1、 What is the difference between white powder and putty powder

很多人不知道大白粉和腻子粉的区别是什么，严格来说，大白粉就是腻子粉的一种，目前大白粉已经被淘汰了，因为有相关的规定，所有建筑施工都不能再用大白粉来批腻子了。

Many people don't know the difference between big white powder and putty powder. Strictly speaking, big white powder is a kind of putty powder. At present, big white powder has been eliminated. Because there are relevant regulations, big white powder can't be used for putty in all building construction.

1、大白粉

1. Big white powder

大白粉是一种化学粘合剂，易溶于水，以前被广泛的用于墙面和顶棚的修复。使用这种产品也挺不错的，不会出现掉色的情况，但是特别怕水，如果墙面长期处于潮湿的环境中，轻轻一刮就会大片大片的脱落，现在基本已经没有人用了。

White powder is a kind of chemical adhesive, which is easy to dissolve in water. It was previously widely used in the repair of walls and ceilings. It's also very good to use this product. It won't lose color, but it's especially afraid of water. If the wall is in a humid environment for a long time, large pieces of it will fall off with a gentle scraping. Now it's almost no longer used.

2、腻子粉

2. Putty powder

腻子粉是用少量的漆料作为基材，加入大量的填料和颜料调制而成的，颜色的种类比较丰富，用得比较多的有红色、黑色以及白色等等，填料的材质主要有重质碳酸钙、羧甲基纤维素钠、双飞粉、预糊化淀粉、以及滑石粉等等，非常适合用于填补墙体表面有局部凹陷的地方。

Putty powder is prepared by using a small amount of paint as the base material and adding a large amount of fillers and pigments. It has a rich variety of colors, such as red, black and white. The filler materials mainly include heavy calcium carbonate, sodium carboxymethyl cellulose, Shuangfei powder, pregelatinized starch, talc powder, etc., which are very suitable for filling local depressions on the wall surface.

腻子粉的透气性非常好，即使处于潮湿的环境中也不会像大白粉那样出现掉粉的现象。刮腻子粉对施工的要求比较高，如果技术高的话，基本不会出现空鼓、开裂以及起皮等现象。

The air permeability of putty powder is very good. Even in a humid environment, there will be no powder dropping like big white powder. Puttying powder has high requirements for construction. If the technology is high, there will be no hollowing, cracking and peeling.

二、腻子粉该怎么用

2、 How to use putty powder

1、刮腻子粉前应该确保墙体坚实，墙面干净平整，没有颗粒状的脏东西，更不能有水，使腻子粉可以更好的吸附在基层墙体上。

1. Before applying putty powder, ensure that the wall is solid, clean and flat, without granular dirt and water, so that the putty powder can be better adsorbed on the base wall.

2、如果碰到基层墙体非常干燥的，要先将墙体打湿，然后用防水性能好的胶水进行封底，才能进行刮腻子粉的步骤。

2. If the base wall is very dry, wet the wall first, then seal the bottom with glue with good waterproof performance, and then carry out the step of applying putty powder.

3、如果是刚刚抹完会的水泥墙，要过完养护期以后才能进行刮腻子粉的步骤。

3. If the cement wall has just been plastered, the putty powder can only be applied after the curing period.

4、调腻子粉要严格按照1:0.5的比例，搅拌均匀后需要放置20分钟，再搅拌一次才可以使用。

4. The putty powder shall be mixed in strict accordance with the ratio of 1:0.5. It shall be placed for 20 minutes after being evenly mixed, and it can be used only after being stirred again.

5、一般刮腻子粉的次数不能太多，两次佳，因为太薄达不到效果，太厚容易出现开裂和脱落的情况。需要特别注意在刷二次腻子粉之前，一定要保证一遍腻子粉已经干透才行。

5. Generally, the number of times to apply putty powder should not be too many. It is better to apply putty powder twice, because it is too thin to achieve the effect, and it is easy to crack and fall off if it is too thick. Special attention shall be paid to ensure that the first coat of putty powder has been completely dried before applying the second coat of putty powder.

6、两遍腻子粉都干了要进行打磨，然后尽快进行装饰墙壁的步骤。

6. When the putty powder is dry for two times, polish it, and then carry out the steps of decorating the wall as soon as possible.
