引起基面含水量過高的原因有哪些?目前要求絕大部分建筑的漆系統需要具備防水層(DPM)。防水層一般是通過在地面基層上/下鋪蓋聚乙烯防水材料或者瀝青防水材料來形成的。潮濕度過大會導致流體靜壓作用，比如地下水會滲出基面等。一般具備防水膜或者水槽或排水管道的系統是不會出現這種情況的。但是我們也要注意，如果僅具備排水管道，但沒有防水層的系統，我們需要進行基面水分測試，并結合其他相關因素進行考慮，比如說地下水位等。嚴重的流體靜壓作用甚至對導致面層失效。

What are the reasons for the high moisture content of epoxy floor paint? At present, most of the building epoxy floor paint systems need to have waterproof layer (DPM). Waterproofing layer is usually formed by laying polyethylene waterproofing material or asphalt waterproofing material on or under the ground base. Excessive humidity can lead to hydrostatic effects, such as groundwater seeping out of the base surface. This is not the case for epoxy flooring systems with waterproof membranes or flumes or drainage pipes. But we should also pay attention to the fact that if there are only drainage pipes but no epoxy floor system with waterproof layer, we need to test the moisture of the base surface and consider other relevant factors, such as groundwater level. Severe hydrostatic pressure may even lead to the failure of the floor surface. 許多樹脂系統無法在高含水量的基面上使用，因此，如果再使用這種漆材料會使得底涂層在完工前出現受潮現象，而且很可能導致整個系統在涂裝完成后，牢固度大受影響，從而引起面層起泡、分層，甚至失效。

Many resin flooring systems can not be used on high water content base surfaces. Therefore, if this epoxy flooring paint material is used again, the bottom coating will be damped before completion, and it is likely that the firmness of the whole epoxy flooring system will be greatly affected after finishing painting, which will cause foaming of the epoxy flooring surface. Layering, or even failure.

一般來說，只有出現以下幾種原因，才會導致基面含水量過高：

Generally speaking, only the following reasons can lead to excessive water content in the base surface:

1、未配備防水層的現代建筑

1. Modern Buildings without Waterproof Layer

有些建筑類型，比如倉庫或者物流中心等，本身并沒有實施系統，所以也沒有防水層。但是一旦將其改建為其他功能的建筑，那么含水量過高的問題就會顯現。

Some building types, such as warehouses or logistics centers, do not implement floor systems themselves, so there is no waterproof layer. But once it is converted into other functional buildings, the problem of excessive water content will emerge.

2、基面完工時間短或未干透

2. Short or not thoroughly dried base surface

大量的實踐證明，基面完工后讓其自然風干的效果最佳，否則很可能會導致完工后系統出現各種問題。但是現代化的建造速度往往無法耗費大量工時，所以使用樹脂材料作面涂層的方式越來越流行。

A large number of practices have proved that the effect of natural air-drying is the best after the foundation is completed, otherwise it may lead to various problems in the floor system after completion. However, modern construction speed often can not consume a lot of time, so the use of resin materials for surface coating is becoming more and more popular.

3、防水層失效

3. Failure of Waterproof Layer

防水層可能會出現失效的情況，雖然導致其失效的原因有很多種，但是通常來說都是由于涂裝不正確，或者涂裝期間防水層被損壞，比如被鋼筋刺穿等。

Waterproof layer may fail, although there are many reasons for its failure, but usually it is due to improper painting, or the waterproof layer is damaged during painting, such as pierced by steel bars.
