How much resin will I need?

For solid surfaces, it's easy to calculate the amount of resin you’ll need to cover a given area. For uneven surfaces or those including embedments like pennies, crushed glass or bottle tops; some compensation will be required.

1kg = 1mm over 1sqm

You will require 1 kg of resin per millimetre of thickness required over a 1 sqm area. Therefore, to calculate how much resin to mix, simply multiply the thickness you require (in millimetres) by the area of your surface (in square metres). Don't forget that porous (absorbent) materials like wood should be sealed before the main pour. Typically for a grouted penny floor we would recommend 2mm thickness over the pennies which equates to 2kg per square meter. Other projects the depth may vary.

Use the table below as a quick guide to how much resin you would need to cover different areas at a range of thicknesses:

  Surface Area to Cover
Thickness 25cm x 25cm
50cm x 50cm
50cm x 100cm
100cm x 100cm
200cm x 100cm
1mm 62.5g 250g 500g 1kg 2kg
2mm 125g 500g 1kg 2kg 4kg
3mm 188g 750g 1.5kg 3kg 6kg
4mm 250g 1kg 2kg 4kg 8kg
5mm 313g 1.25kg 2.5kg 5kg 10kg
