墻面裝修少不了膩子粉，膩子粉可以保護外墻，也可以防水，所以在裝修的時候使用比較廣泛。膩子粉也分成兩種，一種是內墻膩子粉，另一種就是外墻膩子粉。這兩種膩子粉首先是成分不同，外墻膩子粉多以白水泥為主，內墻膩子粉國內主要以老粉、滑石粉為主。其次是耐水性不同，外墻膩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膠粉含量不同。那么外墻防水膩子可以用在內墻嗎？

　　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、內墻膩子粉

　　1、 Interior wall putty powder

　　1、內墻膩子粉采用高分子聚合物、甲基纖維醚等原料精制而成的單組分內墻專用膩子粉，具有良好的堅固性，粘接強度及良好的防水能力等特點，適合于高檔會館、會議核心及需要預防外墻面滲水影響的高檔場所等場所。

　　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、特點：使用內墻膩子粉纖維的墻面可用水清洗、不掉灰、不脫落、輕微撞擊不留痕跡。3、使用方法：將膩子粉加水攪拌一會成膏狀膩子后靜置，然后即可批刮上墻，一般刮兩遍，第2遍刮得時候要等第墻面干了才能刮。干燥后應及時用砂紙打磨，整平后清除整個墻面灰塵，稍干即可施涂乳膠漆。

　　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：常態或高溫分解時均無毒，化學安定性高。

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

　　二、外墻膩子粉

　　2、 Exterior wall putty powder

　　1、外墻膩子粉采用進口高分子聚合物可再分散膠粉，摻甲基纖維醚、改性淀粉醚、抗裂纖維為膩子粉混合料重量比的（3％）、等原料精制而成的室外一等膩子粉，對墻體的微裂有較強抵抗力，具有良好的額粘度，抗滲能力，可靠性，自身不收縮等特點。

　　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、特點：質量合格膩子粉具有良好的抗裂性，大大節約了整體強面的保養成本。

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

　　3、使用方法：外墻膩子粉加水攪拌成膏狀靜置一會，然后即可批抹上墻，一般厚度不宜超過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、注意事項：由于外墻膩子粉具有很好的保水能力，能夠減緩凝固，避免早期干燥收縮裂紋的產生。因此施工中應注意，一定要等干透后才能進行第2層作業。施工環境溫度不能地于5度，陰雨天不能施工。三、外墻防水膩子可以用在內墻嗎

　　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

　　專業的角度上，外墻防水膩子粉用在內墻上非常好不要，外墻膩子粉柔韌性不足，做內墻使用容易開裂，而且外墻膩子粉都比較粗，做內墻使用裝修效果比較差。當然，也不是完全不可以，只是相對來說成本較高，刷完漆出來的裝飾效果不如室內膩子的好，

　　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,

　　環保度來講也不如室內膩子，要是用在室內的話可以買耐水膩子就可以了。

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

　　四、外墻膩子粉和內墻膩子粉的區別

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

　　1、成分不同，外墻膩子粉多以白水泥為主，內墻膩子粉國內主要以老粉、滑石粉為主。

　　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，外墻膩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膠粉含量不同。

　　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、外墻膩子粉水泥含量高所以一般堿性較強。

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

　　4、內墻膩子粉相對細膩些，滿足內墻施工特點；打磨性也比外墻膩子粉好點。

　　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、外墻膩子粉更加堅固；施工相對難點。

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

　　6、價格普遍外用的貴些。

　　6. Prices are generally higher for external use.

　　五、外墻膩子粉的作用

　　5、 The function of exterior wall putty powder

　　外墻膩子粉作為家庭裝修中一種重要的建筑配料，它涂抹于建筑墻面于外表涂料中間，起著“里應外合”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".

　　外墻膩子粉能有效地解決墻面的平整度問題，倘若墻面不夠平整，涂上一些膩子粉會填補墻面基層的孔隙，使前面外觀看起來更加美觀，勻稱大方。膩子粉材料具有光滑性，有一定的吸水能力和防潮能力。外墻膩子粉還可以增強墻壁表面的花紋和質感，使墻體表面風格迥異，色彩淳樸大方。

　　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.
