衛生間裝修防水技巧

Waterproof skills of toilet decoration

一定要做墻面防水，在鋪墻面瓷磚之前，做好墻面防水。一般防水處理中墻面要做30厘米高的防水處理，但是非承重的輕體墻，就要將整面墻做防水，至少也要做到60厘米高。

Be sure to do wall waterproofing. Before laying wall tiles, do a good job in wall waterproofing. In the general waterproof treatment, the wall should be waterproof with a height of 30 cm, but for the non load-bearing light body wall, the whole wall should be waterproof, at least 60 cm high.

墻與地面之間的接縫及上下水之間的管道地面接縫處，是很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。

The joints between the wall and the ground and the ground joints of pipes between water supply and drainage are prone to problems. We must urge the workers to deal with these edges and corners, and the waterproof coating must be applied in place.

重鋪地磚要做地面防水如需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。

If the original floor tile of the toilet needs to be replaced, after the original floor tile is chiseled off, the ground must be leveled with cement mortar before waterproof treatment, so as to avoid leakage of waterproof coating due to uneven thickness.

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，然后凹槽內刷防水涂料。

The water pipe groove in the wall shall also be waterproof. During the construction process, when the pipe floor drain passes through the floor slab, the waterproof layer around the hole shall be carefully constructed. The water pipes shall be buried in the wall to achieve reasonable layout. The water pipes shall be laid with grooves larger than the pipe diameter. The plastering in the grooves shall be smooth, and then the grooves shall be painted with waterproof paint.

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。

After the waterproof project is completed, seal the door and water outlet, fill the toilet floor with water to a certain liquid level, and mark it. If the liquid level does not drop significantly within 24 hours, especially if there is no leakage on the roof of the house downstairs, the waterproof is qualified.
