Subjects: Car paint , 2K 08 January 2025

A good mixing ratio of car paint is essential for achieving a perfect finish. By correctly mixing the paint with the right component, you’ll get a professional result without issues. In this blog article, we explain exactly what a car paint mixing ratio is, how to apply it, and we give you useful tips for easily mixing car paint according to the correct ratio. This way, you can be sure your project will succeed!

What does mixing ratio actually mean?

The mixing ratio indicates how many parts of two or more components you need to combine. With car paint, it often involves a paint component and a second component, such as a hardener, thinner, or water, depending on the type of paint used.

The ratio is always based on volume, not weight. This means you measure in liters or milliliters, not in grams.

Why mixing ratios are important

Every car paint has its own mixing ratio. Correctly following this is essential to guarantee the processing properties, quality, drying time, and coverage of the paint.

An incorrect mixing ratio can cause the paint to not cure properly, become too thin, or cover unevenly. That’s why it’s important to always check the recommended ratio on the product label or in the product description at CROP.

How does a mixing ratio work in practice?

Mixing ratios are indicated as, for example, 1:4, 1:2, or even 1:10. You pronounce this as "1 to 4" or "1 to 2". This means that, for example, you add 1 part hardener to 4 parts paint.

How much is a 1:4 mixing ratio?

With a 1:4 mixing ratio, you add one part of the second component to four parts paint.

Examples of a 1:4 mixing ratio:

  • 500ml paint → 125ml hardener
  • 1 liter paint → 250ml hardener
  • 4 liters paint → 1 liter hardener

How much you need to add by volume depends on the amount of paint you use.

To mix paint correctly, it’s handy to use specific paint supplies. These ensure you can work quickly and accurately, without having to calculate yourself.
