Ceresit CN 87 is used for laying floor foundations:
- associated with a cement base, 10 to 80 mm thick,
- on a separating layer (e.g. foil, paper), thickness from 35 to 80 mm,
- "floating" on a layer of thermal or sound insulation, thickness from 45 to 80 m. For underfloor heating - the minimum thickness of 45 mm should be increased by the outer diameter of the conductor in heating.
The mortar mixed with water has a dense plastic consistency, allowing the formation of slopes. Primers and floors made of CN 87 (non-reinforced or reinforced) can be used inside or outside buildings. Screeds of mortar CN 87 can be used as the final wear layer, you can also lay ceramic tiles, parquet, make resin floors, or pour floors with Ceresit and Thomsit self-leveling or spreading mortars.
