How to mix paint for HVLP sprayer? Do you have an idea for redecorating your home or creating an artistic masterpiece? Painting is one of the easiest ways to achieve this. 

You can pay a professional to do it, but you can also save money by learning how to mix paint for the HVLP sprayer.

HVLP guns have a reputation for being more efficient in paint transfer and less overspray. This guide will show you how to use latex paint to achieve this goal.

How to Mix paint for HVLP sprayer: Prepare Properly

You must first thin latex paint before you can use it. That’s because it’s thicker than other common paints and will not work properly with any HVLP spray in that state. 

It will not come out of the sprayer if you don’t thin it. Mixing latex paint and water in the correct proportions will prevent this from happening.

The process of thinning will be different for each brand. However, the water needed to do so will vary. Mix 10% water with the paint.

If it appears thicker than usual, add 5 percent water to thin the paint. Any paint should not be added to more than 25% water. A thin paint can cause problems with adhesion to the surface of the workpiece and will eventually fall off the surface.


Sometimes, thinning with water alone won’t work. To reduce viscosity, instead of adding water to exceed the 25% limit you can use a latex primer. The conditioner improves the paint’s viscosity but does not affect its adhesive properties.


When you are filling the HVLP sprayer reservoir, always use a standard paint strainer. This is because the nozzle measures only 1.4 millimetres in diameter and can easily get clogged with any small debris found in paints.

If the nozzle becomes blocked or clogged, it is best to remove the blockage and disassemble the gun. To remove any remaining fuel, you will need to filter it. You can use a strainer if you don’t have one.

Hose Length

The turbine produces heat when the HVLP runs. The heat is quickly dissipated if a short pipe has been used. 

During atomization, the incoming air transfers heat to the paint. Warm paint drys faster and doesn’t have enough time to spread or level out. 

It does not penetrate cracks to hold itself firmly. A six-foot pipe allows air to cool, and thus alleviates the problem.


The gun’s tip should be held eight inches away from the surface. This allows for the spray pattern to transfer maximum paint and minimize waste. 

Start at the top, then work your way down. Paint horizontal surfaces first, then move to the other side.

Before you move on to the next section, make sure it is fully wet. Otherwise, you’ll have to spray parts that have received less spray. 

This will make your entire job look amateurish when it dries. It is also wasteful and time-consuming to continue painting.

Try it out!

The factors for giving the paint the right viscosity are temperature, turbine output, humidity, the paint’s physical characteristics. 

Before you can find the perfect mix, it will take several trials. You will need to test every spray on scrap paper or cardboard before you can get the best results.

You must keep track of the spray result and record any adjustments to the sprayer setting. You can keep track of the setting and consistency you achieve and refer to it whenever you purchase paint. 

This will save you money and reduce the amount of waste that comes with removing a complete paint job simply because it was not done correctly.

You will need to test several times before you find the perfect balance. Keep in mind that every paint is different. 

One brand’s paint may work well for another brand. We hope you found this article informative. We wish you every success in your artistic endeavours.


What paint to use on HVLP?

To be able to spray with the HVLP sprayer, the paint must be of the correct thickness. I only use water-based finishes I thin the paint using water. To ensure the paint is perfect for spraying, I use a viscosity cup when I mix it.

What is the ratio of paint to thinner for spray guns?

A 3:1 or 4:1 ratio of paint thinner or a similar ratio is suitable for general purpose thinning. It is important that the paint used does not exceed the paint used. It is important to keep the paint thinner than the amount you use. This can lead to a lighter colour on the final surface.

Do you need to thin paint for HVLP?

Quality latex paint can be thicker than other finishes. It must be thinned prior to being used as a spray finish. Lack of thinning can result in paint being sprayed from the gun in unattractive blobs, or even not at all. Mix the paint well with water before spraying.

How do you dilute acrylic paint for a spray gun?

Here are some suggestions:

  1. Put the paint in the bucket.
  2. For every gallon, add 1/2 cup water.
  3. Mix well.
  4. You can check the thickness of the paint by running it through a funnel. If the paint flows freely through the funnel it is thin enough.

What is better HVLP or LVLP?

The FPro LVLP spray gun technology can atomize difficult coatings with higher viscosities, waterborne, and faster flow rates than HVLP guns. The LVLP guns can apply coatings quicker, making them more suitable for large objects and high-production applications.
