BASF has developed the MasterKure 111WB, a highly effective, non-solvent-based, sprayable evaporation inhibitor, which helps to protect concrete against drying cracks in hot temperatures during the summer months. It is designed for use during the intermediate curing stage of industrial flooring concrete. The product takes effect a step earlier than conventional curing compounds (generally these can only be applied onto the matt-dry concrete surface around five hours after placing).
MasterKure 111WB prevents the water film created when the concrete has initially settled after placement from evaporating. The product forms a barrier of active-component molecules, which inhibits the evaporation of the water film. The use of MasterKure 111WB results in an 80% reduction of water evaporation during the first four hours, compared to untreated concrete, largely preventing the occurrence of early-age shrinkage cracks.
Furthermore, the thin layer of MasterKure 111WB on the surface works well as a troweling aid. When the concrete is treated with the power trowel at a later stage, MasterKure 111WB acts as a lubricant, thereby facilitating the entire troweling process.
