在施工過程中遇到含水量過高的基面，一定要采取準確的防水方案，才能避免日后系統出現問題。做施工的都知道，施工時如果基面的含水率高的話會導致剛做好的漆膜有水泡溢出，進而導致地坪漆膜破裂，影響地坪的使用。那么引起基面含水量過高的原因有哪些呢？又該如何進行解決？

基層含水量過高的原因

Reasons for Excessive Water Content of Epoxy Floor Base

導致基面含水量過高的原因有兩個，一是建筑本身沒有配備防水層，一旦進行改建就會出現含水量過高的問題。

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.

另一個方面是在基面完工后，地面沒有干透，或者是涂裝的防水層已經失效，導致基面的含水量過高。

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.

解決方案：

Solution:

1、防潮底涂層

1. Moistureproof Base Coating

現在的地坪材料中有針對基面含水量高的專業防潮底涂產品，對系統而言具有長遠的保護作用，使用范圍較廣。

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、尺度底涂層

2. Scale bottom coating

在一些特殊情況下，根據基地含水量程度，我們在涂裝尺度樹脂地坪系統時，需要涂裝尺度底涂層。

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、專業基面防水層

3. Professional Base Waterproof Layer

一般情況下，在地下室或者地下停車場等區域，由于環境問題，會鋪設專業的基面防水層，或者通過涂裝一層防滲透涂層來達到防水的效果，適用于含水量不斷上升的基面。這種防滲透滲出產品主要是在樹脂地坪系統完成后，用來防止水位升高引起的滲水現象進行的保護手段。

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、透濕系統

4. Moisture permeability system

彌補了底涂層和樹脂面涂層無法達到的防潮性，目前很多出產商都已開發出透濕系統。透濕系統是為了保證材料的水蒸氣透過率，也適用于無法裝備防水層的基面。
