Dirty Down - Moss 25ml

The Dirty Down Weathering FX range offers a professional-grade solution for creating ultra-realistic weathering effects on your models and dioramas. Developed to replicate natural processes such as corrosion, oxidisation, and organic growth, these effect paints are trusted by hobbyists, model makers, and film studios worldwide.

Each colour is a dark liquid that dries within minutes to a convincing matt finish, producing authentic results without the need for complex layering. Ideal for use on rough or textured surfaces, the paints bring instant life and depth to vehicles, structures, and scenery.

Key Features

• Ultra-realistic finishes – simulates rusting metal, corroded copper/bronze, or moss-covered surfaces.
• Quick-drying – effects form in 1–5 minutes depending on temperature.
• Versatile application – apply straight from the pot by brush, sponge, cloth, or airbrush/sprayer.
• Adjustable intensity – build up layers for darker tones or dilute on a separate palette for lighter effects.
• Water soluble – easily tone back or remove effects with water before sealing.
• Multi-surface use – suitable for non-porous surfaces such as plastic, resin, and metal (test first on painted or sealed surfaces).
• Professional finish – can be sealed with a light mist of acrylic varnish for durability.

Usage Tips

• Always shake and stir thoroughly before use to mix pigments fully.
• For the best results, ensure the paint and surface are at room temperature or warmer.
• Avoid adding water directly into the main pot—decant if thinning is required.
• Use multiple coats, patchy applications, or water dabbing techniques to create variation in tone and texture.
• Clean brushes and tools immediately with water (or methylated spirits if dried).
