There are several ways to matte acrylic paint, from the application process to using specific products. Here's a breakdown of methods to achieve a matte finish:
Methods for Matting Acrylic Paint
1. Application Techniques:
- Use a large, flat brush with soft synthetic bristles: This minimizes brushstrokes and helps achieve a smoother, less glossy surface.
- Apply thin, even coats: Multiple thin coats are better than one thick coat, as they dry more evenly and reduce shine. Avoid overworking the paint, as this can increase gloss.
2. Using Additives:
- Matte Mediums: These are the most reliable way to matte acrylic paint. Mix a matte medium (like Liquitex Matte Medium or Golden Matte Medium) with your acrylic paint. Experiment with different ratios to achieve your desired level of matte. Start with a 1:1 ratio and adjust as needed.
- Matting Agents: Certain additives are specifically designed to reduce gloss. Look for products labeled as "matting agents" or "de-glossers." Always follow the manufacturer's instructions for proper mixing ratios.
- Avoid Glossy Primers: Start with a matte or neutral primer to provide a foundation that won't contribute to the final gloss level.
3. Varnish for a Matte Finish:
- Apply a Matte Varnish: After your painting is completely dry, apply a matte varnish. This will seal and protect the painting while providing a uniform matte finish. Popular brands include Krylon Matte Finish, Liquitex Matte Varnish, and Golden Matte Varnish.
- Isolation Coat (Optional but Recommended): Before varnishing, consider applying an isolation coat. This is a clear, non-removable layer (usually a diluted gloss medium) that protects the painting and ensures even varnish application.
- Applying Varnish Evenly: Use a soft brush or spray varnish in thin, even coats to avoid streaks or pooling.
4. Slow Down Drying Time:
- Use Retarders: Retarders slow down the drying time of acrylic paint, allowing for more blending and a smoother, less glossy finish. Add these sparingly, as too much can compromise the paint's integrity.
- Maintain Humidity: Keep your painting environment humid to slow down drying. You can use a humidifier or lightly mist the painting surface with water.
5. Addressing Oil Halo Issues:
- Use Fluid Matte Medium in Underpainting: If you're experiencing an "oil halo" (a slight sheen that appears when oil from the paint rises to the surface), incorporating Fluid Matte Medium in your underpainting layers can help prevent this issue.
Summary Table
| Method | Description | Pros | Cons |
|---|---|---|---|
| Matte Mediums | Mixing matte medium with paint. | Consistent results, easy to control the level of matte. | Can alter the paint's consistency slightly. |
| Matte Varnish | Applying a matte varnish as a final coat. | Provides protection and a uniform matte finish. | Can be difficult to apply evenly, may require an isolation coat. |
| Application | Using appropriate brushes and thin coats. | Simple, requires no additional materials. | Results may vary, requires careful technique. |
| Retarders | Adding retarders to slow down drying time. | Allows for better blending, reduces brushstrokes. | Can weaken the paint film if used excessively. |
| Matting Agents | Using specific de-glossing additives. | Highly effective at reducing gloss. | Requires precise measurements, can affect paint properties. |
| Starting with a Matte Primer | Priming canvas with a matte or neutral primer. | Prevents unwanted shine, helps with paint adhesion. | Requires an additional step in the painting process. |
By combining these techniques, you can effectively matte acrylic paint and achieve your desired artistic outcome.
