How to clean an HVLP spray gun after use?

Things you need to know before cleaning your HVLP spray gun

Cleaning an HVLP spray gun generally isn’t too difficult to do, but it is very important to do so for long-term maintenance and use.

It might be tempting to put it off for later, but cleaning the spray gun as soon as possible after using it is the preferred way because that really is the best way to avoid large issues down the line.

For instance, leaving paint in a gun can leave dry or clogged gun filters which will cause issues when trying to spray paint later on with a consistent pattern

Even if you give it a thorough cleaning job you still might not be able to fully remove all residue in which case buildup may occur inside the airbrush.

And again leads to problems when spraying more paint which will often result in the poor exterior quality of your workstation surface.

With various other tiny pieces like the rubber seals, valve screws, and O-rings included in the gun your paint is stored in, it’s important to make sure they are clean at all times to lengthen the life of your spray gun.

This is why we recommend cleaning them immediately after use to make sure everything will work right but.

Once you get rolling with this process it won’t be too hard for you to keep up each time. The method to use HVLP spray gun is also here in my blog.

Disassemble the spray gun with caution

When it comes to the process of how maintaining a high-volume, low-pressure (HVLP) spray gun, there are many variations that you should consider.

The first thing you’ll want to do is thoroughly research your unique HVLP gun – whether that be online or in your user manual – for a reference guide detailing how exactly your gun can be taken apart piece by piece.

There are so many reasons why it’s important to take good care of your gun. First, have you ever noticed that all guns are made up of different parts?

Most of them have triggers as well as clips for bullets and a bolt which is what helps the bullet be shot out when the trigger is squeezed.

But like anything else in this world, each gun has its own unique parts and purposes which means whenever you’re dealing with an array of guns.

You’ll want to treat them with a lot of care because otherwise, it will become very difficult if not impossible to put the guns back together again.

Take care of your disassembled parts

When people clean their guns, one of the most common mistakes that they make is not cleaning each part properly so as to not risk damaging them or rendering some of them useless.

They will simply put all the gun parts in a sink basin together and fill it with hot water and soap, which causes the liquid to mix with the contaminants from their gun, leading to a murky and unclear solution.

But this method doesn’t actually clean anything. By separating the small pieces of your gun away from the larger ones during cleaning, you can help to preserve its longevity.

Tools we need to clean our HVLP spray gun

Some cleaning kits contain a solvent, which will dissolve the paint that clogs your gun. Do you already have any of these items on hand? Check the list below to see whether or not you have them:

  • Soapy water for cleaning
  • Some kind of cleaning solution (Preferably Paint thinner)
  • Gloves for protection of hands
  • Goggles for protection of eyes
  • Cleaning brush for cleaning
  • Rags or paper towels for covering the surface
  • Buckets for water
  • Gun wrench for disassembling spray gun
  • Toothpicks for tight spots

One last bit of advice before we get started – make sure you protect yourself from any potential injuries.

It isn’t fun to deal with an injury due to a lack of protection, so be sure that you regularly update your cleaning equipment (especially if you’re working on something particularly rough or difficult).

These things can damage your health in the long run if they come in contact with unprotected parts of your body, so make sure you’re careful.

Cleaning the cap

The first step? Cleaning the paint cup! Usually, this part of the gun will have a lot of leftover paint or other liquids in it.

To clean the paint gun properly, you can use an air compressor. Once done, top up with your cleaning agent. Put on the color bottle and its handle and then pump it once to release all pressurized air.

Pull out the trigger, trying not to trigger it again while doing so but if you are to repeat pulling it out without pumping it first you might spray some thinner over your work surface or even worse into your eyes.

To make things as easy as possible when cleaning your spray gun, you should fill up the paint sprayer with thinner.

The thinner will loosen any dried paint pigment that might be hanging around inside the machine and allow some of it to work its way through the inner mechanisms of the spray gun.

To help aid this process, you should use a piece of paper towel with some thinner on it to run through the inside of the cup (while wearing protective gloves).

You want to remove any lingering pieces of paint from inside the main body of your spray gun. Additionally, you’ll want to clean off the inside of your cap with a paper towel and cleaner too.

Now disassemble the spray gun

The next thing is to take your paint bat off and set it down on a paper towel to dry. Then you take the rest of the gun apart.

First, unscrew the air cap and then you’re going to remember when I told you not to let any of these parts get lost.

So, hold onto them all very carefully in your hand or put them down somewhere where they can’t roll away okay?

And now with a wrench, you take off the inner part of the air cap and just those teeny tiny little pieces.

Submerge the disassembled spray gun in thinner

Once the spray gun has been taken apart, you’ll want to clean each piece individually.

We recommend using paint thinner because it makes the work easier, but you could also use a simple cleaning solution or soap and water if you wish to switch it up.

The important thing is that all the pieces are cleaned properly so they don’t get damaged in the process.

It’s easy enough to take care of these smaller parts if you know what you’re doing and if you put a little bit of effort into learning how despite its simplicity.

First of all, you’ll want to separate the pieces into groups. This will help prevent lost parts. You won’t want any of those springs or needles to get in with the main body or you’ll have to take it apart again to find them!

Now pour a little paint thinner into your plastic cup and dunk each piece fully inside.

Allow it to soak for about a minute as that will give enough time for most of the paint residue inside of these little nooks and crannies to be dissolved.

I’m sure you’ve noticed already but just in case, there’s no need to let your spring get soaked along with everything else as you can actually clean it with a toothbrush without removing it from that rod

Wipe everything properly

After you’ve given your cleaning solution a minute or two to settle, it’s time to take the tank and atomizer pieces out of the bottle that you mixed them in and start getting ready to wipe them down.

This is where some gentle bristles cleaning brushes come into play as well as some thin toothpicks.

Use the brush to thoroughly clean your drip tips; they should be much easier to clean now having had some time have settled.

Some people like to use their thumb after they’ve been cleaned if they are still feeling a little slippery but we don’t recommend doing this too harshly because you shouldn’t be pressing too hard on it in order for it not to cause permanent damage or wear and tear on it.

You may find that taking just a little bit of alcohol on a paper towel will do the trick for you if there is still any residue leftover from your liquid.

After you clean the ridges and do the inside, you then use a toothpick to clean each ridge on the needle and spring.

The grooves are really hard to reach, so don’t let that discourage you. Take your time and re-clean anything that is still dirty after a few meticulous attempts.

Reassemble the sprayer

Afterward, you’ll assemble the spray gun. First, you place the needle and spring it back into its rightful place.

Next, you screw on the inner air cap while also making sure to insert your outer air cap as well. You’ll then put your paint cup back on your spray gun and replace its lid before that!

FAQ’s

You can use Mineral Spirits to clean the exterior surface of an airless spray gun. However, you should not use mineral spirits when cleaning the tip of the airless spray gun’s nozzle. What you should do is use a needle to clean the nozzle of the airless sprayer gun tip. When you are working with the mineral spirits to clean the exterior surface of the airless spray gun, you need to wrap the airless spray gun in a plastic bag, and then put the airless spray gun in the mineral spirits to make it work.

Yes, you can run paint thinner through a paint sprayer. But I don’t recommend it. Many paints have a chemical reaction to paint thinner and are ruined. Before you decide to go ahead with it, find out what the manufacturer says. It could be they recommend against it. When you thin your paint, you’re basically changing the viscosity. If the viscosity is too thin, the paint will be too watery and can result in a weak paint job. If the viscosity is too thick, the paint will be too thick and take too long to dry. It can also clog your sprayer. Also, keep in mind that thinning your paint will cut your coverage rate and cause you to need to use more paint, which will cost you more money no matter how cheap the paint is.

The short answer is yes. The longer answer is…it’s not necessary to clean the HVLP gun between coats, but it should be done if you want to improve the quality of your finish. Read on to learn more. HVLP spray guns actually have what is known as a “pause” function. The reason for this is that you don’t need to be using the gun constantly as you work. A constant flow of paint will settle the paint and make it rough; this is bad for your finish. So to keep things even, HVLP guns will automatically shut off periodically to let some of the paint settle. If you’re going to clean your gun, do it at the end of a project or when the gun is running idle. You could probably spray a few coats between cleanings, but if you’re working on a large project, it’s probably safer to clean it as you go.

Yes, turpentine is capable of cleaning your paint gun. Turpentine is a flammable liquid used to clean paint brushes, rollers, and other paint equipment. It is the cheapest of all the solvents used for this purpose. It is capable of removing paint from most surfaces, including wood, tools, metal, and even concrete. Using turpentine to clean paint off a paint gun is quite difficult. The reason for this is that the paint is on the metal and not the surface you wish to clean. This means that you will have to use turpentine to clean the paint off the paint gun.  An easier way to clean your paint gun is to use water. Water dissolves the paint. Some paint guns have a metal reservoir that is easy to clean. However, most paint guns have a plastic barrel which is extremely difficult to clean. To clean a paint gun, first, try to flush it out with water. You can use a garden hose to do this. Once the paint gun has been flushed out, use a special solvent to remove the residue.

Final Thoughts on How To Clean HVLP Spray Gun

So, here is the complete guide on how to clean your HVLP spray gun with step by step guide so you don’t make any mistakes during the process of cleaning and get satisfactory results.

If you have any queries regarding this post then let me know in the comments section so I can solve them and clear out your confusion regarding that specific problem.

Cleaning an HVLP spray gun will quickly become one of your favorite parts of the painting. It’s much easier to do it right the first time than to have to correct a mistake down the line!

Here’s how to do it: To start, turn off the compressor and unplug the gun from the electrical outlet. Next, remove all larger pieces that may be slowing down its performance like dirty cups or flaps under the paint tips.

After removing these things, thoroughly clean any bits that might still have clinging paint residue on them. You can do this by mixing some solvent with warm water in a sponging pot, submerging the pieces in it, and rubbing gently but firmly with a paper towel until all of the old pieces are gone.

Lastly, allow hot water to run through the bit holes for about five minutes before blasting air through them with your compressor again. Now you’re ready to paint once more!

Sometimes it’s a really real bummer when you get the paint on yourself. This can happen when the nozzle starts to clog or if there is a buildup on the paint gun itself.

So as much as possible, try to avoid getting leftovers of your beloved craft project all over yourself (unless it’s some kind of crazy art project that purposefully requires it).
