刮完兩遍膩子，但用手指搓會掉粉，造成這種現象的原因有很多:
After scraping the putty twice, the powder will be removed when rubbing with fingers. There are many reasons for this phenomenon:
(1)施工中如使用不防水膩子(如821膩子)，不加膠或界面劑，出現上述情況并不奇怪。
(1) it is not surprising that no waterproof putty (such as 821 putty), no glue or interface agent are used in the construction.
(2)使用防水膩子粉，膩子粉存在質量問題。如:防水膩子粉中膠粉的含量較低，或防水膩子粉用于白水泥、灰鈣等膠結材料的質量較差。
(2) the use of waterproof putty powder has quality problems. For example, the content of rubber powder in waterproof putty powder is low, or the quality of waterproof putty powder used in white cement, gray calcium and other cementitious materials is poor.
(3)現場配制膩子粉，采用108膠與滑石粉、重鈣粉直接混合，不添加水泥、灰鈣、石膏等無機膠凝材料，導致配制的膩子粉強度低。
(3) the putty powder is prepared on site, which is directly mixed with 108 glue, talcum powder and heavy calcium powder, without adding cement, grey calcium, gypsum and other inorganic cementitious materials, resulting in low strength of putty powder.
(4)施工人員為了刮擦，將膩子粉調配成低強度、柔軟的粉末。
(4) in order to scrape, the construction personnel will mix the putty powder into low strength and soft powder.
