How to Applying AK Neutral Grey filter


Here’s how to apply AK Interactive’s Neutral Grey filter to your model:


  • AK Interactive Neutral Grey Filter
  • Soft, flat brush
  • Water cup (optional)
  • Cotton swabs (optional)
  • Model with a completed base coat (preferably light or white)


  1. Ensure your model is completely dry and free of dust or grease. This allows for better paint adhesion and prevents the filter from creating unwanted textures.

Applying the filter:

  1. Shake the bottle of AK Interactive Neutral Grey Filter well before use.
  2. Dip your brush lightly into the filter. A small amount is sufficient, as too much can easily overwhelm the lighter base colors and become difficult to control.
  3. Apply the filter in thin, even layers onto the desired areas of your model. Focus on areas where you want to subtly alter the base tone, like recesses, panels, or around raised details.
  4. **Work quickly and blend the filter as you apply it. You can use a damp brush (lightly dipped in water) to gently blend the filter and create smoother transitions, especially on larger areas. Be mindful not to over-wet the filter, as this can remove it entirely.

Additional Tips:

  • Start with a light touch and gradually build up the effect. It’s easier to add more filter than to remove it if you apply too much initially.
  • Use a cotton swab dipped in clean water to remove any unwanted filter stains or correct mistakes. This is most effective when the filter is still slightly wet.
  • Practice on a scrap piece of plastic or a spare model part before applying the filter to your main model. This helps you get comfortable with the consistency and application technique.
  • Allow each layer to dry completely before applying the next. This ensures better control and prevents the filter from becoming muddy or uneven.

Things to Consider:

  • The effect of the Neutral Grey filter will depend on the base color of your model. On darker base colors, the filter might have a less noticeable impact.
  • Experiment with different brushstrokes and application techniques to achieve varied effects. Stippling the filter can create a mottled texture, while gentle washes can create subtle tonal variations.
  • AK Interactive offers other filter products in various colors. You can combine them with the Neutral Grey filter to achieve even more diverse and realistic effects on your model.

By following these steps and practicing your technique, you can effectively use AK Interactive’s Neutral Grey filter to add subtle tonal variations and enhance the depth and realism of your scale models.
