Use the specified volume or weight ratio for the exact resin and hardener. Equal volumes do not necessarily have equal weights.

Epoxy Mixing Ratio Calculator: Resin & Hardener
Split a total mixture into resin and hardener using product-specific volume or weight ratios. Unknown ratios are never guessed.

A is resin; B is hardener. This splits a total mixture. It does not convert weight to volume or calculate how much hardener to add to resin already measured.
1 : 1 by volume
150 ml A
+ 150 ml B
Use the ratio for your exact formula and kit revision. Never change the ratio to speed up curing.

Check batch limits before measuring
The calculator splits the amount you enter; it does not establish that the entire amount can be safely mixed in one container.
Check handling and batch conditions →Keep the recipe with the project
Record the formula revision, measurement method and actual amounts alongside room conditions so a later observation has useful context.
