Mixing Cement with Pratliperl

In order to achieve an homogeneous mix, Cement must be mixed into the Pratliperl in a “dry state”. What this means is that before adding any water to the mix, one must mix the Pratliperl and Cement together until the entire mix is light grey in colour. Remember that mixing the correct ratio of Cement to Pratliperl is imperative. These ratios may be found on the back of every bag. Ratios are all Volume based which means that a 3:1 ratio means that three wheelbarrows of Pratliperl must be mixed with one Wheelbarrow of Cement. It does not mean that 3 bags of Pratliperl must be added to 1 bag of Cement.
