Mixing ratio calculator

How many litres of each component make the mixed volume you need, from the ratio by volume on the data sheet.

Mixed volume needed (L) Ratio by volume (e.g. 3:1 or 3 1) Thinner (% of mixed paint)

This tool is a reference aid. Before you act on a result, check it against your specification and the product data sheet.

Worked example

A 3:1 ratio is 3 parts base and 1 part hardener: 4 parts in total. For 8 L, base = 8 × 3 ÷ 4 = 6 L and hardener = 2 L. The trap is a hardener of one third of the mix (2.7 L).

Good practice

Mix full kits where you can; split kits only by measured volume.
If the data sheet gives the ratio by weight, weigh the components.
Pot life starts when the components meet; induction time, if any, comes before application.

Try it in an exam-style question. The published AMPP CIP Level 1 guide lists mixing, induction time and pot life, and the FROSIO book lists them among the data-sheet items. The free readiness check shows the question style and explains every answer.
