How to clean a spray gun

Date: 31 August 2022 | Category: How to...

In order to achieve that perfect paint finish, you’ll want to ensure that you are adequately equipped. A high-performance spray gun is the ideal tool for the job, but to ensure the most consistent finish quality, what you also really need is an effective and efficient way to clean and maintain your spray gun.

Safetykleen’s parts cleaning services could be exactly what you need. It could cut your cleaning times by up to 70%, eliminate risk of expensive re-work and reduce your environmental impact by minimising VOCs (Volatile Organic Compounds).

Why should you clean your paint spray guns?

Safetykleen recommends cleaning spray guns immediately after every use, or at the very least between colour changes, to maintain efficient paint delivery and peak performance.

If you don’t clean your spray gun regularly, the accumulation of dried paint and clear coats can quickly reduce painting efficiency and finish quality, and since both dry very quickly, it is better to address this sooner rather than later.

Too much accumulated trace paint in your spray gun, will clog the air cap and fluid nozzle, causing it to become inefficient in its job, making the spray pattern inconsistent, and potentially even causing the gun to break. Frequent cleaning and servicing saves you the expense of component replacement and a great deal of time.

How do you clean a paint spray gun effectively?

The process many businesses follow when cleaning their paint spray guns after use is fiddly, labour intensive, and can be surprisingly wasteful:

  • Manually cleaning out the paint cup
  • Disassembling the body of the paint spray gun
  • Having to submerge the parts in a paint thinner
  • Taking the time to wipe down everything thoroughly
  • Reassembling the paint spray gun, and flushing it through

And regardless of how rigorously you follow that procedure each time, you can never guarantee optimal results.

There is a much easier way.

Paint spray gun cleaning FAQs

What types of spray gun are there?

There are 3 main types of Paint Spray Guns and they consist of airless, compressed air and HVLP. What you will often find is that air spray guns make use of concetrated high-pressure air, which atomizes fluids with precision, HVLP spray guns don’t have that power and so make up for this difference with more air and apply a softer spray with with the reduced air pressure, this ranges between 0.05 to 0.1 MPa (7–14 psi). There are also suction and gravity fed paint spray guns, the difference here is in the atomisation of the paint with the process automatised in a suction fed gun, this is the one most commonly known and used. Gravity fed guns feature the paint container on top of the gun and uses the natural force of gravity to feed the gun, offering a degree of control you don’t get with the suction fed gun.

What types of paint are spray guns used for?

Latex paint is most often used because of its shelf life, cost and quality longevity. You’ll find that modern latex paint can be used in a variety of different environments, contains a series of new synthetic resins that are compatible with water and can be found in a mutitude of different colours.

  • How often do you need to clean them? A better quality cleaning solution will make for better cleaning results and less cleaning overall.
  • How many different colours and types of paint you use in each gun? The more paints you need to use will determine how often you need to clean and the strength of the solution.
  • How much space do you have on site for the machine and also for any cleaning fluids you may need to store? Practicality vs performance will factor into the decision-making process, you will want the best equipment for the space you have available.
  • How will you dispose of any used paint thinners and spray gun cleaning solutions? Consider waste management and the most cost effective, eco-friendly and time saving way to deal with that.
