Epoxy calculators

Each calculator shows its formula, its assumptions and a worked example below the tool. Calculators that use product data only use values the manufacturer publishes, and refuse to guess when a value is missing.

• River table epoxy calculator

  How much resin does this river need?

  Work out how much mixed epoxy a river table needs from river length, average width and pour thickness, with void and mixing allowances.

• Deep-pour layer planner

  How many pours, and how long between them?

  Split a thick epoxy pour into layers using the maximum pour depth and wait time published in each product's data sheet.

• Epoxy mix ratio converter (volume and weight)

  How much Part A and Part B, by cup or by scale?

  Turn a total amount of mixed epoxy into Part A and Part B amounts by volume and by weight, using only ratios and densities the manufacturer publishes.

• Tabletop flood coat coverage calculator

  How much epoxy covers this tabletop?

  Calculate how much epoxy a tabletop or bar top flood coat needs from the surface size, coat thickness, edges, number of coats and mixing loss.

• Resin mold volume calculator

  How much resin fills this mold?

  Find the volume of a rectangular, round or irregular mold, subtract embedded objects, and get the amount of mixed resin to prepare.

• Epoxy cost estimator

  What will the resin cost?

  Estimate what a pour costs from the resin you need, the package size you can buy and the price you pay. No prices are stored on the site.

• Epoxy pour temperature and timing helper

  Is my shop warm enough, and when is each stage?

  Compare your shop temperature with a product's published range and turn its pot life, recoat and cure times into clock times.

• Epoxy batch splitter

  How do I mix 5 gallons with a 2 gallon bucket?

  Split a large epoxy pour into equal batches that fit your bucket, with Part A and Part B amounts for each batch.
