BIRSS 34N — cement self-levelling floor M250

Other floor materials

This self-levelling mix of Portland cement and graded sand serves as a base for floor coverings or as a standalone finished floor. The manufacturer classes 34N among compounds for significant loads: 28-day compressive strength corresponds to class B20 (25.0 MPa), adhesion is at least 1.0 MPa, abrasion G1. The mix is poured in strips, indoors only, over BIRSS Grunt P primer; the floor can be walked on after 8 h.
