How to use this tool

  1. Enter coated area, dry film thickness, solids by volume, waste allowance.
  2. Select Calculate to view the result.
  3. Check the method and assumptions below before using the result.

The method, explained

Litres = area × dry thickness in micrometres /1000 ÷ solids fraction, with allowance.

A WORKED EXAMPLE

Using coated area = 40 m², dry film thickness = 500 µm, solids by volume = 100 %, waste allowance = 10 %, the result is 22 L. Change these example inputs to match your task; use the method above to check each step.

Understanding your result

Use the combined mixed coating’s volume solids. Substrate absorption, pot life, minimum coat thickness and mixing ratios follow the product instructions.

What to keep in mind

Use the combined mixed coating’s volume solids. Substrate absorption, pot life, minimum coat thickness and mixing ratios follow the product instructions. A material-quantity estimate, not a structural design or building-code check. Confirm site measurements, supplier coverage and waste before ordering.

Common questions

How do I use this epoxy coating quantity calculator?

Estimate coating volume for a target dry-film thickness and solids-by-volume percentage. Enter coated area in m², dry film thickness in µm, solids by volume in %, waste allowance in %. The starting example is editable; use values for the same system or project.

Which assumptions affect this result?

Use the combined mixed coating’s volume solids. Substrate absorption, pot life, minimum coat thickness and mixing ratios follow the product instructions.
