Precautions for waterproofing in the bathroom
2021-11-12 11:03
The waterproofing of the bathroom should be checked for the correct elevation of the kitchen and bathroom, and special attention should be paid to the correct elevation position of the floor drain. Careful inspection should be carried out on the quality of the wall holes at the bottom of the floor drain and pipeline. The wall holes should be compacted and qualified. During the construction of the leveling layer, the pipeline roots should be filled with joints as required. The yin-yang angle should be made into a circular arc shape, and should be straight and flat. Leveling layer construction: The waterproof layer construction can only be carried out after the leveling layer is dry. During the construction period, fire prevention and waterproofing should be carried out. Construction personnel should wear soft soled shoes. After the waterproof layer is completed, finished product protection should be carried out. After passing the inspection and confirmation, the concealed engineering acceptance visa can be processed before proceeding to the next construction process.
If it is necessary to replace the original floor tiles in the bathroom, after chiseling off the original tiles, the ground should be leveled with cement mortar first, and then waterproof treatment should be carried out to avoid leakage caused by uneven thickness of waterproof coating. Before waterproofing, the ground should be cleaned and the polyurethane waterproof coating should be repeatedly applied 2-3 times.
The ground level should be tilted towards the floor drain. The kitchen floor can be flat, as there are not many opportunities for water to accumulate on the kitchen floor, while there is often water on the bathroom floor. In the same "water storage space", the floor drain should be low, otherwise, the water accumulation in the bathroom can be very troublesome.
