Yes, you absolutely can prime models with a brush.
Priming models with a brush is a common and effective method for hobbyists. Unlike priming with a spray can or airbrush, using a brush gives you more control over the application, especially for small details or when working in areas where ventilation is limited.
How to Prime Models Using a Brush
As the provided reference explains, priming with a brush is quite straightforward. Many primers designed for airbrushes are versatile enough to be applied with a brush as well. This is why some manufacturers, like Vallejo, label their products as "surface primer" rather than specifically "airbrush primer," indicating their suitability for multiple application methods.
Here are some common types of primers you can use with a brush:
- Airbrush Primers: As mentioned in the reference, pretty much every airbrush primer can also be applied via brush. These primers are often thin enough to flow well from a brush and self-level to reduce brush strokes.
- Purpose-Made Brush-On Primers: Several brands offer primers specifically formulated for brush application. The reference highlights Army Painter's Brush-On Primer as an example of a product designed for this method.
- Gesso: A product commonly found in craft and hobby stores, gesso is also a viable option for brush priming, especially on certain materials.
Tips for Brush Priming
- Thinning: While some brush-on primers are ready to use, others (especially thinned airbrush primers) might need minimal thinning to achieve a smooth consistency that reduces brush strokes.
- Multiple Thin Coats: Apply primer in thin layers rather than one thick coat. This helps preserve detail on the model and prevents the primer from obscuring fine sculpted lines. Allow each coat to dry completely before applying the next.
- Brush Choice: Use a synthetic brush that holds paint well and has a relatively soft bristle. Avoid overloading the brush with primer.
Using a brush to prime offers flexibility and control, making it an excellent option whether you're working on a single miniature or don't have access to spray or airbrush equipment.
