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. 视觉判断。这是基本的一种判断方法,腻子干会议后的颜色是白色的,如果有些地方仍然呈现让恐慌或发送灰色的颜色,证明墙面腻子刷没有彻底干燥。如果墙面完全干燥，则其色彩整体一致。

　　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。腻子完全干燥后，可进行第二次刷腻子。检查基层腻子是否干燥有没有简单可行的方法，你只需用手掌触摸墙面，假如腻子已干燥，手掌与墙面摩擦就会发出“沙沙”声;也可以检查手心，如果沾了很多灰尘，摸起来湿漉漉的感觉就可以断定不干燥了。

　　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.

　　使用砂纸。腻子干燥时，用砂纸轻轻打磨会产生粉尘;如果砂纸研磨;没有灰尘或灰尘很少，那证实墙面腻子还没有彻底干燥，绝对不能进行两次腻子的施工。

　　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. 粗略的时间估计。其实腻子干燥时间基本上可以估算，腻子性质不同，时间也不同。普通腻子干燥至1- 3天，防水腻子至1周。季节不同，干燥时间也不同，一般夏天在2-3天就可以了，冬天假如需要5-7天，假如遇到阴雨天气，那么时间就会拖长，具体情况还视整个家装环境而定。

　　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种方法是区分腻子是否完全干燥的方法，所以我们需要特别注意这一环节，以便我们可以进行下一步的工作。以上每一个都是使用较多的，我们根据自己的情况来选择。

　　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.
