內墻膩子粉可以作為外墻涂料嗎？需要注意什么？家居雜壇首先給出到個人觀點就是內墻的膩子粉絕對不能夠用于外墻，無論是用于外墻的膩子還是用于外墻的涂料，都是不合適的，會引起很多的質量問題。為什么不建議把內墻膩子用于外墻涂料呢？個人給出的原因有如下三點，這三點主要就是由于內墻膩子用于外墻所引發的問題。

Can interior wall putty powder be used as exterior wall coating? What should I pay attention to? The first personal opinion given by Home Furnishing ZaTan is that putty powder for interior walls should never be used for exterior walls. Whether it is putty or paint for exterior walls, it is not suitable and can cause many quality problems. Why is it not recommended to use interior wall putty for exterior wall coatings? There are three reasons given by me, mainly due to the problems caused by the use of interior wall putty for exterior walls.

問題①：膩子完成以后的強度過低，無法保證外墻墻面所需要的強度。為什么說內墻的膩子用于外墻涂料時強度很低呢？因為我們內墻膩子本來很對于強度要求不是特別高，它主要就是起到一個打底和找平的作用。但是對于外墻就有一定的強度要求。一般來說，普通的內墻膩子的強度只有外墻膩子的一半左右，所以是絕對不能夠擁有外墻的。

Problem 1: The strength of the putty after completion is too low to ensure the required strength for the exterior wall surface. Why is it said that the putty for interior walls has low strength when used for exterior wall coatings? Because our interior wall putty does not require particularly high strength, it mainly serves as a base and leveling agent. But there are certain strength requirements for the exterior walls. Generally speaking, the strength of ordinary interior wall putty is only about half of that of exterior wall putty, so it is absolutely not enough to have exterior walls.

問題②：會出現起粉的現象。把內墻的膩子用到外墻以后，容易出現的一種問題就是起粉。因為我們內墻膩子的防潮防水性能非常差，而用在外墻以后會與室外的空氣接觸，時間久了，這種膩子就慢慢的與水發生化學反應，最后導致膩子的失效。我們看到的結果就是外墻大面積的掉粉。

Problem 2: There may be a phenomenon of powdering. One common problem when applying putty from the interior walls to the exterior walls is powdering. Because the moisture and waterproof performance of our interior wall putty is very poor, and when used on the exterior wall, it will come into contact with the outdoor air. Over time, this putty will slowly react chemically with water, ultimately leading to the failure of the putty. The result we see is a large area of powder falling off the exterior walls.
