What is the ratio of epoxy and hardener?

Typically, this is 1: 1 or 2: 1 between resin and hardener, but there are also much more complicated ones such as 100: 45. You can usually find the details on the packaging or containers. The mixing ratio has to be very precise, otherwise the epoxy resin will not harden or it will not work optimally.

How do you calculate how much epoxy resin to use?
