Quick answer
Warpaints Air Matt Grey Primer delivers smooth, even coverage straight from the bottle. Use thin, even coats and clean your airbrush between passes for best results.
Why grey primer works for most miniatures
Grey primer is a neutral base that works well with both light and dark topcoats. It doesn't wash out bright colors like white can, nor darken them like black. This makes it a versatile choice for a wide range of miniature painting projects.
Step-by-step application guide
- Prepare your workspace and miniatures: Ensure your miniatures are clean and free of dust or mold release. Set up your airbrush station in a well-ventilated area. Warpaints Air Primer is water-based and safe for indoor use, but always use a spray booth or mask. Skipping cleaning can cause primer to bead up or peel later.
- Load the airbrush with Warpaints Air Matt Grey Primer: Shake the bottle thoroughly. Pour a small amount into your airbrush cup. The primer is ready-to-use, so no thinning is needed. Start with a low air pressure (around 15-20 PSI). Too high pressure can cause sputtering or a rough texture.
- Apply thin, even coats: Hold the airbrush 6-8 inches from the model. Begin spraying off the model, then sweep across in smooth passes. Apply a light first coat, let it dry for 2-3 minutes, then apply a second coat for full coverage. A single heavy coat will pool and hide details. Thin coats preserve sharp edges.
- Clean the airbrush between coats: After each coat, run a small amount of water or airbrush cleaner through the nozzle to prevent tip dry. This keeps the primer flowing smoothly and avoids clogs. Dried primer in the nozzle is the most common cause of sputtering.
- Let the primer cure fully before painting: Allow the primer to dry for at least 30 minutes. For best adhesion, wait a few hours or overnight before applying base colors. The fine pigments will retain every detail, but only if the primer is fully cured. Rushing to paint can cause the primer to lift or mix with your topcoat.
