosity is one of the most common causes of clogging in Wagner Paint Sprayers. When selecting a paint or material for use with your Wagner Paint Sprayer, it is essential to check the viscosity level, as this can affect how well it sprays. The best practice is to thin any latex- or acrylic-based paints before use, as these require thinner consistency than other paints.

Failing to clean your Wagner Paint Sprayer after each use can also cause clogs. To ensure optimal performance, following the manufacturer’s instructions and cleaning the paint sprayer after every use is essential. This will help prevent any residue from drying inside the nozzle and causing clogging issues.

Using an incorrect nozzle size for a particular job can also lead to clogging. Each nozzle size is designed for a specific painting job, so select the correct one before beginning a project. Using too large a nozzle can cause paint or materials with higher viscosity levels to become clogged in the tip. Using too small a nozzle can result in inadequate coverage of the painted surface.

Finally, not thinning latex- or acrylic-based paints before use can also clog your Wagner Paint Sprayer. These paints require a thinner consistency for spraying; clogs can result if they are not correctly thinned before use. Follow the manufacturer’s instructions regarding paint thinning when using these paints with your Wagner Paint Sprayer.

It is essential to regularly clean your gun and nozzle to ensure it performs at its best. Use a cleaning solution designed for guns and nozzles for the best results. Here are the steps for how to properly clean the gun and nozzle:

Safety Considerations:

Before you begin, ensure the gun is unloaded and the power switch is off. Also, ensure that all parts are free of dirt or debris before cleaning. Wear protective gloves while handling any chemicals or cleaning solutions.


Carefully disassemble the gun and nozzle according to manufacturer instructions. Place each part on a clean cloth that won’t disturb during the cleaning process.

Cleaning Solution:

Mix a small amount of your chosen cleaning solution with warm water in a bowl, bucket, or other containers large enough for all the parts. Ensure to follow label directions for dilution rate and safety precautions listed on the solution’s label.


Soak the gun and nozzle parts in the cleaning solution for at least one hour, occasionally stirring to ensure that all areas are being exposed to the cleaning solution. Use an old toothbrush or soft-bristled brush to remove tough spots or debris that did not come off during disassembly.


Thoroughly rinse each part with clean water. Remove any lingering residue from the cleaning solution before reassembling everything back together.


Allow all parts to air dry on a clean cloth before reassembling and storing your gun and nozzle.
