Mortar 456 is intended for making a basic, profiling repair layer in the concrete repair system at KREISEL. Mortar 456 can be the final finishing layer at elements that do not require perfect surface smoothness or it can be a primer for mortar 460. It is characterized by low shrinkage, high adhesion and rapid increase in mechanical strength. For use in the 5-50mm layer. The system allows the repair of an element in concrete and reinforced concrete damaged under the influence of a factor in mechanical, physical and chemical (causing destruction of concrete and corrosion of steel). It is suitable for repairing such elements as: balconies, terraces, brackets, columns, lintels, etc. It can also be used for local repair and removal of defects in the concrete surface (e.g. defects, cancer, caverns). This mortar is water and frost resistant.
