When we brush putty, only the first layer of putty is completely dried and then brushed for the second time, so we should learn to verify how to make putty in a completely dry state. For this reason, we can identify putty according to a variety of methods. The following four methods can be used for reference.

　　1. 視覺判斷。這是基本的一種判斷方法,膩子干會議后的顏色是白色的,如果有些地方仍然呈現(xiàn)讓恐慌或發(fā)送灰色的顏色,證明墻面膩子刷沒有徹底干燥。如果墻面完全干燥，則其色彩整體一致。

　　1. Visual judgment. This is the most basic judgment method. The color of putty after dry meeting is white. If some places still show the color of panic or send gray, the first proof is that the wall putty brush is not completely dry. If the wall is completely dry, its color is the same as a whole.

　　Palm-feel。膩子完全干燥后，可進(jìn)行第二次刷膩子。檢查基層膩子是否干燥有沒有簡單可行的方法，你只需用手掌觸摸墻面，假如膩子已干燥，手掌與墻面摩擦就會發(fā)出“沙沙”聲;也可以檢查手心，如果沾了很多灰塵，摸起來濕漉漉的感覺就可以斷定不干燥了。

　　Palm-feel. After the putty is completely dried, the putty can be brushed for a second time. Check whether the base putty is dry or not, there is a simple and feasible way, you only need to touch the wall with your palm, if the putty is dry, the palm and the wall friction will send out a "sand" sound; you can also check the palm, if it is stained with a lot of dust, the feeling of wetness can be determined not to dry.

　　使用砂紙。膩子干燥時，用砂紙輕輕打磨會產(chǎn)生粉塵;如果砂紙研磨;沒有灰塵或灰塵很少，那證實墻面膩子還沒有徹底干燥，絕對不能進(jìn)行兩次膩子的施工。

　　Use sandpaper. When putty is dry, lightly polishing with sandpaper will produce dust; if sandpaper is polished; there is no dust or little dust, it proves that the wall putty has not been completely dried, and it can never be constructed twice.

　　4. 粗略的時間估計。其實膩子干燥時間基本上可以估算，膩子性質(zhì)不同，時間也不同。普通膩子干燥至1- 3天，防水膩子至1周。季節(jié)不同，干燥時間也不同，一般夏天在2-3天就可以了，冬天假如需要5-7天，假如遇到陰雨天氣，那么時間就會拖長，具體情況還視整個家裝環(huán)境而定。

　　4. Rough time estimation. In fact, putty drying time can be basically estimated, putty properties are different, time is also different. Ordinary putty dries to 1 - 3 days, waterproof putty to 1 week. The season is different, the drying time is also different, generally in summer in 2-3 days, winter if need 5-7 days, if encounter rainy weather, then the time will be prolonged, the specific situation also depends on the entire home decoration environment.

　　以上4種方法是區(qū)分膩子是否完全干燥的方法，所以我們需要特別注意這一環(huán)節(jié)，以便我們可以進(jìn)行下一步的工作。以上每一個都是使用較多的，我們根據(jù)自己的情況來選擇。

　　The above four methods are to distinguish whether the putty is completely dry or not, so we need to pay special attention to this link so that we can proceed with the next step. Each of the above is used more, we choose according to our own situation.
