Lacquer paint is typically used as a finish on wood furniture and car bodies. It dries quicker than other finishes, but can you apply it with an HVLP sprayer to get the job done even faster?
Use this guide to find out everything you need to know about spraying lacquer with HVLP guns on your next project.
Lacquer is resin emulsified in a solvent. For example, nitrocellulose generated from wood pulp is the resin, and it's mixed with chemical solvents to help it spread over a surface and pigmentation for coloring.
HVLP stands for “high volume low pressure,” which is how these paint sprayers operate: lots of paint sprayed at low pressure. By contrast, LVLP sprayers emit a low volume at low pressure.
LVLP sprayers are better for high-viscosity materials, while HVLP sprayers work best for less viscous applications like lacquer.
Compared to other finishers like polyurethane, tung oils, and shellac, lacquer has a thinner consistency, which means it runs through an HVLP sprayer more easily and dries much faster.
Most DIYers use HVLP sprayers to add a protective layer and sheen to wood furniture. However, it is also used as a sealant and coloring agent on metal, plastic, and synthetic materials.
Lacquer is generally either pre-catalyzed, meaning the manufacturer adds the catalyst, or post-catalyzed, which means the user adds the catalyst right before use. Either kind will work if you’re using an HVLP spray gun for lacquer, but post-cat will have a few extra steps and doesn’t last as long in the can.
Spraying pre-cat lacquer with HVLP guns is faster than brushing and leaves a much smoother finish. You need to build coats, applying a little lacquer at a time until you reach the finish you want.
The ideal tool is a paint sprayer with a 1.8mm air cap and an air compressor that provides a minimum of 9CFM at 90 psi. Once you’ve got the right sprayer, use the guide in the next section to learn how to spray lacquer with HVLP sprayers.
Spraying Lacquer With HVLP Gun (How-To Guide & Expert Tips)
You may need to thin your lacquer before you get started, particularly if it’s a post-cat mix.
Thinning your lacquer isn’t complicated at all, but you’ll need a few things before you get started with that.
Once you have all these things, follow these steps to lacquer your project with a paint sprayer:
- 1Get set up. Put on your respirator, turn on the fans, and clear the area where you’ll be spraying to prevent the cable from getting caught.
- 2Remove the paint reservoir and place the filter inside. Mix the paint so that any binders or pigments are evenly distributed. If they aren’t evenly dispersed in the can, they won’t be on your finished project, either.
- 3If you’re using pre-cat, fill the reservoir about 85% of the way. If you’re using post-cat, fill it up 65 - 75% and fill the remainder up to 85% with thinner. Stir the contents of the reservoir, then attach it to your sprayer.
- 4Set whatever you’re lacquering in a paint booth or set it on a flat surface where paint splatter won’t matter.
- 5Turn on your air compressor and aim the sprayer away from the object. Hold the trigger down until paint is passing through, then start lacquering your object.
- 6You want to cover a good distance from every angle so that the last spray in the coat overlaps earlier sprays by a significant margin - on the surface of a table, for instance, you might aim for that last spray to overlap by as much as 50%
- 7You want to cover a good distance from every angle so that the last spray in the coat overlaps earlier sprays by a significant margin - on the surface of a table, for instance, you might aim for that last spray to overlap by as much as 50%

The optimal HVLP tip size for lacquer paint is a 1.8mm air cap. It’s large enough for a good amount of lacquer to get through but not so wide that you’ll get tons of overspray. A clean 1.8mm will give you that flawless finish you’re looking for.
