Is wall mildew related to putty powder?

　　墻壁霉變的原因無非是潮濕的原因，一種是季節原因而引起的潮濕，這與孩子粉紅色的關系不大。一種是墻體基層沒有做好基面處理不好，這種情況可能有膩子粉的原因。

　　The cause of wall mildew is nothing more than dampness. One is seasonal dampness, which has little to do with children's pink color. One is that the base of the wall is not well treated, which may be the cause of putty powder.

　　1. 墻體保溫失效導致墻體發霉:先檢查墻體是否已保溫。如果聲音是中空的，那么墻壁就有保溫層。如果聲音沉悶，則說明墻體沒有做保溫層。如有保溫層，應檢查建筑物外墻是否有裂縫。如果沒有裂縫，說明保溫材料不好，需要更換，這是根治的方法。此外，墻壁不防水，這導致水滲漏和霉變的墻壁。

　　1. Wall insulation failure causes wall mildew: first check whether the wall has been insulated. If the sound is hollow, then the wall has insulation. If the sound is dull, it means that the wall is not insulated. If there is an insulating layer, check whether there are cracks in the exterior wall of the building. If there is no crack, it means that the insulation material is not good and needs to be replaced. This is the radical cure method. In addition, the walls are not waterproof, which leads to water leakage and moldy walls.

　　二、因季節原因引起霉變:好不要立即修復。由于墻體內的水分逐漸揮發，屬于裝飾材料的正常物理變化。如果你在水完全蒸發之前穿上一件新外套，水會繼續蒸發，從其他地方冒出來，墻壁又會發霉。

　　2. Mould caused by seasonal reasons: It is better not to repair it immediately. Due to the gradual volatilization of water in the wall, it belongs to the normal physical changes of decorative materials. If you put on a new coat before the water evaporates completely, the water will continue to evaporate and come out of other places, and the walls will become moldy again.

　　現在膩子粉一般是水性膩子粉，其中含有鈣灰粉，所以發霉的主要原因有以下三點:

　　Now putty powder is generally water-based putty powder, which contains calcium ash powder, so the main reasons for mildew are as follows:

　　，房子有漏水或滲水的情況，漏水或滲水的地方，因為長時間潮濕，會發霉，不要說膩子粉，長時間潮濕的地方，衣服應該發霉。

　　First, the house has leaks or seepage, leaks or seepage place, because long time wet, will be mildewed, do not say putty powder, long time wet place, clothes should be mildewed.

　　第二，建筑物長而潮濕，建筑物內回水，使墻面和天花板變得很潮濕，也會大面積發霉

　　Secondly, the building is long and humid, and the backwater inside the building makes the walls and ceilings very humid, and it also causes large areas of mildew.

　　第三，陽臺、衛生間用了內壁膩子粉，由于陽臺經常會因雨天、日曬雨淋而接觸水，衛生間經常洗澡使里面很潮濕，也可能發霉。

　　Third, the balcony, bathroom used putty powder, because the balcony often because of rain, sunshine and rain and contact with water, bathroom often bathed so that the inside is very humid, may also be mildewed.

　　解決的方法:預防為主，如知道建筑物某處滲水或陽臺、衛生間等潮濕的地方，施工時用外墻膩子粉或中性乳膠漆覆蓋。由于監督，次不要使用外墻膩子粉施工而發霉的墻面，解決的方法是將發霉處打磨，滾刷乳膠漆或鏟掉，刮掉外墻膩子粉。

　　Solutions: prevention is the main method, such as knowing the building somewhere seepage or balcony, bathroom and other wet places, construction with external wall putty powder or neutral latex paint cover. Due to supervision, for the first time, we should not use putty powder to construct mouldy walls. The solution is to grind mouldy areas, roll-brush latex paint or Shovel them off, and scrape off putty powder.
