The warm floor is laid on the heat -insulating material, the thickness of which is at least 2 cm. Then we lay a light reinforcing grid. It prevents the contact of the cable with the heat -insulating material. The cable is laid in a spiral, keep the distance between the turns. Make sure that the cable does not cross - this will lead to a closure. A special sensor is also installed, which is responsible for the work of the warm floor. It is necessary to bring to the wall the thermostat with which you will adjust the temperature regime of the warm floor. Before pouring the screed, do not forget to check the system performance. To do this, just connect it to the outlet. After that, the final screed is poured. It will close the warm floor evenly and will serve as the basis for laying any floor covering.
