For different waterproof parts of buildings, corresponding waterproof materials shall be selected for construction. The waterproof materials of buildings are selected according to different parts. Some parts are suitable for waterproof coiled materials, some parts are suitable for waterproof coatings, etc., and the waterproof requirements of each part are also different. Each waterproof material has its own strengths and weaknesses. One material can not cover the world. There is no good material used anywhere. All kinds of materials can only complement each other, not be replaced, and each has its own place to play. Roof waterproofing and basement waterproofing require different material properties, while bathroom waterproofing and wall waterproofing are more different. Sloping roofs, roofs with complex shapes and metal plate base roofs are also different, so they should be carefully selected.

1、屋面防水层暴露在大自然中，受到炎热日光的暴晒，狂风的吹袭，雨雪的侵蚀，严寒酷暑的温度折磨，昼夜温差的变化胀缩反复，没有优良的材性和良好的保护措施，难以达到要求的耐久年限。所以应选择抗拉强度高、延伸率大、耐老化好的防水材料，建议屋面用聚氨酯类防水涂料。

1. The waterproof layer of the roof is exposed to the nature, exposed to the hot sunlight, the wind, the rain and snow erosion, the temperature torture of severe cold and heat, the change of temperature difference between day and night, the expansion and contraction are repeated, and it is difficult to achieve the required durability without excellent material properties and good protection measures. Therefore, waterproof materials with high tensile strength, high elongation and good aging resistance should be selected. Polyurethane waterproof coating is recommended for roof.

2、墙体为什么渗漏，皆因现在墙体太薄，多为轻型砌块砌筑，大量内外通缝，再是门窗樘与墙的结合处，密封不严，雨水由缝中渗入。墙体防水不能用卷材，只能用防水涂料，而且和外装修材料结合。窗樘安装缝唯有密封膏才能解决问题，外墙防水建议用JS聚合物水泥基防水涂料三型的来做外墙防水。

2. The reason why the wall leaks is that the current wall is too thin, mostly built with light blocks, a large number of internal and external through joints, and the joint between the door and window frame and the wall is not tightly sealed, and the rainwater seeps through the joints. The wall can not be waterproof with coiled materials, but only with waterproof coatings, and combined with external decoration materials. Only sealing paste can solve the problem of window frame installation joint. It is recommended to use js polymer cement-based waterproof coating for exterior wall waterproofing.

3、地下建筑防水选材，地下防水层长年浸泡在水中或十分潮湿的土壤中，防水材料耐水性好，建议地下室防水用水泥基渗结晶防水涂料

3. Waterproof material selection of underground buildings: the underground waterproof layer is immersed in water or very humid soil for many years, and the waterproof material has good water resistance. It is recommended to use cement-based permeable crystalline waterproof coating for basement waterproof

4、厕浴间的防水有三个特点。一是不受大自然气候的影响，温度变化不在，对材料的延伸率要求不高;二是面积小，阴阳角多，穿楼板管道多;三是墙面防水层上贴瓷砖，与粘结剂亲和性能好。根据以上三个特点，不能选用卷材，只有防水涂料更合适，建议卫生间防水用K11防水涂料、JS聚合物防水涂料

4. The waterproof of toilet and bathroom has three characteristics. First, it is not affected by the natural climate, the temperature does not change, and the requirements for the elongation of materials are not high; Second, the area is small, there are many internal and external corners, and there are many pipes passing through the floor; Third, the wall waterproof layer is pasted with ceramic tiles, which has good affinity with the binder. According to the above three characteristics, coiled materials cannot be selected, and only waterproof coating is more suitable. K11 waterproof coating and JS polymer waterproof coating are recommended for toilet waterproof

建筑物做防水，一定要选对合适的防水材料，这样才能更好的发挥防水材料的功能，才会起到很好的防水效果。

To make buildings waterproof, we must choose the right waterproof materials, so as to give better play to the function of waterproof materials and play a good waterproof effect.
