Do You Need to Prime Miniatures? Acrylic Primer Myths Busted

Priming miniatures is often debated. We separate acrylic primer facts from myths, covering white vs black primer, airbrush vs brush primer, and plastic models.
Quick answer
Yes, you should prime miniatures before painting. A thin coat of acrylic primer gives paint a consistent matte surface to grip, especially on plastic, resin, wood, and metal. Brush-on or airbrushed, the goal is a clean, even base—not a thick coat.
Myth: Primer is optional on plastic models
Plastic miniatures often feel smooth, and acrylic paint can struggle to adhere without a primer. A primer creates a matte surface that helps subsequent layers bond. Skipping primer may lead to paint rubbing off during handling or looking uneven. For plastic models, a water-based acrylic primer designed for multiple surfaces is a safe choice.
Myth: You need an airbrush to apply primer
Brush-on acrylic primers are effective and require no special equipment. They can be thinned for airbrushing if desired, giving you flexibility. The key is applying thin, even coats and allowing proper drying time. Whether you use a brush or airbrush, the primer's job is the same: provide a uniform base.
Myth: White primer is always better than black
The choice between white and black primer depends on your intended paint scheme. White primer brightens colors and is useful for light or vibrant schemes. Black primer creates shadows and depth, ideal for darker or metallic schemes. Neither is universally better; pick based on the final look you want.
Primer myths: verdicts
- Do you need to prime miniatures?: Yes, priming is recommended for plastic, resin, wood, and metal miniatures to improve paint adhesion and coverage. Always apply a thin, even primer coat before painting.
- Is brush-on primer as good as airbrush primer?: Brush-on acrylic primer works well and can be thinned for airbrushing. The application method matters less than achieving a smooth, thin coat. Choose the method you're comfortable with; both can yield good results.
- White vs black primer: which should you use?: White primer suits bright or light color schemes; black primer suits dark or shadowed schemes. Neither is inherently better. Match primer color to your planned paint palette.
