Profskrin RC45 FLq — winter flowable R4 mortar with polymer fibre
Flowable R4 repair mortar with polymer fibre for work at −10…+10 °C on bridges, treatment plants and underground structures; 45 MPa at 28 days.

The distinguishing features of Profskrin RC470 are water impermeability W20 and frost resistance F2 400 at class R4. The mortar is intended for structural repair of high-strength concrete and reinforced concrete structures of class B50 and above and is applied by hand or by machine, including on vertical and overhead surfaces. Compressive strength is from 35 MPa after 24 hours and from 70 MPa after 28 days, flexural strength 5 and 10 MPa, bond to the substrate at least 2 MPa.
