Paint Mix Ratio Calc helps you quickly calculate paint, hardener and thinner amounts for 2K and 3K paint mixing.

Enter a mix ratio, thinner percentage and target amount, and the app calculates each component amount. You can also calculate from the base paint amount or estimate the required amount from area and coverage rate.

Main features:
• 2K paint mix ratio calculation
• 3K paint mix ratio calculation
• Hardener and thinner amount calculation
• Calculate from total amount or base paint amount
• Coverage and required amount calculation
• Calculation history
• Mix ratio templates
• Unit switching

This app is a calculation aid. Always check the paint manufacturer's technical data sheet, product label and application instructions before actual use. Results may vary depending on product, temperature, humidity, application method and working conditions.
