Urgent repair of shallow spalls, gouges and cavities in autumn and spring is carried out with this fine-grained thixotropic mix with 1.0 mm aggregate and polymer fibre. It is applied at temperatures from −10 to +7 °C to vertical, inclined and overhead surfaces of bridges, tunnels, dams, tanks, columns and beams. After 2 h: 10.0 MPa, after 28 days: 50.0 MPa in compression (M500), W14, F1 500, class R4.
