The cause of wall mildew is nothing more than moisture caused, a kind of humidity caused by seasonal reasons, which has little to do with putty powder. One is that the base course of the wall is not well done, and the base surface is not treated well, which may be caused by putty powder.

一据途、因?yàn)閴w保溫沒有做好而導(dǎo)致的墻體發(fā)霉：應(yīng)先檢查墻體是否做過(guò)保溫處理泄鹏。用檢查錘敲擊墻面实胸，如果聲音空洞他嫡，則說(shuō)明墻體有保溫層，如果聲音沉悶庐完，則說(shuō)明墻體沒有做保溫層钢属。

1、 Because the wall insulation is not done well and caused by mildew: should first check whether the wall has done insulation treatment. If the sound is hollow, it means that the wall has insulation layer. If the sound is dull, it means that the wall has no insulation layer.

若存在保溫層則需檢查建筑外墻是否存在裂縫假褪，如果沒有裂縫署咽，說(shuō)明保溫材料不行，要進(jìn)行更換生音，這是根治之法宁否。還有墻體沒做防水導(dǎo)致墻體滲水引起墻壁發(fā)霉。

If there is thermal insulation layer, it is necessary to check whether there are cracks in the external 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 a radical method. There is no waterproof wall, resulting in wall water seepage, causing the wall moldy.

二缀遍、因?yàn)榧竟?jié)原因造成的發(fā)霉：更好不要馬上修補(bǔ)慕匠。因?yàn)閴w內(nèi)的水分正在逐漸揮發(fā)，屬于裝飾材料的正常物理變化域醇。如果未等水分完全揮發(fā)完就又刷上新的漆面隔阔，水分仍然會(huì)繼續(xù)揮發(fā)，并且還會(huì)從其他地方出來(lái)肖升，墻體就有可能再次發(fā)霉贵式。

2、 Mildew caused by seasonal reasons: it is best not to repair immediately. Because the water in the wall is gradually volatilizing, which belongs to the normal physical change of decorative materials. If you don't wait for the water to completely evaporate and brush a new paint surface, the water will continue to volatilize, and will come out from other places, the wall may become moldy again.
