Ceresit CT 73 is used for making thin-layer plasters on concrete substrates, traditional plasters, gypsum substrates and chipboards, gypsum cardboards, etc. We recommend the application of the plaster CT 73 as façade plaster within Ceresit ETICS (External Thermal Insulation Composite Systems) with the application of EPS-boards (Expanded Polystyrene boards) and mineral wool. CT 73 plaster is recommended to be applied on the partitions where high permeability is required. CT 73 is available in a wide range of colours, but in case of intensive dark colours, the material application on the façades should be limited to small areas, e.g. architectural details. Plaster CT 73 is protected form biological paralyses, e.g. fungus, mould and algae.
