Mixing paint in parts involves precisely measuring and combining different components based on a specified ratio, often provided by the manufacturer. This ensures the paint performs as intended.
To mix paint using a parts system, follow these steps:
-
Identify the Mixing Ratio: The manufacturer's technical data sheet will specify the ratio, for example, 4:1:10%. This means 4 parts paint, 1 part hardener, and 10% thinner (of the total paint + hardener volume).
-
Understand the Ratio: The numbers represent proportions, not specific units. You can use any unit of measurement (e.g., ounces, milliliters, cups) as long as you're consistent throughout the mixing process.
-
Measure Accurately: Use measuring cups, graduated cylinders, or a scale to ensure accurate proportions. Inaccurate measurements can affect the paint's color, durability, and finish.
-
Combine the Components: Pour the paint, hardener, and thinner into a clean mixing container in the correct order (usually paint first).
-
Mix Thoroughly: Stir the mixture thoroughly until all components are fully incorporated. Follow the manufacturer's recommendations for mixing time. Avoid introducing air bubbles during mixing.

Example:
Let's say you need to mix 100 ml of paint based on the 4:1:10% ratio:- Paint: (4 / 5) * 100 ml = 80 ml
- Hardener: (1 / 5) * 100 ml = 20 ml
- Thinner: 10% of the total mixture (paint + hardener). The total volume before thinner is 80 ml + 20 ml = 100 ml. Therefore thinner = 10% * 100 ml = 10 ml.
So, you would mix 80 ml of paint, 20 ml of hardener, and 10 ml of thinner.
-
Strain the Paint (Optional): If necessary, strain the mixed paint through a fine-mesh filter to remove any impurities or lumps.
-
Use Promptly: Many mixed paints have a limited "pot life," meaning they must be used within a certain timeframe after mixing. Refer to the manufacturer's instructions for pot life information.
By following these steps and the manufacturer's instructions, you can accurately mix paint in parts for optimal results.
