Frequently Asked Questions
An epoxy calculator helps you estimate the amount of epoxy resin and hardener required for a project based on surface area and thickness.
It provides a theoretical estimate. Actual usage may vary due to waste, surface texture, and mixing precision. Always buy a little extra.
It assumes a 1:1 ratio by volume of resin to hardener. Adjust if your epoxy uses a different ratio.
