Mr. Color flat paints are a staple for many modelers, prized for their smooth finish and durability. However, these paints can be finicky, especially when it comes to clogging and separation. Whether you're airbrushing a detailed Gundam kit or painting Warhammer miniatures, proper care is essential to keep your paints flowing smoothly and your finishes flawless.

In this guide, we'll walk you through the best practices for storing, mixing, and maintaining Mr. Color flat paints. We'll also cover common issues like pigment separation and airbrush clogging, and how to solve them. By the end, you'll be able to keep your paints in top condition for every project.

Understanding Mr. Color Flat Paints

Mr. Color flat paints, such as the popular C70 Flat Dark Green, are solvent-based lacquer paints known for their even, matte finish. They are excellent for creating realistic military models, mecha, and dioramas. However, their composition makes them prone to separation if not handled correctly. The pigments and binders can settle over time, leading to inconsistent color and clogged airbrushes.

One of the key differences between flat and gloss paints is the addition of matting agents. These microscopic particles can clump together, especially when the paint is old or exposed to temperature fluctuations. Understanding this helps you take the right preventive measures.

  • Always shake Mr. Color flat paints thoroughly before use, even if they appear well-mixed.
  • Store paints upright in a cool, dark place to minimize pigment settling.
  • Check the consistency; if it's too thick, thin it with Mr. Color Thinner.

Preventing Pigment Separation

Pigment separation is a common issue with flat paints. You might notice a clear layer of solvent on top and a thick sludge at the bottom. This happens because the matting agents and pigments have different densities. To prevent this, make it a habit to shake your paint bottles regularly, even when not in use. A paint shaker or a small ball bearing inside the bottle can help break up clumps.

If your paint has already separated, don't panic. Add a few drops of Mr. Color Thinner and shake vigorously. For stubborn cases, use a stirring rod to mix the paint from the bottom. Avoid using water, as it can ruin the paint's chemical balance.

  • Use a dedicated paint shaker for consistent results.
  • Add a stainless steel ball to the bottle to aid mixing.
  • If separation persists, consider decanting the paint into a new bottle.

Airbrush Care: Avoiding Clogs

Clogging is the bane of every airbrush user. Flat paints are more prone to clogging than gloss or metallic paints due to the matting agents. To minimize clogs, always thin your paint properly. A ratio of 1:1 paint to thinner is a good starting point, but adjust based on your airbrush and environmental conditions.

Clean your airbrush thoroughly after each session. Run thinner through the cup and nozzle, and disassemble the needle and nozzle for a deep clean if needed. Using a cleaning station or pot can make this easier. Regular maintenance prevents dried paint from building up and causing blockages.

  • Always strain your paint before pouring it into the airbrush cup.
  • Use a moisture trap to prevent water in the air line.
  • Keep spare needles and nozzles on hand for quick replacements.

Storage Tips for Longevity

Proper storage is key to extending the life of your Mr. Color flat paints. Keep them away from direct sunlight and extreme temperatures. A consistent room temperature between 15-25°C (59-77°F) is ideal. Fluctuations can cause condensation inside the bottle, leading to separation and spoilage.

Make sure the lids are tightly sealed after each use. Solvent evaporation can thicken the paint and alter its properties. If you notice the paint becoming too thick, add a few drops of Mr. Color Thinner to restore the consistency.

  • Store bottles upside down to create a better seal and reduce skinning.
  • Label your bottles with purchase dates to track freshness.
  • Consider using a dedicated paint organizer to keep bottles upright and stable.

Maintaining Your Brushes and Tools

While this guide focuses on flat paints, your brushes and tools also need care. After using Mr. Color paints, clean your brushes immediately with the appropriate thinner. For example, the Citadel Artificer Layer Brush X-small is perfect for fine details, but it requires gentle cleaning to maintain its tip.

If you're working with multiple paint types, keep separate brushes for lacquer and acrylic paints to avoid cross-contamination. A brush cleaner or conditioner can help preserve the bristles.

  • Use a gentle brush cleaner to remove paint residue without damaging bristles.
  • Store brushes horizontally or with the tip down to prevent bending.
  • Never leave brushes soaking in thinner for extended periods.

By following these care tips, you can ensure your Mr. Color flat paints remain reliable and produce beautiful, consistent finishes. Remember, a little maintenance goes a long way in protecting your investment.
