Approximately 1.3 kg/m2 is used for 1 mm-thick layer.
An optimum layer thickness is 2 mm, and then approx. 2.6 kg of the product per square metre is used, which means that a 25 kg bag should suffice to cover an area of 8 – 10 m2 of concrete. More product will be used when applied on surfaces of cement-lime plaster; with one bag, an area of around 6 – 8 square metres will be covered.
