Powdered material, based on inorganic loads, used to treat the joints where plasterboards in Pladur® plasterboard systems meet each other, and subsequent plastering with a fine layer (average thickness of between 1 and 1.5 mm), to create a flat and consistent surface, thus reducing the risk of blemishes and shadows appearing, with a Q4 finish level, as per the finish classification levels published by Eurogypsum. Contains the proper additives required for mixing with water prior to use in the work. This is a setting compound and therefore has a predefined operating time.
