房子装修完之后，入住几年，通常会出现墙面开裂的情况，墙面脱落等一些问题，如果售后质保期过了之后，就得需要自己去处理或者请工人来帮忙修复一下，如果是小范围的问题，我们完全是可以自己来处理的，其实补墙是一份很简单的工作。下面来讲讲石膏粉补墙方法以及选购方法。

After the decoration of the house, we usually have some problems, such as wall cracking, wall peeling, etc. After the after-sales warranty period expires, we have to deal with it or ask workers to help repair it. If it is a small problem, we can completely deal with it by ourselves. In fact, repairing the wall is a very simple job. Next, we will talk about the method of plastering and purchasing.

1、在补墙时我们一定要选择硬度比较好的济南石膏粉，水与石膏粉的比例为28:100，这样就能直接按照按比例直进行调和。在调和时一定先要加水，再加石膏粉，若是反过来的话就很难把两者能搅拌均匀，并且石膏粉与水搅拌的越均匀，制作出的石膏就会越牢固。

1. When repairing the wall, we must choose Jinan gypsum powder with good hardness. The ratio of water to gypsum powder is 28:100, so that we can directly mix according to the ratio. When mixing, water must be added first, and then gypsum powder. If it is the opposite, it is difficult to mix the two evenly. The more evenly the gypsum powder and water are mixed, the stronger the gypsum will be.

2、石膏凝固时间与加水量关系很大，其次就是搅拌时间，温度和湿度等一方面。水加的太多那凝固时间就越长，那也就会不会牢固，反而凝固时间越短，石膏就会更加牢固。

2. The setting time of gypsum is closely related to the amount of water added, followed by the mixing time, temperature and humidity. If too much water is added, the longer the setting time is, the less firm it will be. On the contrary, the shorter the setting time is, the stronger the gypsum will be.

3、添加乳白胶以后，石膏就会变得更加牢固，表面上还会显得非常细腻光滑，但石膏凝固时间就会很长。把石膏填补在墙体中的裂缝中，就要将裂缝填满，这样才能适当的添加一些碎石，瓦砾当作填充物。填补完成以后再使用刮刀将石膏上的表面层磨平这样才能和整个墙面融为一体，这样看上去非常的美观。

3. After the addition of milk white glue, the gypsum will become more firm, and the surface will appear very fine and smooth, but the gypsum solidification time will be very long. When gypsum is filled in the cracks in the wall, it is necessary to fill the cracks, so that some gravel can be properly added, and the rubble can be used as filler. After filling, use a scraper to smooth the surface layer on the plaster so that it can be integrated with the whole wall, which looks very beautiful.

此外我们在购买石膏粉时一定要寻选择硬度较好的，特别是A级别或特级粉，这样的石膏粉白而细腻非常好。在挑选时先要看下石膏粉的颜色，主要颜色分别是灰色，黄色和白色。而灰色的石膏粉一般都使用到大部分的建筑上面，从而我们可以认真细察石膏粉在浸水以后是否还能发现里面是否还会黑色小颗粒杂质，如果有这种石膏比较脆，价格也比较便宜。

In addition, when purchasing gypsum powder, we must look for and choose the ones with better hardness, especially grade A or super grade powder. Such gypsum is very white and delicate. When selecting, first look at the color of gypsum powder. The main colors are gray, yellow and white. The gray gypsum powder is generally used in most buildings, so we can carefully examine whether the gypsum powder can still find black and small particles in it after being soaked in water. If there is this kind of gypsum, it is brittle and cheap.

像黄色系列的石膏，大部分都使用到制模，雕塑上，黄色石膏粉它的材料非常坚硬，而且制作出的细目作品也非常精美。您对产品有需求就来我们网站咨询了解吧！
