In order to make the house watertight, we must first change the inherent ideas of people, recognize the importance of waterproofing, and Secondly ensure that the house does not leak in the choice of materials and construction technology.
For example, water corrosion and damage to the structure is invisible, or when purchasing, select some inferior and toxic waterproof materials, and do not cooperate with professional waterproof construction units, but do not know the mold and air pollution caused by water seepage It affects Our living environment and physical and mental health.

6, brush thickness waterproof coating must be brushed to the national acceptance specification of 1.5 mm thick.
Key waterproof parts in the bathroom:
Floor drains, small water pipes and floor joints, and toilet pipes are often the most leaky places in the bathroom. At the time of construction, it is necessary to focus on these parts. Generally, the other parts are brushed twice, and it is necessary to brush multiple times here; in addition, more leakage appears below the door stone.

In general, bathroom, kitchen and balcony waterproofing are the key waterproofing projects in home renovation. However, there are other special areas in the home that need to be waterproofed. For example, in the basement of some villas, as well as in the first floor area of ​​some residential houses, it is common practice to apply a waterproof paste and then perform the veneer construction. In addition, in the northern region, due to the winter climate, waterproofing projects are also indispensable for some homes that install floor heating. Because of the large temperature difference between indoor and outdoor in winter, the geothermal pipeline close to the door and window is prone to condensed water and penetrates into the concrete structure below. Therefore, before laying the floor heating pipe, it is necessary to apply the waterproof coating first, then do the leveling layer, the floor heating and moisturizing layer, and then laying the floor heating pipe.
