我很多业主不愿意购买顶楼的户型，就是怕顶楼漏水或者不隔热，其实只要在装修的时候将防水隔热方面做好之后是不用太担心会漏水的，且顶楼采光通风条件都很不错，居住起来也安静，很多开发商的顶楼在价格上还会有一定的优惠，因此只要做好防水顶楼也是不错的选择。那么我怎么装修防漏水呢?下面来看相关介绍。

1、防水层选择

对漏水区域重新设置适宜于外露使用的防水层。防水材料如果是选用的防水卷材，建议采用国标3mm聚酯胎铝膜SBS，并对卷材搭接处进行密封处理，实现无缝防water。

2、增强防water

对热water器根部、出屋面管道、阴阳角等部位进行附加增强处理。不管是何种原因导致top floor water leak，我们都得要修复，首先就得要找到leak 的位置，如果是有裂缝，那么就把cement sand凿开成v形，然后用defensive material刷，然后再过一层cement sand不过面积要大，厚度要高。还有，在cement sand边缘用界机界一条槽，这样就会粘得牢固。

3、pipe place water leak handling

如果是从pipe place water leak下来，那么可能在安装过程中出现问题，也可能是pipe material quality problem，这个就要详细地检查了。

4、redo defensive layering

不能找到leak 的spot of the roof, suggest redo protective layering choose defensive paint. Can perform multiple applications, multiple layers set up defense. Complete protective layer painting frequency is twice, total thickness not exceeding 2mm, then apply cement and sand for protection layer. After protection layer solidifies again perform complete protective layer painting once more, then use cement and sand for protection layer. Then again apply flexible type protective paint.

5、preventing top floor from leaking away method

Directly from root level solve it without damaging roof insulation or waterproofing layers directly on top of them lay tile and wood flooring then seal with glass to create a rooftop sunroom like this design doesn't matter if you treat it as a drying area in winter or a spot to hang out with friends all good views are wide open great way to relax.

6、prevent external leakage

So called prevent external leakage means preventing indoor space from seepage if seepage hazards come from windows balconies reasons lie in aluminum alloy window installation when waterproofing preventive measures don't meet standards or aren't qualified causing every time rain comes there's seepage phenomenon. If no change during renovation just take remedial measures install new window ledges fill gaps around old seals reapply waterproof sealant outside part dig up original waterproof adhesive reseal with new one.

By following these steps my own top floor can be safely enjoyed without worrying about leaks or poor heat insulation!
