Is wall mildew related to putty powder?

　　墙壁霉变的原因无非是潮湿的原因，一种是季节原因而引起的潮湿，这与孩子粉红色的关系不大。一种是墙体基层没有做好基面处理不好，这种情况可能有腻子粉的原因。

　　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. 墙体保温失效导致墙体发霉:先检查墙体是否已保温。如果声音是中空的，那么墙壁就有保温层。如果声音沉闷，则说明墙体没有做保温层。如有保温层，应检查建筑物外墙是否有裂缝。如果没有裂缝，说明保温材料不好，需要更换，这是根治的方法。此外，墙壁不防水，这导致水渗漏和霉变的墙壁。

　　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、因季节原因引起霉变:好不要立即修复。由于墙体内的水分逐渐挥发，属于装饰材料的正常物理变化。如果你在水完全蒸发之前穿上一件新外套，水会继续蒸发，从其他地方冒出来，墙壁又会发霉。

　　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.

　　现在腻子粉一般是水性腻子粉，其中含有钙灰粉，所以发霉的主要原因有以下三点:

　　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，阳台、卫生间用了内壁腻子粉，由于阳台经常会因雨天、日晒雨淋而接触水，卫生间经常洗澡使里面很潮湿，也可能发霉。

　　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.

　　解决的方法:预防为主，如知道建筑物某处渗水或阳台、卫生间等潮湿的地方，施工时用外墙腻子粉或中性乳胶漆覆盖。由于监督，次不要使用外墙腻子粉施工而发霉的墙面，解决的方法是将发霉处打磨，滚刷乳胶漆或铲掉，刮掉外墙腻子粉。

　　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.
