Vallejo Surface Primer Color Black 60 ml
The Vallejo Black Primer is a first coat designed to help model surfaces accept subsequent paints. It recommends degreasing the model, then applying successive coats to form a hard, durable film. Best for hobbyists who want a fast-drying, matte primer suitable for airbrushing or brushed application.
Who it’s best for: painters priming dark-toned figures or aiming for bold shadows under color layers. Why selected: consistent matte finish and quick drying support rapid workflows.
Caution: avoid heavy layers that obscure fine details; apply in thin coats for best edge definition.
Vallejo Surface Primer Color White 60 ml
This white primer provides a bright base that makes light colors such as yellows and pastels pop. It emphasizes surface preparation for adhesion and encourages a clean, uniform finish after spraying or brushing. It’s part of Vallejo’s airbrush-ready primer family and dries quickly for efficient painting sessions.
Who it’s best for: miniature painters prioritizing light base colors and vibrant topcoats. Why selected: reliable adhesion and a crisp white base ideal for high-contrast color schemes.
Caution: white primers can show brush strokes if applied too thickly; thin coats improve smoothness and detail retention.
Vallejo Surface Primer Color Grey 60 ml
The Grey Primer offers a middle ground between white and black primers, helping to balance tones before color layers. It forms a smooth, quick-drying film that’s suitable for airbrushing or brush-on application and supports even topcoat color development.
Who it’s best for: painters who want a versatile neutral base for mid-tone painting. Why selected: it reduces color shift when layering mid-range colors over the primer.
Caution: ensure the surface is thoroughly degreased; any oil residue can hinder adhesion and finish quality.
The Army Painter Warpaint Fanatics Brush-On Primer
This brush-on primer is designed for precise color control with features that support detailed miniature work. A mixing ball helps blend colors smoothly, while a spill-free dropper enhances paint management. It’s described as ideal for hobbyists who want predictable results with minimal waste.
Who it’s best for: detail-oriented painters and hobbyists who prefer brush-on primers for fine work. Why selected: the mixing ball and dropper support consistent coverage and color matching.
Caution: brush-on primers can require additional coats for large surfaces; plan for multiple thin applications to avoid pooling and brush marks.

Buying Guide: What To Look For In Brush-On Primers
Primer selection depends on the painting workflow, model type, and finish preference. Here are practical considerations to help you choose wisely.
- Finish and sheen: Matte finishes reduce glare and enhance color adhesion, while satin or gloss can affect how topcoats lay down. For most miniatures, a matte primer is preferred.
- Application method: Brush-on primers are ideal for controlled coverage and spot priming on small areas. If you use an airbrush, ensure the primer is compatible or dilutable for spray application.
- Color base: White bases brighten colors; black bases deepen shadows; gray bases offer a balanced starting point for mid-tone painting. Consider the color family of your final topcoats.
- Drying time and odor: Fast-drying formulas save time, but ensure proper ventilation when using any solvent-based primer. Water-based primers are common for hobby kits and are less odorous.
- Adhesion and surface prep: Primers bind best when the surface is clean and free of release agents. Degreasing and dry surfaces improve adhesion and edge sharpness.
- Detail fidelity: For fine details, consider primers that go on smoothly in thin layers and do not obscure micro-details. Layering is often preferable to heavy coats.
Frequently Asked Questions
- What is the main advantage of brush-on primer over spray primer?
Answer: Brush-on primers offer direct control over coverage, especially on small or hard-to-reach areas, reducing overspray and enabling spot priming. - Can I use brush-on primer for plastic and metal miniatures?
Answer: Yes, most brush-on primers in this group are designed for plastic and metal models, but always check the product’s surface compatibility. - Should I degrease models before priming?
Answer: Yes. Degreasing removes release agents and oils that can hinder adhesion and result in uneven finishes. - Is white primer better than black for all models?
Answer: Not necessarily. White is ideal for bright topcoats and lighter schemes, while black suits darker highlights and shadows. - How many coats are needed for good coverage?
Answer: Start with one thin coat, inspect, and apply additional thin coats as needed to avoid pooling and preserve edge details. - Can I mix primers or dilute them for brushing?
Answer: Some primers are designed to be diluted with airbrush thinner or flow improver; follow the product guidelines to maintain film integrity.
