Composition
Portland cement M-500 with mineral fillers and a complex of modified additives.
Application
The easily leveling mortar mixture Master “Nivelir Start” is intended for arranging floor screeds on hard substrates with a layer thickness of 15 to 80 mm. This mixture can be laid on hydro-, heat- and sound-insulating surfaces, the thickness depends on the hardness of the heat- and sound-insulating material and the intensity of mechanical loads on them (minimum layer not less than 15 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 facing tiles, carpet, linoleum or painting, without applying a self-leveling mortar. The self-leveling mixture Master “Nivelir Finish” can be laid on the layer of Master “Nivelir Start”.
