Acrylic vs Lacquer: The Simple Trick to Improve Your Model Kit Finish Right Now

We’ve all been there. You spend days (or weeks) perfecting a 3D print. You’ve sanded the resin until it’s smooth as glass, or you've carefully prepared a 1:6 scale droid kit. You reach for your trusty acrylics, start painting, and… it looks okay. But it doesn't look factory. It doesn't have that deep, "used universe" durability you see on professional studio models.

If you’ve been wondering why your finishes aren't quite hitting the mark, the answer usually boils down to a classic hobbyist debate: Acrylic vs Lacquer.

At Redflare Model Studio, we’ve seen thousands of builders tackle our 3D printed model kits, from the tiny scurriers in 1:18 scale to massive 1:6 scale character builds. Through years of testing, we’ve found a "simple trick" that bridges the gap between these two paint types. It’s the secret to getting a finish that is both incredibly durable and hyper-detailed.

Let’s dive into the world of model paints and see how you can level up your next build.

The Contenders: Acrylic vs Lacquer for Model Kits

Before we get to the "trick," we need to understand the tools. If you’re looking for the best paint for 3D printed models, you’ll mostly be choosing between these two.

Acrylic Paints: The Community Favorite

Most of us start with acrylics (like Citadel, Vallejo, or Army Painter). They are water-based, low-odor, and incredibly easy to clean up.

• Pros: Safe to use indoors, huge color range, and they dry fast. They’re perfect for brush painting fine details on things like our Massiff models or character head sculpts.
• Cons: They don't "bite" into the resin or plastic very well. Acrylics sit on top of the surface, making them prone to scratching or peeling if the piece is handled frequently.

Lacquer Paints: The Professional Standard

Lacquers (like Tamiya LP or Mr. Color) are solvent-based. They are "hotter" than acrylics, meaning the chemicals actually melt slightly into the surface of the model.

• Pros: Incredibly tough finish. They level out beautifully, leaving a thin, smooth coat that doesn't obscure the tiny details on a 1:12 scale droid unit.
• Cons: They smell! You absolutely need a respirator and good ventilation. They are also much harder to use with a traditional brush; they are designed almost exclusively for airbrushing.

The Simple Trick: The "Paint Sandwich"

Here is the secret used by pro-builders and studio artists: You don't have to choose one or the other.

The best way to improve your finish right now is to use Lacquer for your base, and Acrylic for your details.

Why this works

Lacquer is the "hottest" paint, and Acrylic is the "coolest." In the world of model kits, there’s an unspoken law: Never put a hot paint over a cool one. If you spray lacquer over acrylic, the solvent in the lacquer will eat the acrylic layer and ruin your work.

However, if you do the opposite, putting Acrylic over Lacquer, you get the best of both worlds. The lacquer base coat provides a rock-solid, smooth foundation that won't budge. You can then use acrylics for all your weathering, washes, and fine detailing.

The "Simple Trick" Workflow:

1. Prime with Lacquer: Use a high-quality lacquer-based primer. It will fill micro-pores in the 3D resin and create a bond that won't chip.
2. Base Coat with Lacquer: Spray your main color (like the grey of a Steelpecker) using lacquer paint.
3. Weather with Acrylic: This is the fun part. Because the lacquer base is so tough, you can apply acrylic washes or "chipping" effects. If you make a mistake? You can wipe the wet acrylic off with a damp cloth without affecting the lacquer base coat underneath.

This gives you a level of control that you just can't get using acrylics alone.

Why 3D Printed Resin Needs Extra Care

If you’re building kits from our shop, you know we specialize in high-detail resin prints. Whether it's a Kusak or a Nydak, 3D resin is much denser and smoother than traditional injection-molded plastic.

Because resin doesn't have the same "porosity" as plastic, paint adhesion is the number one struggle for customizers. Using the lacquer base method ensures that your paint doesn't just flake off the first time you try to pose your figure or move your diorama.

Scale Matters: 1:6 vs 1:18

The scale of your model also changes how you should approach your finish:

• 1:18 Scale (3.75"): These are tiny! Every layer of paint counts. Lacquers are thinner than acrylics, so using a lacquer base prevents you from "clogging" the details on small creatures like Scurriers.
• 1:12 Scale (6"): This is the sweet spot for the "Sandwich" trick. Most Black Series or Vintage Collection customizers use this method to ensure their droids look screen-accurate.
• 1:6 Scale (12"): For larger builds, like our Ronto, a lacquer base is essential for durability. A large model has more surface area to get scratched, don't risk it with a weak paint job!

Step-by-Step: Getting the Pro Finish

Ready to try it? Here is our recommended workflow for any Redflare kit.

1. Prep is Paramount

Before a drop of paint touches the resin, you need to prep. Even the best lacquer won't stick to uncured resin or dust.

• Check our Assembly Instructions for tips on cleaning and sanding.
• Wash the kit in warm soapy water to remove any lingering resin oils.
• Dry it thoroughly. (Seriously, wait an extra hour. Moisture is the enemy.)

2. The Lacquer Foundation

Set up your airbrush (or use a high-quality rattle can like Tamiya Fine Surface Primer). Apply 2-3 thin coats. You want to see the "sheen" of the resin disappear, replaced by a smooth, uniform matte or satin finish.

3. The Acrylic Magic

Once your lacquer base is dry (usually within 30 minutes), you can switch to your acrylics. This is where you bring the model to life.

• Dry Brushing: Pick out the scales on a Bograt or the fur on a Wyyyschokk.
• Washes: Mix a dark acrylic wash and let it settle into the recesses. Since your base is lacquer, you can use a cotton bud to "clean" the highlights without stripping the base paint.

4. Sealing the Deal

To finish, we always recommend a final clear coat. A matte lacquer clear coat will unify the different textures of the acrylic and lacquer layers, making the whole thing look like a single, solid object.

A Quick Safety Note

We love this hobby, and we want you to stay healthy doing it! Lacquers contain strong solvents. Please, please review your safety gear before ordering your first batch of lacquer paints.

• Respirator: A simple dust mask isn't enough. You need one rated for organic vapors.
• Ventilation: If you don't have a spray booth, work outdoors or near a very large open window with a fan.
• BTW: If you're painting in a shared living space with no ventilation, stick to high-quality acrylic primers instead. Safety first!

Summary: Which is the Best Paint for 3D Printed Models?

The truth is, neither is "the best" on its own. The real winner is the combination.

By using Lacquer for durability and Acrylic for detail, you’ll find that your painting sessions become less frustrating and more creative. You’ll stop worrying about the paint chipping and start focusing on making your Star Wars dioramas look as realistic as possible.
