Why Mr Colour Levelling Thinner Is Necessary

From my experience, Mr Colour Levelling Thinner is an essential part of achieving a flawless finish when airbrushing. I’ve found that it helps paint flow smoothly through the airbrush without clogging, which is crucial for maintaining consistent spray patterns. Without it, my paint would often come out uneven or blotchy, making my work look less professional.

Another reason I rely on this thinner is how it improves the paint’s leveling properties. It reduces brush marks and surface imperfections by allowing the paint to settle evenly as it dries. This means less time spent sanding or fixing mistakes later on. For me, that smooth, even coat makes a huge difference in the final look of my models or artwork.

Lastly, Mr Colour Levelling Thinner is great for controlling drying times. It slows down the drying process just enough to give me better control over blending and layering colors. This has helped me create more subtle gradients and depth in my work, which is something I really value. Overall, I can’t imagine airbrushing without it.

My Buying Guides on Mr Colour Levelling Thinner

When it comes to achieving smooth and flawless paint finishes, especially with Mr Colour paints, I’ve found that using the right thinner is just as important as the paint itself. That’s where Mr Colour Levelling Thinner comes into play. Here’s my personal guide to help you understand why this thinner might be the perfect choice for your modeling or painting projects.

What Is Mr Colour Levelling Thinner?

Mr Colour Levelling Thinner is a specially formulated solvent designed to thin Mr Colour paints while enhancing their flow and leveling properties. Unlike regular thinners, it helps reduce brush strokes and surface imperfections, giving your painted models or surfaces a smooth, professional finish.

Why I Prefer Mr Colour Levelling Thinner

From my experience, this thinner doesn’t just dilute the paint—it actively improves the paint’s ability to self-level. When I use it, I notice fewer brush marks and a more even coating, which is essential for scale models, miniatures, or any detailed paintwork. It also dries cleanly without affecting the paint’s color or gloss.

Key Features to Consider

  • Compatibility: It works best with Mr Colour lacquer paints but can also be used with other lacquer-based paints.
  • Levelling Effect: Helps paint settle evenly, reducing the need for extensive sanding or additional coats.
  • Drying Time: Speeds up drying without causing cracking or wrinkling.
  • Volume Options: Available in various sizes, so you can choose what fits your project needs.

How I Use Mr Colour Levelling Thinner

I usually mix it with Mr Colour paint in a ratio recommended on the bottle, often around 1:1 or 1:2 thinner to paint depending on the effect I want. For airbrushing, I thin more to achieve a smooth spray pattern. For brush painting, I use a bit less to maintain good coverage. It’s great for both techniques.

Things to Keep in Mind Before Buying

  • Ventilation: Always use it in a well-ventilated area due to its strong solvent fumes.
  • Storage: Keep the container tightly closed to prevent evaporation and contamination.
  • Surface Compatibility: Test on a small area first if you’re using it on non-plastic surfaces to avoid damage.

Where to Buy and Pricing

I usually find Mr Colour Levelling Thinner at hobby stores, online retailers, or specialized paint shops. Prices are reasonable for the quality, and buying in larger bottles can save money if you paint frequently.

Final Thoughts

If you’re serious about getting that smooth, professional finish with Mr Colour paints, I highly recommend giving the Levelling Thinner a try. It’s a simple addition to your painting supplies that can make a noticeable difference in your projects’ final look. From my experience, it’s definitely worth the investment.
