首先是流水面，即房屋的洗手间和厨房，因这两个部位常年有流水或经常潮湿，（屋顶）防水天然极其重要，万万不要掉以轻心。
The first is the water surface, which houses the Restroom and kitchen, because these two parts of perennial water or often wet, extremely important waterproof nature, don't let down.
其次是外露面，如阳台、天台、露台等，因其裸露在户外，长时间遭受雨水的侵蚀，亦必须进行有用的（屋顶）防水处理。
Followed by external appearances, such as balcony, terrace, roof, etc., because of its exposure to the outdoors, long suffering from erosion of rain, it is necessary to carry out effective water treatment.
再次是防潮面，通常指房屋的地面和墙面。房屋装修时墙体一样平常没有干透，肯定含有水分（建网站费用），且常有新砌墙或新铺水泥沙浆，若不做屋顶防水，水分就会往外蒸发，引起变色、起壳脱落和发霉等题目。分外是木地板、木质墙线和门框等木料部分，一旦渗入水分（建网站多少钱），就会因潮而变色、发霉、生虫，直至无法使用。
Once again, it is a damp surface, usually referring to the floor and walls of a house. When the building is decorated wall is generally not dry, with water, and often new walls or new cement mortar, if not waterproof, water will evaporate into the shell, causing discoloration, shedding and mildew problems. In particular, wood floors, wooden walls and door frames, such as wood, once the infiltration of water, it will be because of the tide and discoloration, mildew, insects, until it can not be used.
还有一个大家容易忽视但又须分外提示的是背水面（屋顶）防水，这重要是针对靠近建筑外墙的单元的用户。假如建筑商外墙面（屋顶）防水处理不到位，因长时间雨水冲刷，水分渐渐渗入居室的内墙面，若不做（屋顶）防水层阻隔，内墙墙纸、涂料等装饰材料就会遭殃。
There is an easy to ignore but must be reminded that the back surface of the water, which is mainly aimed at the building near the external walls of the unit users. If the building outer wall waterproofing treatment is not in place for a long time, the rain, the water gradually infiltrated into the inner wall of the living room, if not waterproof barrier layer, inner wall wallpaper, paint and other decorative materials will suffer.
