Acrylic Weathering Wash VALLEJO Russian Mud – Brown, 1 pc (2021330)

VALLEJO Russian Mud is an acrylic weathering wash formulated to reproduce brown mud and grime on scale models, miniatures, vehicles and diorama terrain. Supplied as a single 1-piece pack, this wash enhances surface detail and panel lines by settling into recesses and creating natural tonal variation. The product is part of a diorama effects range intended to connect models to their environment, simulating everything from wet mud to dry earth found in varied landscapes.

Advantages

This acrylic wash offers controlled flow and good capillary action to accentuate recessed details without obscuring raised surfaces. It is water-based for easy thinning and cleanup, dries to a stable finish, and blends well with other water-based paints and weathering products. The brown tone is calibrated to produce realistic mud effects for military models, vehicles and natural terrain elements in dioramas.

Suitable for

• Scale model military vehicles and armor
• Miniatures and figures requiring mud or grime effects
• Diorama terrain such as roads, fields, marshes and forest floors
• Panel lines, crevices and recessed details on plastic and resin models

Key specifications

• Finish: matte, designed to simulate natural mud and dirt
• Color: brown mud tone suitable for temperate and continental soils
• Base: water-based acrylic formulation compatible with acrylic paints and washes
• Behavior: flows into recesses and panel lines; blends when reactivated with water
• Application: brush-applied wash for fine control of coverage

How to use

Apply the wash sparingly with a fine brush along panel lines, joints and recessed details, allowing capillary action to carry the product into crevices. Remove excess with a damp brush or sponge before the wash dries to control intensity and create natural transitions. For terrain and larger surfaces, thin the wash with a little water to extend coverage and build up layers gradually, letting each layer dry before adding the next.

Usage recommendations

Test the wash on a spare part or hidden area before application to ensure the desired effect and compatibility with existing paint layers. Use in a well-ventilated area and store the container upright and tightly closed to preserve consistency.
