Description
Air Dirt is a rich, cool-toned brown formulated to simulate wet soil, packed earth, or aged wood—perfect for groundwork, base shading, or weathering. This airbrush-ready version provides smooth, even coverage right out of the bottle, allowing modelers to quickly layer dirt tones onto terrain, vehicle undersides, or figure bases with ease. It's slightly darker and more saturated than Earth, making it a perfect companion for creating depth and variation across scenic elements.

Color Description

A deep, neutral brown with hints of gray and charcoal, Air Dirt delivers a matte finish that reflects the texture and tone of soil, weathered fabric, or stained wood. It’s especially useful in military and historical modeling for replicating realistic earth tones on diorama surfaces or environmental details.

Historical Context and Usage

Dirt-colored surfaces were everywhere in history:

• Battlefields and rural roads across the Revolutionary, Civil, and World Wars were defined by mud, soil, and dust in tones like this
• Railroad yards, farm scenes, and industrial zones were often surrounded by compacted, oil-stained dirt
• Industrial settings and diorama recreations
• Military uniforms, tents, and boots quickly took on these tones in use, making it useful for both terrain and gear weathering

Dirt complements a wide range of neutral tones and works especially well for multi-layer scenic bases, where visual realism depends on color depth.

Modeling Use Cases

• Diorama groundwork, trenches, industrial settings and embankments
• Tank treads, vehicle undersides, and track splatter
• Infantry figure bases for any historical period
• Wood accessories like crates, fence posts, and wagons
• Weathering railroad ties, freight cars, and steel decks

Airbrushing Tip

Spray at 15–25 PSI. Use it as a base layer for muddy terrain or a post-shading tone under tanks and vehicles. For extra depth, dust with Earth or drybrush with Aged Concrete to create a textured, realistic effect.

Micro-Mark Acrylic Airbrush Thinner if needed for custom blending. Air Earth is available in the Airbrush Railroad Acrylic Paint Set.
