At present, the main components of putty powder are talc powder and glue, which are divided into interior wall putty and exterior wall putty. The exterior wall putty should resist wind and sun, so it has large glue, high strength and slightly low environmental protection index. The comprehensive index of interior wall putty is good, healthy and environmental protection, so the interior wall is not used externally and the exterior wall is not used internally. During construction, it is still necessary to apply a layer of interface agent on the base course to seal the base course and improve the adhesion of the wall so that the putty can be better bonded to the base surface. Today, let's talk about the performance of the main function of putty powder?

一、抗開裂作用

1、 Anti cracking effect

裝修的房子常見的問題就是墻面開裂，甚至在還沒交房的時候就已經有墻面開裂的情況，好的膩子粉抗自裂是一項重要的產品指標，按照墻面膩子標準施工工藝施工，可以防止墻面開裂情況。質量不達標的膩子粉，會出現細裂紋，形式烏龜背，故稱“龜裂紋”，龜裂紋常引起涂層的起殼、脫落，影響墻面美觀。

The common problem of decorated houses is wall cracking. Even before the house is delivered, there is wall cracking. Good putty powder anti self cracking is an important product index. Construction according to the standard construction process of wall putty can prevent wall cracking. The putty powder with substandard quality will have fine cracks in the form of turtle back, so it is called "turtle crack". Turtle crack often causes the shell and fall off of the coating and affects the beauty of the wall.

二、平整美觀

2、 Flat and beautiful

在裝修過程中，用戶要求墻面不僅是平整的，還要求光滑細膩。特別部分墻漆對墻面的細膩度要求更高。要提高光滑度，需要改良膩子基層的性能。

In the process of decoration, users require that the wall is not only flat, but also smooth and delicate. In particular, some wall paints have higher requirements for the fineness of the wall. To improve the smoothness, the performance of putty base needs to be improved.

三、填平作用

3、 Filling effect

平整是對墻面基本的要求，通常墻面平整度用靠尺和水平儀檢測，平整度≤3mm。因而填充性是膩子的一項基本功能。在施工中不平整的情況比比皆是。例如：水泥砂漿面的凹凸不平，部分墻面的不平整，或頂棚在燈光下普遍的波浪起伏狀，影響建筑物的美觀。

Flatness is the basic requirement for the wall. Generally, the flatness of the wall is detected with guiding rule and level, and the flatness is ≤ 3mm. Therefore, filling is a basic function of putty. Uneven conditions can be found everywhere in construction. For example, the uneven cement mortar surface, the unevenness of some walls, or the general undulation of the ceiling under the light affect the beauty of the building.

如果水泥墻面或者墻面有坑洞的情況，建議使用抗裂粉刷基底先找平，抗裂粉刷基底找平墻面不收縮(大多數膩子粉進行坑、洞找平，待墻面干燥后，還會出現凹凸不平的現象，是因為膩子粉有收縮性導致)，再用耐水防潮膩子精細找平即可。

If there are pits on the cement wall or the wall, it is recommended to use the anti crack paint base for leveling first, and the anti crack paint base for leveling the wall does not shrink (most putty powders are used for pit and hole leveling, and there will be irregularities after the wall is dry, which is caused by the shrinkage of the putty powder), and then use the water-resistant and moisture-proof putty for fine leveling.
