Calculate epoxy volume, resin and hardener amounts, mix ratios and waste.
Read full description
Epoxy Calculator estimates pour volume, waste allowance, and mix ratios for epoxy projects. Enter rectangle, circle, or custom-area dimensions, depth, and units. Split resin and hardener by weight or volume, estimate material cost, set a cure timer, and keep a project journal. Inputs and results remain editable and are clearly labelled as estimates. Project records stay on your device unless you choose to export or share them. Contains ads.
