After the office is decorated and used for a period of time, a lot of owners will find that under the door jamb of the room, it is especially moldy and black, especially under the door jamb of the toilet. However, how to deal with and solve these problems is very troublesome. If you want to dismantle and repair in the construction is particularly troublesome, then what kind of reasons will cause mildew and blackening under the door jamb? How can we prevent similar things from happening? How can we prevent the door from mildew? The following is the answer.

　　首先我们讨论下面的办公室洗手间的门盖黑为什么容易发霉,这篇文章的原因墙造型大体相似,是一个主要的建筑,不懂施工工艺和建筑工人是图省事,不按照施工的施工工艺,在墙面潮湿不是完全干燥在一种工作在建设中,首先是把大门上。由于墙壁或潮湿导致墙壁内的水汽无法挥发，被门完全吸收罩住受潮，时间就产生了发霉的黑色现象。还有就是厨房和卫生间门套上也非凡轻易洒水，如前期在未安装门套前不做墙壁防潮处理，后期门套也非凡轻易发霉腐烂。尤其是卫生间的门套。

　　First of all, we will discuss why the door cover of the office washroom below is black and moldy. The reason for this article is that the shape of the wall is generally similar. It's a main building. It's easy to understand the construction process and the construction workers' drawings. It's not according to the construction process. When the wall is wet or not completely dry, it's a kind of work in construction. First, it's to put the door on. Because the water vapor in the wall cannot volatilize due to the wall or humidity, it is completely absorbed and covered by the door and affected by the humidity, and the mildew black phenomenon occurs in time. There is even kitchen and bathroom door cover also particularly easy to sprinkle water, such as in the early days before the door cover is not installed do not do wall moisture-proof treatment, late door cover is also particularly easy to moldy rotten. Especially the door pocket of the toilet.

　　那么该如何施工，避免门套发霉、门套根部腐烂的情况发生呢?我们要按照标准施工工艺建造，门套下面的墙体和门套首先要做好防潮、防腐处理，然后再按照相应的程序安装。一般卫生间都有挡水板，可以比卫生间内地砖高一点。在安装钢板时需要刷上底漆，起到防腐和防潮的作用。卫生间持水板与门套之间要留出一点缝隙，这样卫生间的水会顺着地面流去，而不会顺着门套上铺，门套也不会因此受潮发霉、变黑。

　　So how to construct? We should build according to the standard construction process. The wall and door cover under the door cover should be moistureproof and antiseptic first, and then install according to the corresponding procedures. Generally, the toilet has a water baffle, which can be a little higher than the floor tiles in the toilet. When installing the steel plate, the primer shall be applied to prevent corrosion and moisture. There should be a gap between the water holding plate and the door pocket in the toilet, so that the water in the toilet will flow down the ground, and will not be laid along the door pocket, and the door pocket will not be damp, moldy and black.

　　处理门套霉变发黑的方法，当然更主要的是做好基层防潮、防腐处理。在选材时还有卫生间门套尽量选用一些防腐防水的材料。

　　Of course, the most important way to deal with the door jamb is to do a good job of moisture-proof and anti-corrosion treatment. When selecting materials, try to choose some anticorrosive and waterproof materials for the door pocket of the toilet.

　　假如办公室卫生间全部采用铝合金门覆盖，那么就不会大担心防水问题。根据有关规定，只要与卫生间墙面所接触的门套一定要做防潮处理。所以在装修房子的时候，业主不妨多花点时间在以下几个施工方面仔细观察一下工人。

　　If office toilet uses aluminium alloy door to cover completely, so won't worry about waterproof problem greatly. According to the relevant regulations, as long as the door jamb contacted with the toilet wall must be treated against moisture. So when decorating the house, the owner may as well spend more time to observe the workers carefully in the following aspects of construction.

　　一是在门的背面多涂几次清漆。墙面与卫生间门套的细木工板接触的地方，是细木工板的背面，一定要刷清漆，一定要多刷几遍，这样可以阻隔体内的水分不被门套所吸收。

　　One is to apply more varnish on the back of the door. The place where the wall meets the joinery board of the door pocket of the toilet is the back of the joinery board, which must be painted with varnish and painted several times, so as to prevent the moisture in the body from being absorbed by the door pocket.

　　二是如厕所内无门槛石，则应在门盖与地面之间留出1°左右的缝隙，以防止厕所地面的水渗入门盖。

　　Second, if there is no threshold stone in the toilet, a gap of about 1 ° shall be left between the door cover and the ground to prevent the water on the toilet floor from permeating into the door cover.

　　其三是在卫生间门套的后面贴上一层防潮板，这样也可以隔绝墙壁的水汽渗透到门套里面。

　　Third, a layer of moisture-proof board is pasted on the back of the door pocket of the toilet, which can also isolate the water vapor of the wall from penetrating into the door pocket.

　　其四就是选择门套线时，尽量选择一些耐水、防水好的一些材料，例如石材、瓷砖。

　　Fourth, when choosing the door jamb line, try to choose some water-resistant and waterproof materials, such as stone and ceramic tile.

　　办公室门套防霉是需要注重的，请大家选择好的装修公司避免这种现象的发生。
