How much material do I need for 90 m² of flooring?

The most accurate approach is to base calculations on the complete layering per m², rather than calculating individual products in isolation. For each surface, factors such as the substrate, number of layers, type of final coat, gel, varnish and contingency need to be considered. For bathrooms and floors, it is safer to use a ready-made set or have the layering checked. Choose a flooring set.
