Profskrin RC45, a thixotropic repair mortar of class R4, is designed for structures made of B30–B40 concrete. It is applied by hand or by machine and holds on vertical and overhead surfaces, so it suits the restoration of columns, beams and soffit areas of industrial buildings. Compressive strength is at least 20 MPa after 24 hours and 45 MPa after 28 days, bond to the substrate from 2 MPa, water impermeability W16, frost resistance F1 1000.
