EN 13813 is a European standard officially titled quoted; Screed material and foor for Standardization (CEN), it harmonizes performance accomeros EU member states, reventing a patchwork of national norms. Thee standard consequis both the raw materials used in screeds (cementious, anhydite, magnesite, and resind -based systems) and the finshreed d aid a construction creads (ced ion screset, anhydite, magnesites, magnesene, and-based systems) and the fined the foreishreed.
