However, with regular and thorough cleaning, your spray gun will always have peak performance. Furthermore, it’ll help to create a smooth, even application that will make your finished project look fantastic. Read our short yet helpful guide on how to clean your HVLP spray gun.
Why Clean Your HVLP Spray Gun?
Cleaning your spray gun after every use will keep it in optimal shape. It will also provide the best possible results for every project, both large and small.
To get started, you will need:
- Solvent (e.g. water, or lacquer thinner)
- Cleaning buckets (for waste disposal and soaking parts)
- Cleaning brushes and picks
- A wrench
- Spray gun lubricant
- Safety gloves
- Rubber gloves
Firstly, you will need to pour out any remaining material from the cup. Clean out any residue with a solvent soaked rag. After you've done this, remove the filter at the base of the pick-up tube before following these simple steps.
- Fill the cup up to the halfway mark with your solvent. Tighten the lid and swirl the solvent around.
- Next, attach your spray gun to the house turbine and spray the solvent out into a waste bucket. You will need to repeat this stage until the solvent runs clean. Empty out any residual solvent into the waste bucket.
- With a clean rag, wipe out the inside and outside of the cup. Be sure to include the lid.
- Next, inspect the pressure tube and valve. Here you'll need to to see if there’s any debris that could dry and obstruct the airflow. If necessary, replace the wearable part. Make sure that the nipple attachments are always clean.
- Now remove the collar, air cap, and the needle. Unscrew the fluid control knob to remove the cap. Carefully remove the knob and gently squeeze the trigger to get the needle out.
- Use a wrench to remove the fluid nozzle from the front of the spray gun.
- Place the air cup, fluid nozzle, and needle into a container filled with solvent.
- Once all of the parts have been thoroughly soaked, use a cleaning brush to remove any debris from the small parts.
- Finally, use a cleaning brush or a rag to clean the needle.
Additional cleaning care
If you want to keep your spray gun clean, follow these additional cleaning care tips for the best results.
- If you have a gravity cup, you do not need to attach the spray gun to a turbine. You can instead, unwind the fluid knob at the rear of the gun and let the solvent stream out of the fluid nozzle.
- You should never soak the entire gun, only the parts. If you do, you will compromise the gun's efficiency.
- For the T-Model™, remove the air-diffuser, the diffuser seal, and the air divider in addition to the other parts. Allow these parts to soak in solvent for a few minutes.
- It is sometimes difficult to remove debris stuck in smaller holes. We recommend using a smaller cleaning brush for better access.
- Ensure that all passages in the air horns are clear. Here you could use small picks or pipe cleaners to clean these parts.
- Avoid using a wire or metal brush to clean your spray gun. This is because metal can cause damage to the parts.
