墙面装修少不了腻子粉，腻子粉可以保护外墙，也可以防水，所以在装修的时候使用比较广泛。腻子粉也分成两种，一种是内墙腻子粉，另一种就是外墙腻子粉。这两种腻子粉首先是成分不同，外墙腻子粉多以白水泥为主，内墙腻子粉国内主要以老粉、滑石粉为主。其次是耐水性不同，外墙腻子粉干燥后有非常好的耐水性能，主要是水泥含量不同或者胶粉含量不同。那么外墙防水腻子可以用在内墙吗？

　　Wall decoration cannot do without putty powder. Putty powder can protect the exterior wall and also prevent waterproofing, so it is widely used in decoration. Putty powder is also divided into two types, one is interior wall putty powder, and the other is exterior wall putty powder. These two types of putty powders are mainly composed of different ingredients. For exterior wall putty powders, white cement is the main ingredient, while for interior wall putty powders, aged powder and talcum powder are the main ingredients in China. Secondly, the water resistance is different. The exterior wall putty powder has very good water resistance after drying, mainly due to different cement or rubber powder contents. Can exterior waterproof putty be used for interior walls?

　　一、内墙腻子粉

　　1、 Interior wall putty powder

　　1、内墙腻子粉采用高分子聚合物、甲基纤维醚等原料精制而成的单组分内墙专用腻子粉，具有良好的坚固性，粘接强度及良好的防水能力等特点，适合于高档会馆、会议核心及需要预防外墙面渗水影响的高档场所等场所。

　　1. The interior wall putty powder is a single component interior wall specific putty powder refined from high molecular weight polymers, methyl fiber ether and other raw materials. It has good durability, adhesive strength and good waterproof ability, and is suitable for high-end clubs, conference centers and high-end places that need to prevent the impact of external wall water leakage.

　　2、特点：使用内墙腻子粉纤维的墙面可用水清洗、不掉灰、不脱落、轻微撞击不留痕迹。3、使用方法：将腻子粉加水搅拌一会成膏状腻子后静置，然后即可批刮上墙，一般刮两遍，第2遍刮得时候要等第墙面干了才能刮。干燥后应及时用砂纸打磨，整平后清除整个墙面灰尘，稍干即可施涂乳胶漆。

　　2. Features: The wall surface using interior putty powder fiber can be cleaned with water, does not shed dust, does not fall off, and leaves no traces after slight impact. 3. Usage: Mix the putty powder with water for a while to form a paste like putty, then let it stand. Then, it can be scraped onto the wall, usually twice. When scraping the second time, wait for the wall to dry before scraping. After drying, it should be sanded with sandpaper in a timely manner. After leveling, the dust on the entire wall should be removed, and latex paint can be applied when it is slightly dry.

　　4、安全安定性：常态或高温分解时均无毒，化学安定性高。

　　4. Safety and stability: It is non-toxic during normal or high-temperature decomposition, and has high chemical stability.

　　二、外墙腻子粉

　　2、 Exterior wall putty powder

　　1、外墙腻子粉采用进口高分子聚合物可再分散胶粉，掺甲基纤维醚、改性淀粉醚、抗裂纤维为腻子粉混合料重量比的（3％）、等原料精制而成的室外一等腻子粉，对墙体的微裂有较强抵抗力，具有良好的额粘度，抗渗能力，可靠性，自身不收缩等特点。

　　1. The exterior wall putty powder is made of imported high molecular weight polymer redispersible rubber powder, mixed with methyl fiber ether, modified starch ether, and crack resistant fiber as the weight ratio of the putty powder mixture (3%), and other raw materials refined into outdoor first-class putty powder. It has strong resistance to micro cracks in the wall, good viscosity, impermeability, reliability, and does not shrink on its own.

　　2、特点：质量合格腻子粉具有良好的抗裂性，大大节约了整体强面的保养成本。

　　2. Features: Qualified putty powder has good crack resistance, greatly saving the maintenance cost of the overall strong surface.

　　3、使用方法：外墙腻子粉加水搅拌成膏状静置一会，然后即可批抹上墙，一般厚度不宜超过2－3mm，按不同要求可分一至三遍批抹，增加其厚度。

　　3. Usage: Mix the exterior wall putty powder with water to form a paste and let it sit for a while. Then, apply it to the wall in batches. Generally, the thickness should not exceed 2-3mm. Depending on different requirements, it can be applied in batches of one to three times to increase its thickness.

　　4、注意事项：由于外墙腻子粉具有很好的保水能力，能够减缓凝固，避免早期干燥收缩裂纹的产生。因此施工中应注意，一定要等干透后才能进行第2层作业。施工环境温度不能地于5度，阴雨天不能施工。三、外墙防水腻子可以用在内墙吗

　　4. Attention: Due to the excellent water retention ability of exterior wall putty powder, it can slow down solidification and avoid the occurrence of early drying shrinkage cracks. Therefore, during construction, it should be noted that the second layer of work can only be carried out after it has dried completely. The construction environment temperature cannot be above 5 degrees Celsius, and construction cannot be carried out on rainy days. 3、 Can exterior waterproof putty be used for interior walls

　　专业的角度上，外墙防水腻子粉用在内墙上最好不要，外墙腻子粉柔韧性不足，做内墙使用容易开裂，而且外墙腻子粉都比较粗，做内墙使用装修效果比较差。当然，也不是完全不可以，只是相对来说成本较高，刷完漆出来的装饰效果不如室内腻子的好，

　　From a professional perspective, it is best not to use exterior wall waterproof putty powder for interior walls. The flexibility of exterior wall putty powder is insufficient, and it is easy to crack when used for interior walls. Moreover, the exterior wall putty powder is relatively coarse, which results in poor decoration effects when used for interior walls. Of course, it's not entirely impossible, but relatively speaking, the cost is higher and the decorative effect after painting is not as good as indoor putty,

　　环保度来讲也不如室内腻子，要是用在室内的话可以买耐水腻子就可以了。

　　In terms of environmental friendliness, it is not as good as indoor putty. If used indoors, you can buy water-resistant putty.

　　四、外墙腻子粉和内墙腻子粉的区别

　　4、 The difference between exterior wall putty powder and interior wall putty powder

　　1、成分不同，外墙腻子粉多以白水泥为主，内墙腻子粉国内主要以老粉、滑石粉为主。

　　1. The composition is different. The exterior wall putty powder is mainly composed of white cement, while the interior wall putty powder in China is mainly composed of old powder and talcum powder.

　　2、耐水性不同，外墙腻子粉干燥后有非常好的耐水性能，主要是水泥含量不同或者胶粉含量不同。

　　2. Different water resistance, exterior wall putty powder has very good water resistance after drying, mainly due to different cement content or rubber powder content.

　　3、外墙腻子粉水泥含量高所以一般碱性较强。

　　3. Exterior wall putty powder has a high cement content, so it generally has strong alkalinity.

　　4、内墙腻子粉相对细腻些，满足内墙施工特点；打磨性也比外墙腻子粉好点。

　　4. The interior wall putty powder is relatively delicate, meeting the characteristics of interior wall construction; The polishing performance is also better than that of exterior wall putty powder.

　　5、外墙腻子粉更加坚固；施工相对难点。

　　5. Exterior wall putty powder is more sturdy; Construction is relatively difficult.

　　6、价格普遍外用的贵些。

　　6. Prices are generally higher for external use.

　　五、外墙腻子粉的作用

　　5、 The function of exterior wall putty powder

　　外墙腻子粉作为家庭装修中一种重要的建筑配料，它涂抹于建筑墙面于外表涂料中间，起着“里应外合”的媒介作用。

　　Exterior wall putty powder, as an important building ingredient in home decoration, is applied to the middle of building walls and exterior coatings, playing a medium role of "matching inside and outside".

　　外墙腻子粉能有效地解决墙面的平整度问题，倘若墙面不够平整，涂上一些腻子粉会填补墙面基层的孔隙，使前面外观看起来更加美观，匀称大方。腻子粉材料具有光滑性，有一定的吸水能力和防潮能力。外墙腻子粉还可以增强墙壁表面的花纹和质感，使墙体表面风格迥异，色彩淳朴大方。

　　Exterior wall putty powder can effectively solve the problem of wall flatness. If the wall surface is not flat enough, applying some putty powder will fill the pores in the base layer of the wall, making it look more beautiful and symmetrical when viewed from the front. Putty powder material has smoothness, certain water absorption and moisture resistance. Exterior wall putty powder can also enhance the pattern and texture of the wall surface, making the wall surface style different and the color simple and elegant.
