How much TotalBoat Fathom epoxy do I need?

Calculate the cavity volume from length, width and pour depth, then add a practical waste allowance. The calculator above shows the raw volume and planned purchase quantity in Metric or Imperial units.

River tables and larger castings use different depth limits

The verified TotalBoat guidance stored by EpoxyCalc is not one generic number for every project. River tables and slab pours use a conservative 2 inch limit, while larger castings can be planned up to 3 inches under the published guidance. Temperature and total project mass still matter.

TotalBoat Fathom mix ratio

The current verified data records 2:1 by volume and 100:44 by weight. Do not switch between those measurement methods unless the current product instructions explicitly support it. For exact batch splitting, use the resin and hardener ratio calculator.

Independent, not official

This calculator is an independent planning tool. Before ordering, mixing or pouring, re-check the current TotalBoat product page and technical instructions, especially when your project is close to a published depth or temperature limit.
