Quick answer

Acrysion BN01 Base White is a versatile acrylic paint that acts as both a primer and a base coat for model kits. It covers mold colors well, enhances subsequent colors, and can be used directly on ABS and resin without a separate surfacer. It's a solid choice for light-colored or white-based paint schemes.

What makes Acrysion BN01 different from a standard primer

Most hobby primers are designed solely to create a uniform, adhesive surface for paint. Acrysion BN01 goes a step further by also functioning as a base color. This means you can prime your model and lay down a white foundation in one step, saving time and reducing paint layers. The paint covers mold color well and is formulated to enhance the vibrancy of subsequent Acrysion colors.

When to choose Acrysion BN01 over a dedicated surfacer

If your project calls for a white or light-colored finish, Acrysion BN01 is an efficient all-in-one solution. It works on ABS and resin without needing a separate surfacer, which simplifies your workflow. However, if you need heavy sanding or filling of seam lines, a dedicated surfacer (like Mr. Hobby Aqueous Surfacer 500) provides better build and sandability. Acrysion BN01 is best for clean builds where you just need a smooth, opaque white base.

Application tips for best results

Shake the bottle thoroughly before use. Thin the paint with Acrysion thinner or a compatible acrylic thinner to achieve a milky consistency. Apply in thin, even coats, allowing each layer to dry for 10-15 minutes. For full opacity on dark plastic, two to three coats may be needed. Clean your airbrush immediately after use with acrylic cleaner or isopropyl alcohol.

Decision rules for choosing Acrysion BN01

  • Project color scheme: If your final color is white, light gray, or a pastel shade, Acrysion BN01 provides an ideal base. For dark or metallic finishes, a gray or black primer may be better. Best for light-colored builds.
  • Surface preparation needs: If you need to fill scratches or sand heavily, use a dedicated surfacer first. Acrysion BN01 is not a filler. Skip for heavy surface correction.
  • Material compatibility: Works on ABS and resin without a separate primer. For polystyrene (common Gundam plastic), it adheres well but test on a sprue first. Suitable for most model kit plastics.
