Mr. Color paints are a favorite among modelers for their smooth finish and wide color range. But even the best paints can degrade if not stored and maintained properly. Whether you're a seasoned hobbyist or just starting, understanding how to care for your Mr. Color paints will save you money and frustration in the long run.

In this guide, we'll cover the best practices for storing model paint, how to extend the shelf life of your Mr. Color bottles, and simple maintenance routines to keep your paints ready for your next project. From temperature control to proper sealing, these tips will ensure your paints stay fresh and vibrant.

Why Proper Storage Matters for Mr. Color Paints

Mr. Color paints are solvent-based acrylics, which means they are more susceptible to evaporation and contamination than water-based paints. If you leave a bottle unsealed or store it in a hot, sunny spot, the solvent can evaporate, leaving behind a thick, unusable sludge. Proper storage not only prevents this but also maintains the paint's consistency and color accuracy.

Additionally, temperature fluctuations can cause the paint to separate or form lumps. By controlling your storage environment, you can extend the life of your paints significantly, saving you money and ensuring your colors match every time you paint.

  • Store paints in a cool, dark place away from direct sunlight.
  • Keep the temperature consistent, ideally between 15-25°C (59-77°F).
  • Avoid storing paints near heaters, radiators, or windows.

Best Practices for Storing Model Paint

The golden rule of paint storage is to keep the lids tightly sealed. Before storing, wipe the rim of the bottle and the inside of the cap to remove any dried paint that could prevent a tight seal. This simple step prevents air from entering and solvent from escaping.

Another key practice is to store bottles upright. This minimizes the surface area of paint exposed to air in the bottle, reducing evaporation. If you have a large collection, consider investing in a dedicated paint rack or drawer to keep everything organized and upright.

For long-term storage, you might also consider transferring paints to smaller bottles as you use them. Less air in the bottle means less oxidation and slower thickening. This is especially useful for colors you use frequently.

  • Always replace the cap immediately after use.
  • Use a toothpick or a small brush to clean the cap threads before closing.
  • Consider using a paint organizer to keep bottles upright and accessible.

Extending the Shelf Life of Your Paints

Even with perfect storage, paints can eventually dry out or separate. To extend the shelf life of your Mr. Color paints, you can add a few drops of Mr. Color Thinner (sold separately) to restore the consistency. However, be careful not to over-thin the paint, as this can affect its opacity and coverage.

Another pro tip is to use a paint shaker to thoroughly mix the paint before each use. This reincorporates any separated pigments and binders, ensuring a consistent color. If you notice a skin forming on top of the paint, carefully remove it with a toothpick before stirring.

  • Add thinner drop by drop until you reach the desired consistency.
  • Shake the bottle for at least 30 seconds before each use.
  • Avoid introducing water or other solvents into the bottle.

Common Mistakes to Avoid in Paint Maintenance

One of the most common mistakes is leaving brushes in paint jars or dipping a dirty brush directly into the bottle. This contaminates the paint with dried acrylic and other debris, which can ruin the paint's finish. Instead, pour a small amount of paint into a palette or use a dropper to transfer it.

Another mistake is storing paints in the refrigerator or freezer. While this might slow evaporation, it can cause the paint to thicken or separate irreversibly due to temperature shock. Stick to a stable room temperature for best results.

Finally, don't ignore the paint's smell. If you notice a strong, unusual odor, it might be a sign of contamination or chemical breakdown. In such cases, it's safer to discard the paint and replace it.

  • Never put brushes directly into the bottle.
  • Use a palette or mixing cup for each painting session.
  • If in doubt about the paint's condition, test it on a scrap piece first.

Tools and Accessories to Simplify Paint Care

Investing in a few simple tools can make paint care much easier. A dedicated paint shaker, for instance, saves time and ensures a thorough mix. Similarly, a set of small funnels or droppers can help you transfer paints without spilling.

For those who enjoy building and painting models, accessories like the Trial Nanoblock NBH 193 - BIG BEN can be a fun way to relax between projects, but they don't directly help with paint care. However, keeping your workspace organized with storage racks and labeling systems is essential.
