衛浴間在我們日常生活中是必不可少的，如果說防水問題解決不好的話，不僅給很多家庭帶來了不必要的經濟損失，還可能破壞原本和睦的鄰里關系。怎樣才能做好衛浴間的防水呢？
一、重鋪地磚要做地面防水
如果需要更換衛生間原有地磚，將原有地磚鑿去后，一定要先用水泥砂漿將地面找平，再做防水處理，這樣就可以避免防水涂料因厚薄不均而造成滲漏。在做防水之前，一定要將地面清理干凈，用聚氨酯防水涂料反復涂刷2至3遍。墻與地面之間的接縫及上下水之間的管道地面接縫處，是最容易出現問題的地方，一定要督促好工人處理好這些邊邊角角，防水涂料一定要涂抹到位。要求裝修隊給廚房、衛生間的上下水管一律做好水泥護根，從地面起向上刷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，加上原防水層，組成復合性防水層，以增強防水性。
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小時“蓄水試驗”驗收防水
在防水工程做完后，封好門口及下水口，在衛生間地面蓄滿水達到一定液面高度，并做上記號，24小時內液面若無明顯下降，特別樓下住家的房頂沒有發生滲漏，防水就做合格了。對于輕質墻體防水施工的驗收，應采取淋水試驗，即使用水管在做好防水涂料的墻面上自上而下不間斷噴淋3分鐘，4小時以后觀察墻體的另一側是否會出現滲透現象，如果無滲透現象出現即可認為墻面防水施工驗收合格。
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、一定要做墻面防水
衛生間洗浴時水會濺到鄰近的墻上，如沒有防水層的保護，隔壁墻和對頂角墻易潮濕發生霉變。所以一定要在鋪墻面瓷磚之前，做好墻面防水。與淋浴位置鄰近的墻面防水也要做到1.8米高，若使用浴缸，與浴缸相鄰的墻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、盡量不破壞原有防水層
現在普遍存在的問題是，裝修中會增加一些衛生間的洗浴設施和對多種上下水管線進行重新布局或移動，本身已經嚴重破壞建筑物原有的防水層，但是，沒有修補或重新做防水施工，以至于發生滲漏后才發現問題。在新交付使用的樓房中，衛生間、浴室和廚房的地面都有按照相關規范做的防水層，所以，不破壞原有的防水層入住后一般是不會發生滲漏情況的。防水層在重新裝修地面時易被破壞，要及時修補，以免留下隱患。
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、墻內水管凹槽也要做防水
施工過程中在管道、地漏等穿越樓板時，其孔洞周邊的防水層必須認真施工。墻體內埋水管，做到合理布局，鋪設水管一律做大于管徑的凹槽，槽內抹灰圓滑，然后凹槽內刷聚氨酯防水涂料。廚房、衛生間的地面必須坡向地漏口，適當加大坡度，廚房、衛生間內管道裝修時應盡量避免改動原來的排水和污水管道及地漏位置，避免因重新排管鑿樓板損壞防水層引起滲漏。
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 .
