What is the consumption of Primer Plus per m²?

The consumption of Primer Plus varies depending on the absorbency of the substrate. Absorbent surfaces will take significantly more product than tiles or other non-absorbent substrates. As a general guide, for absorbent surfaces expect approximately 1 kg per 5–7 m², while for non-absorbent surfaces about 1 kg per 15 m². For challenging substrates, it is advisable to allow a small reserve. Consumption: Absorbent surfaces – approx. 1 kg / 5 - 7 m² (depending on absorbency level). Consumption for non-absorbent surfaces – approx. 1 kg / 15 m².
