Different Types of Lacquer

Article - June 2, 2008

This week’s question comes from Larry, who just picked up an Earlex Spray Station 5000 and has a question about using different types of lacquer:

I just purchased an Earlex Spray Station 5000 and I’m very pleased with its performance thus far. I’ve sprayed shellac, water-based dye, and Deft brushing lacquer, all with good results. I’d like to get into spraying more lacquer because it looks great and dries fast, but all the options out there are confusing to someone new to spraying, like me. Post-catalyzed, pre-catalyzed, nitrocellulose, water-borne—what are the differences, and what should I start with? Do certain types work better in different climates? Are any brands better than others? Sherwin-Williams seems to have a wide selection, and they have stores everywhere. Any help would be greatly appreciated. Thanks for your wonderful website.

First off, congrats on diving into the world of spraying! It’s a game-changer, but yeah, the options can be overwhelming. Lacquers come with enough jargon to make your head spin, and the wrong choice can turn your beautiful project into a cautionary tale.

Before we get into the nitty-gritty, I highly recommend checking out a good finishing book by Bob Flexner or Jeff Jewitt. These guys know their stuff and can give you a deeper understanding of finishes than I can in a single post. But since you asked, here’s a nutshell guide to lacquers and how they behave.

Lacquer 101: Breaking It Down

Think of lacquer as falling into three main categories:

  1. Nitrocellulose Lacquer – The “everyday” lacquer. It’s what you’ll find at Home Depot or Lowe’s (Deft is a common brand). It’s inexpensive, easy to work with, and lays down a beautiful finish. The downside? It yellows over time, which isn’t great for light-colored woods unless you’re going for that vintage patina.
  2. CAB-Acrylic Lacquer – This is like nitro’s cleaner, fancier cousin. It’s made with acrylic resins, so it stays “water white”—meaning it won’t yellow over time. It’s more durable than nitro and just as easy to spray. If you’re finishing light woods or just want a more stable finish, CAB-Acrylic is a solid choice.
  3. Catalyzed Lacquers (Pre-Cat & Post-Cat) – This is where things get serious. Instead of curing just by solvent evaporation, these lacquers cure chemically—which makes them way more durable than nitro or CAB-Acrylic.
    • Pre-Catalyzed – The catalyst is added at the factory, making it user-friendly.
    • Post-Catalyzed – You add the catalyst in your shop, giving you more control but also a ticking clock (it has a short shelf life once mixed).
    • Downside? Both types have a limited shelf life even before mixing, so check those dates before buying.

My Recommendation

If you can get your hands on it, Sherwin-Williams Pre-Cat CAB-Acrylic lacquer is a fantastic option. It’s durable, non-yellowing, and has lower toxic off-gassing compared to traditional nitro lacquers. It was relatively new when I first used it, so availability might vary—but it’s worth asking about.

That said, nitrocellulose lacquer is still a great all-purpose finish, especially if you’re just getting started and want something widely available.

Spraying Lacquer: Know Your Conditions

Lacquer is an incredible finish, but it can be a diva when it comes to temperature and humidity.

  • Ideal conditions: Above 70°F with low humidity.
  • Cold weather? Forget it. Lacquer doesn’t like to cure properly when it’s too cold.
  • High humidity? You risk “blushing”—where moisture gets trapped, turning your finish cloudy. (Not a good look.)

If you live somewhere humid, you may have to wait for the right season or time of day to spray, or invest in a retarder to slow drying time and reduce blushing.

Final Thoughts

Which lacquer should you use? That depends on your priorities.

  • Want the easiest-to-find and cheapest option? Go with nitrocellulose.
  • Need something clear that won’t yellow? CAB-Acrylic is your friend.
  • Looking for durability and pro-level performance? Pre-Cat or Post-Cat lacquer is the way to go.

Sherwin-Williams is my go-to for lacquer, but there are plenty of other great brands out there. Try a few and see what works best for your setup.
