　　如何選擇質量好的膩子粉？根據有多年工作經驗的工人介紹，應該從膩子硬度、白度、細度、和易性、施工性能、環保等方面考慮，用肉眼很難分辨其好壞，和好膩子粘性大細膩為好膩子，反之，發散、有針孔的膩子質量差，用灰刀產一些和好膩子反過來很快就掉下來的粘性小。施工后等膩子干燥后手模不掉白、指甲不劃花、水刷不掉是好膩子。

　　How to choose putty powder with good quality? According to the workers who have many years of working experience, we should consider putty hardness, whiteness, fineness, workability, construction performance and environmental protection. It is difficult to distinguish putty from good putty by naked eyes. On the contrary, the quality of dispersed and pinhole putty is poor, and the stickiness of putty produced by grey knife and good putty falls down quickly is small. After construction, it is good putty that the hand mould does not drop white, the nails do not scratch, and the water brush does not drop after putty is dried.
