房子裝修完之后，入住幾年，通常會出現墻面開裂的情況，墻面脫落等一些問題，如果售后質保期過了之后，就得需要自己去處理或者請工人來幫忙修復一下，如果是小范圍的問題，我們完全是可以自己來處理的，其實補墻是一份很簡單的工作。下面來講講石膏粉補墻方法以及選購方法。

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、在補墻時我們一定要選擇硬度比較好的濟南石膏粉，水與石膏粉的比例為28:100，這樣就能直接按照按比例直進行調和。在調和時一定先要加水，再加石膏粉，若是反過來的話就很難把兩者能攪拌均勻，并且石膏粉與水攪拌的越均勻，制作出的石膏就會越牢固。

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、石膏凝固時間與加水量關系很大，其次就是攪拌時間，溫度和濕度等一方面。水加的太多那凝固時間就越長，那也就會不會牢固，反而凝固時間越短，石膏就會更加牢固。

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、添加乳白膠以后，石膏就會變得更加牢固，表面上還會顯得非常細膩光滑，但石膏凝固時間就會很長。把石膏填補在墻體中的裂縫中，就要將裂縫填滿，這樣才能適當的添加一些碎石，瓦礫當作填充物。填補完成以后再使用刮刀將石膏上的表面層磨平這樣才能和整個墻面融為一體，這樣看上去非常的美觀。

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.

此外我們在購買石膏粉時一定要尋選擇硬度較好的，特別是A級別或特級粉，這樣的石膏粉白而細膩非常好。在挑選時先要看下石膏粉的顏色，主要顏色分別是灰色，黃色和白色。而灰色的石膏粉一般都使用到大部分的建筑上面，從而我們可以認真細察石膏粉在浸水以后是否還能發現里面是否還會黑色小顆粒雜質，如果有這種石膏比較脆，價格也比較便宜。

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.

像黃色系列的石膏，大部分都使用到制模，雕塑上，黃色石膏粉它的材料非常堅硬，而且制作出的細目作品也非常精美。您對產品有需求就來我們網站http://m.sjzmx.cn咨詢了解吧！
