Usage Instructions
1. Thinning TAMIYA Acrylic Paints
For optimal results, especially when airbrushing, TAMIYA X-20A Acrylic Thinner should be used to achieve the desired paint consistency. The ideal thinning ratio can vary depending on the specific paint color, application method (brush or airbrush), and desired finish. Start with a small amount of thinner and gradually add more until the paint flows smoothly.
Airbrushing:
- Mix TAMIYA acrylic paint with X-20A thinner in a separate mixing cup.
- A common starting ratio is 1 part paint to 1-2 parts thinner, but this may need adjustment.
- Stir thoroughly until the mixture is uniform and free of lumps.
- Test the consistency on a scrap piece before applying to your model. The paint should spray smoothly without clogging or sputtering.
Brush Painting:
- Add a small amount of X-20A thinner to your paint on a palette.
- Mix until the paint has a smooth, flowing consistency, similar to milk.
- Avoid over-thinning, as this can reduce paint opacity and coverage.
2. Cleaning Painting Tools
TAMIYA X-20A Acrylic Thinner is highly effective for cleaning TAMIYA acrylic paints from brushes, airbrushes, and other tools.
Cleaning Brushes:
- Immediately after use, rinse brushes thoroughly with X-20A thinner.
- Gently work the thinner into the bristles to remove all paint residue.
- For dried paint, soak the brush in a small amount of X-20A thinner for a short period, then clean as usual.
- Rinse with water and reshape the bristles before storing.
Cleaning Airbrushes:
- Empty any remaining paint from the airbrush cup.
- Pour a small amount of X-20A thinner into the cup and spray it through the airbrush until clear.
- Repeat as necessary.
- For thorough cleaning, disassemble the airbrush and clean individual components with thinner and appropriate cleaning tools.

Troubleshooting
Paint not thinning properly:
- Ensure you are using TAMIYA X-20A Acrylic Thinner specifically for TAMIYA acrylic paints. Other thinners may not be compatible.
- Check the paint's age; very old or dried paint may be difficult to thin.
- Gradually add thinner and mix thoroughly. Over-thinning can also cause issues.
Airbrush clogging:
- Ensure paint is adequately thinned and mixed without lumps.
- Clean your airbrush thoroughly before and after each use with X-20A thinner.
- Check for dried paint in the nozzle or needle assembly.
Brushes not cleaning effectively:
- Clean brushes immediately after use.
- For stubborn dried paint, soak brushes in X-20A thinner for a longer period (e.g., 15-30 minutes), then agitate and rinse.
- Avoid letting paint dry completely on brushes.
Maintenance
- Store the TAMIYA X-20A Acrylic Thinner in a cool, dry, well-ventilated place, away from direct sunlight and sources of ignition.
