在施工过程中遇到含水量过高的基面，一定要采取准确的防水方案，才能避免日后系统出现问题。做施工的都知道，施工时如果基面的含水率高的话会导致刚做好的漆膜有水泡溢出，进而导致地坪漆膜破裂，影响地坪的使用。那么引起基面含水量过高的原因有哪些呢？又该如何进行解决？

基层含水量过高的原因

Reasons for Excessive Water Content of Epoxy Floor Base

导致基面含水量过高的原因有两个，一是建筑本身没有配备防水层，一旦进行改建就会出现含水量过高的问题。

There are two reasons for the excessive water content in the foundation. One is that the building itself is not equipped with waterproof layer. Once rebuilt, the problem of excessive water content will arise.

另一个方面是在基面完工后，地面没有干透，或者是涂装的防水层已经失效，导致基面的含水量过高。

Another aspect is that after the completion of the base, the ground is not dry, or the waterproof coating has failed, resulting in excessive water content of the base.

解决方案：

Solution:

1、防潮底涂层

1. Moistureproof Base Coating

现在的地坪材料中有针对基面含水量高的专业防潮底涂产品，对系统而言具有长远的保护作用，使用范围较广。

Nowadays, there are professional moistureproof primer products with high moisture content on the base surface, which have a long-term protective effect on the epoxy floor system and a wide range of applications.

2、尺度底涂层

2. Scale bottom coating

在一些特殊情况下，根据基地含水量程度，我们在涂装尺度树脂地坪系统时，需要涂装尺度底涂层。

In some special cases, according to the water content of the base, we need to coat the scale base coatings when painting the resin floor system.

3、专业基面防水层

3. Professional Base Waterproof Layer

一般情况下，在地下室或者地下停车场等区域，由于环境问题，会铺设专业的基面防水层，或者通过涂装一层防渗透涂层来达到防水的效果，适用于含水量不断上升的基面。这种防渗透渗出产品主要是在树脂地坪系统完成后，用来防止水位升高引起的渗水现象进行的保护手段。

In general, in basement or underground parking area, due to environmental problems, professional waterproof layer will be laid on the base, or through the coating of a layer of impermeable coating to achieve waterproof effect, suitable for the rising water content of the base. This anti-seepage product is mainly used to prevent the seepage phenomenon caused by the rising water level after the completion of the resin floor system.

4、透湿系统

4. Moisture permeability system

弥补了底涂层和树脂面涂层无法达到的防潮性，目前很多出产商都已开发出透湿系统。透湿系统是为了保证材料的水蒸气透过率，也适用于无法装备防水层的基面。
