Color Field Basics: Acrylic, Enamel & Lacquer Paint Layering

One common question we often receive from model builders is:

The answer depends on the type of paint, the thinner or solvent strength, and how fully dried or cured the previous layer is. But as a simple beginner-friendly guide, it helps to understand the basic strength of the three common paint types used in model making.

Acrylic paint is generally the weakest.
Enamel paint is stronger than acrylic.
Lacquer paint is usually the strongest among the three.

Because of this, the safest layering rule is:

Simple Paint Layering Chart

This simple chart gives a general idea of which paint type can usually be applied over another paint type.

Note: This chart is a general guide. Actual results may still depend on paint brand, thinner strength, drying time, surface preparation, and how heavily the next layer is applied.

Why Lacquer Is Commonly Used as the Base Layer

In simple terms, lacquer paint is usually the best choice for the base layer if you plan to add enamel or acrylic details later. Once the lacquer layer is properly dry and cured, you can apply enamel paint, acrylic paint, panel lining, weathering, or detail painting on top with lower risk.

Acrylic paint, on the other hand, is more sensitive. If acrylic paint is used as the bottom layer, applying enamel or lacquer paint on top can be risky. The stronger solvent may soften, damage, or react with the acrylic layer, especially if the top coat is applied too heavily.

This is also why applying lacquer top coat directly over acrylic paint can be dangerous. It is sometimes possible if the acrylic layer is fully cured and the lacquer top coat is applied in very light mist coats first, but it is still not the safest method for beginners. A heavy wet coat of lacquer over acrylic can easily cause problems.

General Usage of Each Paint Type

Each type of paint has its own strength and suitable usage. There is no single paint type that is best for everything.

Acrylic Paints

• Easier to handle and clean up.
• More beginner-friendly for small touch-ups and basic painting.
• Usually less aggressive compared to enamel and lacquer paints.
• Suitable for hand painting, small details, and casual colour work.
• However, acrylic paint layers are generally more sensitive, so stronger paints or strong top coats on top may cause problems.

Enamel Paints

• Often used for panel lining, small details, washes, and weathering effects.
• Slower drying, which can be useful when you need more working time.
• Good for detail work over a properly dried lacquer base.
• However, enamel thinner can still affect weaker paint layers if applied too heavily.

Lacquer Paints

• Stronger and more durable once properly dried.
• Commonly used for main body painting and base colour work.
• Suitable when you want a tougher paint layer before adding details, panel lining, or weathering.
• Usually works well as the bottom layer before enamel or acrylic paints.
• However, lacquer thinner is strong, so it should be used carefully, especially over acrylic or enamel layers.

A Safe Beginner-Friendly Approach

For beginners, the easiest safe approach is:

This does not mean you must always use lacquer paint. Acrylic and enamel paints are still useful, depending on your working style and the effect you want to achieve. But if you are planning multiple paint layers, lacquer as the bottom layer is usually the safer starting point.

Always let each layer dry properly before applying the next layer. If you are unsure, test on a spare runner or plastic spoon first. This small test can save your model from paint reaction problems later.

Final Note

Each type of paint has its own characteristic, and the best choice depends on what surface you are painting and what final effect you want to achieve.

Model painting is not only about colour. It is also about understanding the material, the surface, and how each layer works together.
