Concrete used for flooring, like any other material, can sometimes be damaged and require minor local repairs. In order to repair concrete floors, concrete repair materials are used, often also called concrete repair masses. An example of concrete repair chemicals are Ultralit polymer repair preparations, agents characterized by low viscosity, quick drying, suitable for both internal and external repairs. Also necessary when working with concrete floors are dilatation compounds, such as the one-component Ultralit Flex PU40 sealing compound, which we supplement with expansion holes.
