This information is to assist with calculating the amount of mortar required for bedding, bonding and grouting.

The calculation for bedding mortar is straightforward and may be assessed on the basis of a conversion factor of 1.8 (if not applying a factor for waste) or 2.0 (if allowing nominal 10% waste).
Using a Conversion Factor of 1.8 - 2.0 the following simple rule can be applied:
30 mm deep bedding requires 56 - 60 kg / m²
40 mm deep bedding requires 72 - 80 kg / m²
other depths pro rata.
A useful method, if assuming 10% waste, is to multiply the depth of the bedding mortar in millimetres by 2, to arrive at the consumption in kg/m²
