1. After completing the processing of masonry, installation equipment, pipelines, etc. If the house is paved, it should be carried out in the order of high and low, first, then far and near. When a single -span labeling, first pave the place where the drainage is relatively concentrated (such as the falling water mouth, the eaves, the oblique ditch, the heavenly ditch, etc.), and the high to the high, the ramp surface and the facade coil at the elevation level Start from the bottom to the top, so that the coils are overlap in the direction of the water flow.
2. When the coil parallel roof ridges are paved, the long side is overlapped at about 70 mm, and the short -sided overlap at about 150 mm. The short side of the two adjacent coils should be staggered by not less than 500 mm. The width of the overlap and the paving straight, the marking line should be popped up when paving the coils. The arched roof with a slope of more than 5%and the slope under the sunroof should be as short as possible.
3. Before the waterproof layer is paved, you should first find the flat layer for drying. The method of on-site testing: within the evening to the morning or the sunny day or about 1-2 hours of sunny, it is covered with 1 square meters. When exposed, it was thought that the flat layer was basically dry.
