Acrylic Wash Vallejo Ammo Dark Wash – model paint wash for miniatures and scale models

Vallejo Ammo Acrylic Dark Wash is a ready-to-use water-based wash formulated to enhance shading and surface definition on miniatures, scale models and dioramas. Designed to flow into recesses, panel lines and textured surfaces, the dark wash increases perceived depth and creates controlled weathering without thick buildup. The pigment-rich, low-viscosity formula is compatible with common hobby paints and helps unify tones while accentuating fine details.

Advantages

This acrylic wash is ready to apply straight from the bottle and requires no thinning for most techniques. Its fluid consistency ensures smooth capillary action into crevices and along engraved lines, producing consistent shadows and subtle grime effects. Being water-based, it blends easily with other waterborne products, while pigments provide strong tinting and fast drying for efficient workflow during painting and finishing tasks.

Suitable for

• Enhancing panel lines and recesses on plastic and resin miniatures
• Adding weathering and streaking effects to scale models and diorama elements
• Bringing out texture in vehicle hulls, armor plates and architectural details
• Fine detail shading on figures, weapons and small accessories

Key specifications

• Formulation: water-based acrylic wash with high pigment concentration
• Finish: matte shaded effect suitable for layering and weathering
• Viscosity: low, designed for capillary flow into recessed areas
• Compatibility: works over acrylic and enamel paints once cured
• Application method: brush-applied; suitable for targeted or overall washes

How to use

Apply the acrylic dark wash with a soft round brush, directing the fluid into panel lines, joints and textured surfaces. After application, remove excess from raised areas using a clean damp brush or a soft cloth to leave only the desired shading. Allow adequate drying time between layers and before applying varnish or additional weathering products. For controlled results, test on a scrap piece first to assess drying time and color intensity.

Usage recommendations

Use in a well-ventilated area and keep the bottle tightly closed when not in use. Store at moderate temperatures and avoid freezing. When combining with other products, ensure underlying paint layers are fully cured. Clean brushes with water immediately after use.
