Preparation
- Ensure a Clean Surface: Before application, ensure the model surface is clean, dry, and free from dust, grease, or other contaminants.
- Stir the Paste: Gently stir the weathering paste in its container to ensure a consistent texture and color.
- Dilution (Optional): For thinner applications or different effects, the paste can be diluted with the dedicated Mr. Weathering Color Thinner (WCT101), sold separately. Start with small amounts of thinner and mix thoroughly until the desired consistency is achieved. Do not use other types of thinners unless specified, as they may react negatively with the paste.
Application Instructions
Apply the weathering paste using a brush, spatula, or other suitable modeling tools. The application method will depend on the desired effect.
- For Heavy Mud Stains: Apply the paste directly to the desired areas, building up layers to create depth and texture. Use a brush or spatula to sculpt the mud into realistic shapes.
- For Splatter Effects: Load a stiff brush with diluted paste and flick it onto the model for realistic mud splatters.
- For Dirt Accumulation: Apply a thin layer of paste and then use a dry brush or cotton swab to remove excess, leaving dirt in recesses and around details.
- Layering: This paste can be layered over other weathering products or paints once they are dry.
Drying
The drying time for the weathering paste can vary depending on the thickness of the application, humidity, and temperature. Allow sufficient time for the paste to fully cure before handling or applying additional layers. Thicker applications will require longer drying times.
Maintenance and Cleaning
Clean brushes and tools immediately after use with Mr. Weathering Color Thinner (WCT101) or a suitable acrylic cleaner. Ensure the paste container is tightly sealed after each use to prevent drying out.
Troubleshooting
- Paste is too thick: Dilute with Mr. Weathering Color Thinner (WCT101) in small increments until desired consistency is reached.
- Paste not adhering: Ensure the surface is clean and dry. A primer layer may improve adhesion on some materials.
- Uneven application: Use a consistent amount of paste and apply with even strokes. For textured effects, vary application intentionally.
