卫浴间在我们日常生活中是必不可少的，如果说防水问题解决不好的话，不仅给很多家庭带来了不必要的经济损失，还可能破坏原本和睦的邻里关系。怎样才能做好卫浴间的防水呢？
一、重铺地砖要做地面防水
如果需要更换卫生间原有地砖，将原有地砖凿去后，一定要先用水泥砂浆将地面找平，再做防水处理，这样就可以避免防水涂料因厚薄不均而造成渗漏。在做防水之前，一定要将地面清理干净，用聚氨酯防水涂料反复涂刷2至3遍。墙与地面之间的接缝及上下水之间的管道地面接缝处，是最容易出现问题的地方，一定要督促好工人处理好这些边边角角，防水涂料一定要涂抹到位。要求装修队给厨房、卫生间的上下水管一律做好水泥护根，从地面起向上刷10至20厘米的聚氨酯防水涂料，然后地面再重做聚氨酯防水，加上原防水层，组成复合性防水层，以增强防水性。
If you need to replace the original bathroom tiles, floor tiles after the original chipped away, be sure to leveling the ground with cement mortar, waterproofing treatment do so because of uneven thickness waterproof coating resulting in leakage can be avoided. Before waterproof, be sure to clean the floor with polyurethane waterproof coating repeatedly brushing 2-3 times. Pipe joints and seams ground between the upper and lower water between the wall and the ground, is where most prone to problems, we must urge the good workers deal with these corners, waterproof coating must be applied in place. Requires renovation team to the kitchen, the bathroom and down pipes always make cement mulch, brush from the ground up 10-20 cm of polyurethane waterproof coating, then ground and then redo polyurethane waterproofing, plus the original waterproof layer, waterproof layer composite composition, to enhance water repellency.
二、用24小时“蓄水试验”验收防水
在防水工程做完后，封好门口及下水口，在卫生间地面蓄满水达到一定液面高度，并做上记号，24小时内液面若无明显下降，特别楼下住家的房顶没有发生渗漏，防水就做合格了。对于轻质墙体防水施工的验收，应采取淋水试验，即使用水管在做好防水涂料的墙面上自上而下不间断喷淋3分钟，4小时以后观察墙体的另一侧是否会出现渗透现象，如果无渗透现象出现即可认为墙面防水施工验收合格。
After the waterproofing works done, the door seal and drain in the bathroom floor fills the water level reaches a certain height, and cook mark, within 24 hours if no level decreased significantly, especially in the roof of the home downstairs did not happen leakage, waterproof qualified to do. For acceptance waterproof lightweight wall construction, water spray test should be taken that the use of sprinkler pipes from top to bottom uninterrupted good waterproof paint on the wall three minutes, the other side of the wall was observed after 4 hours if penetration phenomenon occurs, if no penetration phenomenon can be considered wall waterproofing acceptance.
三、一定要做墙面防水
卫生间洗浴时水会溅到邻近的墙上，如没有防水层的保护，隔壁墙和对顶角墙易潮湿发生霉变。所以一定要在铺墙面瓷砖之前，做好墙面防水。与淋浴位置邻近的墙面防水也要做到1.8米高，若使用浴缸，与浴缸相邻的墙面防水涂料的高度也要高于浴缸的上沿。
When bathing water splash bathroom adjacent wall, as no protective waterproof layer, next to walls and vertical angles easy to damp moldy walls. So be sure to shop before the wall tiles, good waterproof wall. Nearby walls and shower water should be 1.8 meters high, if the use of a bathtub, and the adjacent wall waterproof coating bath height is higher than the upper edge of a bathtub.
四、尽量不破坏原有防水层
现在普遍存在的问题是，装修中会增加一些卫生间的洗浴设施和对多种上下水管线进行重新布局或移动，本身已经严重破坏建筑物原有的防水层，但是，没有修补或重新做防水施工，以至于发生渗漏后才发现问题。在新交付使用的楼房中，卫生间、浴室和厨房的地面都有按照相关规范做的防水层，所以，不破坏原有的防水层入住后一般是不会发生渗漏情况的。防水层在重新装修地面时易被破坏，要及时修补，以免留下隐患。
Common problem now is that the decoration will add some bathroom amenities and a variety of water lines down or move to re-layout, the building itself has been seriously undermined the original waterproof layer, however, no repair or re-do waterproof construction that leakage occurs after the discovery of the problem. In the delivery of new buildings, toilet, bathroom and kitchen on the ground has done in accordance with the relevant specifications waterproof layer, therefore, does not undermine the general is not going to happen after the original occupancy leakage of waterproof layer. Waterproof layer in the renovated ground easily damaged to be repaired, so stay hidden.
五、墙内水管凹槽也要做防水
施工过程中在管道、地漏等穿越楼板时，其孔洞周边的防水层必须认真施工。墙体内埋水管，做到合理布局，铺设水管一律做大于管径的凹槽，槽内抹灰圆滑，然后凹槽内刷聚氨酯防水涂料。厨房、卫生间的地面必须坡向地漏口，适当加大坡度，厨房、卫生间内管道装修时应尽量避免改动原来的排水和污水管道及地漏位置，避免因重新排管凿楼板损坏防水层引起渗漏。
The construction process in the pipeline to leak through the floor, its holes around the waterproof layer must be carefully and construction. Buried pipes in the wall, so that rational distribution, laying water pipes shall be made ??larger than the diameter of the groove, the groove smooth plaster, then brush polyurethane waterproof coating groove. Kitchen, bathroom floor must slope to drain port, due to increase slope, kitchen, bathroom renovation pipeline should avoid changes to the original drainage and sewage pipes and drain position, to avoid damaging the floor chisel reschedule tube waterproof layer caused by leakage .
