A fast-setting, quick-drying, hydraulic binder based on special cement and modified polymer, after mixing with a suitable aggregate at the construction site. Used to increase the thickness of concrete and compressive layers before placing the finishing surface. Ideal material for thickening the underlay in compression, before applying a finish such as parquet, ceramics, etc.
