<P>Moisture content of the floor, if the installation is not in place, there will be deformation. Because the air is very dry, in the 30 to 60 days of construction period, the floor potential dry crack, deformation and other issues will be exposed. Laying the floor in winter, special attention should be given to the construction of appropriate gaps, the floor should be around 2 mm expansion joints, or prone to drums, dangling phenomenon.</P>
<P>In addition, in the case of geothermal, we must pay attention to step by step to heat the floor. Before installation, the concrete floor temperature should be gradually increased by 5 �� every day until it reaches about 18 �� so far. In the first 3 days after the installation is completed, to maintain this temperature, after 3 days can be warmed up as needed. Can not heat up too fast, otherwise the floor may crack due to bulging distortion phenomenon.</P>
