Resin Calculator FAQs

A 2:1 ratio means you mix 2 parts resin with 1 part hardener. For example, if the total mixture required is 300 g, the calculator divides it according to the selected 2:1 ratio.
A 3:1 ratio means you mix 3 parts resin with 1 part hardener. Always check the instructions on your particular resin product before mixing.
We recommend allowing a small amount of extra material because some resin can remain inside mixing cups, measuring containers and tools. The calculator gives you 0%, 5%, 10% and 15% options.
Yes. For coating calculations, enter the surface dimensions and choose the coating thickness. If you are using a specific resin, always compare the calculator result with the manufacturer's recommended coverage rate.
The result is an estimate based on the dimensions you enter and the density setting used by this calculator. Actual resin usage may vary because of mould geometry, embedded objects, surface irregularities and application losses.
