Pakol Remontny Zima 400 K — antifreeze R3 mortar for non-structural repair
Coarse-grained R3 mix with an antifreeze admixture for non-structural repair of walls, columns and ceilings down to −10 °C without heating.

The non-shrink thixotropic mix with polymer fibre is designed for structural repair of overhead, inclined and vertical surfaces of concrete, brick and stone: the damage is filled in a single application. The material is used on bridges and overpasses, in tunnels and metro, tanks and treatment plants, on columns and beams; work is carried out at temperatures from +5 °C. Versions with 1.0 and 3.0 mm aggregate are available; after 28 days 40.0 MPa in compression (B30), W12, F1 300, class R3.
