and S4, performing self-leveling pouring of the thick layer.

If the heat-insulating layer is a foam board or foamed cement, in steps S2 and S3, the heat-insulating layer and the base layer, and the floor heating coil and the heat-insulating layer are respectively fixed by bonding mortar, so that the heat-insulating layer and the floor heating coil are prevented from floating after the thick-layer self-leveling cement is filled in step S4.

And the discharge port is perpendicular to the construction surface during pouring, and parallel pouring from inside to outside is ensured, so that the self-leveling mortar is uniformly distributed and poured to the elevation line. After the pouring is finished and the drying is finished, the height difference of the formed plane is not more than 2mm/2 m.
