How Much Primer Do I Need for 80 m²?

The consumption of Primer Plus varies depending on the absorbency of the substrate. Absorbent surfaces take significantly more than tiles or other non-absorbent substrates. As a guideline, for absorbent surfaces, expect approximately 1 kg per 5–7 m², and for non-absorbent surfaces about 1 kg per 15 m². For challenging substrates, it's better to have a small reserve. Consumption: Absorbent surfaces – approximately 1 kg / 5–7 m² (depending on the degree of absorbency) Consumption Non-absorbent surfaces – approximately 1 kg / 15 m².
