BIRSS 34N — cement self-levelling floor M250
Cement finishing self-levelling floor M250 for residential, public and industrial premises; foot traffic after just 8 h.

Repair of high-strength reinforced concrete at sub-zero temperatures is carried out with BIRSS VRS 600 Moroz, which is applied in the range from −15 to +5 °C. The thixotropic mortar with fibre and compensated shrinkage restores corners of columns and beams and balcony edges destroyed by reinforcement corrosion, surface defects and working joints; it is not recommended as a pourable mortar. Even when hardening at −15 °C the compressive strength at 28 days is 55 MPa, at +20 °C 60 MPa; class R4, W16, F2 400.
