How much material do I need for 80 m²?

For 80 m² it is better to prepare an individual material list based on the substrate and type of surface.

Detailed answer

The most accurate approach is to base calculations on the complete system per m², rather than calculating individual products in isolation. For each surface, the substrate, number of layers, type of final coating, gel, varnish, and allowance are all considered. For bathrooms and floors, it is safer to use a ready-made set or have the system checked.

Common mistakes

  • Calculating materials without allowance
  • neglecting substrate preparation and tools
  • comparing prices without the same layer system
