The surface of the leveling layer should be kept gross surface, not too smooth, in the construction, can increase the proportion of mortar, this is to increase the bonding force of the wall, so as not to cause inconvenience to the construction of the later stage. And during construction, an appropriate amount of waterproofing agent should be added to avoid erosion by rain.

Meanwhile in the construction of the exterior wall, must pay attention to the temperature problem, should not be in the temperature is too low environment construction, drying time will become longer.
