Composition
Portland cement M-500 with mineral fillers and a complex of modified additives.
Application
The Master “Stiazhka” mixture is intended for the equipment of floor screeds on rigid bases with a layer thickness of 15 to 80 mm. Such a mixture can be laid on hydro-, heat- and sound-insulating surfaces, the thickness is determined depending on the rigidity of the heat- and sound-insulating material and the intensity of the impact on them of mechanical loads (the minimum layer must be at least 40 mm). The mixture is also used for leveling and repairing concrete and cement-sand screeds. The technological properties of the mortar mixture allow you to prepare the surface for laying finishing tiles, carpet, linoleum or paint without applying a self-leveling mixture. A self-leveling mixture, Master “Nivelir Finish”, can be laid on the Master ” Stiazhka ” layer.
