The mix with an antifreeze admixture is designed for non-structural repair at low positive and negative temperatures — down to −10 °C without heating. It is coarse-grained (aggregate up to 3 mm), thixotropic, non-shrink, with polymer fibre; it is applied to vertical, inclined and overhead surfaces with spalls and gouges in industrial buildings, on columns and beams. Class R3, B30, after 28 days 40.0 MPa in compression, W14, F1 300.
