Various factors can cause malfunctions and defects on an Airless paint spray gun. In the following article we give an overview of the most common problems you may face when your Airless spray gun malfunctions or is damaged and make suggestions to help you repair the Airless spray gun yourself.
List of defects
- Gasket of airless paint spray gun clogged or worn
- Clogged filter in the handle of the gun
- Nozzle seal is missing on the Airless gun or is defective
- Lost and clogged nozzles on Airless paint spray guns
Gasket of Airless paint spray gun clogged or worn out
Nothing lasts forever, least of all the locking mechanism of an Airless spray gun. In the picture below marked in red is the seal / repair kit of an Airless spray gun. This locking mechanism can become clogged or worn out over time. If paint or other material remains in there (likely due to improper cleaning), the mechanism of the gun can be disturbed and the gun can no longer close properly.
Wear and tear can also damage the lock function and cause the gun to malfunction. Under normal operation, the gun will spray paint as soon as the trigger is actuated. If you let go of the lever, the paint or material supply is stopped and no further material is injected. Due to blockage or wear of the seal, this mechanism may not work optimally. In this case, the spray gun continues to spray paint, although the trigger has already been released. This makes the controlled application of paint with this gun impossible and the gun must be cleaned, repaired or replaced.
Clogged filter in the handle of the gun
In the handle of an Airless spray gun is a filter. This filter is used to filter out impurities in the paint and prevent clogging of the spray tip. If this gun filter is not regularly cleaned or replaced, it can get clogged and block the entire paint supply. In this case, the filter is so heavily covered with material that no further color comes through the mesh.
If no material is pumped through the gun, so the gun filter should be checked and cleaned or replaced.

Tip: When using spray gun with plaster no filters are installed!
Nozzle seal is missing on the Airless gun or is defective
We receive regular calls and requests for guns that lose color at the front of the nozzle or nozzle holder. This is usually not a damage to the gun, but a problem with the seals between the gun, nozzle holder and nozzle. This seal consists of a crescent-shaped metal and a plastic seal. If these seals are missing, incorrectly inserted or damaged, the paint and the nozzle holder may leak laterally. Here in the video the correct assembly of the nozzle seals on a Graco spray gun is presented.

Tip: The seals are often lost when cleaning the gun. Therefore, pay attention to the seals during cleaning and it is best to store replacement seals.
Lost and clogged nozzles on Airless paint spray guns
Worn or clogged nozzles can also interfere with the function. Dirt or dried paint residues can clog the nozzle. Already glued airless nozzles can be cleaned with special nozzle needles. Containers for storage and preservation of airless nozzles prevent the sticking and drying of paint and paint residues in the nozzle (Wagner TipClean and FARBMAX nozzle cleaner).
Worn nozzles should be replaced in time as the nozzles will wash out over time. This will make the spray pattern and color distribution uneven. In addition, it leads to increased color fog and the material consumption increases significantly. Therefore, it makes economic sense to regularly replace the nozzles, as the increased ink consumption significantly more expensive than a new nozzle. After how many liters of ink a nozzle should be changed depends on various factors (eg viscosity, solids content of the ink, pressure setting), therefore no clear service life can be named. When spraying, you should therefore keep an eye on the spray pattern and, if necessary, match the spray pattern of a new nozzle.
