1. Product Overview
This manual provides detailed instructions for the proper use and maintenance of Tamiya Acrylic Model Paint, specifically the XF-65 Field Gray color. Tamiya acrylic paints are formulated with water-soluble acrylic resins, making them versatile for both brush and airbrush applications. They adhere well to various surfaces including styrene resins, Styrofoam, wood, and common model plastics. The paint offers good coverage, smooth flow, and is easy to blend. Before it fully cures, the paint can be cleaned with plain water.

2. Safety Information

- Ventilation: Use in a well-ventilated area to avoid inhaling paint fumes. If working indoors, ensure adequate airflow or use a respirator.
- Skin and Eye Contact: Avoid direct contact with skin and eyes. In case of contact, rinse immediately with plenty of water. If irritation persists, seek medical attention.
- Ingestion: Do not ingest. If swallowed, do not induce vomiting. Seek immediate medical attention.
- Children: Keep out of reach of children and pets. This product is not a toy.

3. Product Components
The product package contains:
- One (1) bottle of Tamiya Acrylic Paint XF-65 Field Gray (75 Milliliters).
4. Setup and Preparation
Proper preparation ensures optimal paint performance and finish.
- Shake Well: Before each use, thoroughly shake the paint bottle to ensure pigments are evenly mixed.
- Surface Preparation: Ensure the model surface is clean, dry, and free of dust, grease, or mold lines. Priming the surface is recommended for best adhesion and color vibrancy.
- Thinning for Airbrushing:
- For standard airbrushing, use Tamiya X-20A Acrylic Thinner. Follow the thinner manufacturer's recommendations for mixing ratios, typically 1 part paint to 1-2 parts thinner, adjusting as needed for desired consistency and airbrush performance.
- For a faster drying time and a harder finish, Tamiya Lacquer Thinner can be used as an alternative for airbrushing. Exercise caution and ensure proper ventilation when using lacquer thinner.
- Enhancing Brushing Results: To achieve a smoother, stroke-free finish when brush painting, consider adding Tamiya Paint Retarder (87114). Add a small amount (e.g., 1-2 drops per 10ml of paint) and mix thoroughly.
5. Operating Instructions (Application)
5.1. Brush Application
- Apply paint in thin, even coats. Avoid applying thick layers, as this can lead to uneven drying and loss of detail.
- Allow each coat to dry completely before applying the next. This typically takes 10-20 minutes, depending on humidity and temperature.
- For best results, use a high-quality brush appropriate for model painting.
5.2. Airbrush Application
- Ensure the paint is thinned to the correct consistency for your airbrush. A milk-like consistency is often a good starting point.
- Maintain a consistent air pressure, typically between 15-25 PSI, adjusting as needed for desired spray pattern and paint flow.
- Apply paint in light, even passes. Over-spraying can lead to pooling or runs.
- Allow flash-drying between coats to prevent paint build-up and ensure a smooth finish.
5.3. Drying and Curing
- Tamiya acrylic paints are touch-dry within minutes. However, allow several hours for the paint to fully cure and harden before handling extensively or applying subsequent layers like clear coats or washes.
- The XF series paints, including XF-65 Field Gray, provide a flat (matte) finish.
6. Maintenance and Cleaning
Proper cleaning extends the life of your tools and ensures consistent results.
- Brushes: Immediately after use, clean brushes with plain water before the paint dries. For dried paint, use Tamiya X-20A Acrylic Thinner or a dedicated brush cleaner.
- Airbrush: Flush the airbrush with water immediately after painting. For thorough cleaning, especially after using lacquer thinner, disassemble and clean components with the appropriate thinner or airbrush cleaner.
- Storage: Always securely cap the paint bottle after use to prevent drying and contamination. Store in a cool, dry place away from direct sunlight and extreme temperatures.
7. Troubleshooting
- Paint is too thick/clogging: Add a small amount of Tamiya X-20A Acrylic Thinner (or Lacquer Thinner for airbrushing) and mix thoroughly until desired consistency is achieved.
- Poor coverage/transparency: Ensure the paint is well-mixed. Apply additional thin coats, allowing each to dry completely. Consider priming the surface.
- Visible brush strokes: Ensure paint is not too thick. Add Tamiya Paint Retarder (87114) to slow drying and allow paint to self-level. Use a high-quality brush.
- Paint peeling/poor adhesion: Ensure the surface is clean, dry, and properly prepared. Priming may be necessary for certain materials.
