裝修墻面就像給房子 “化妝”，而膩子粉便是打造完美底妝的關鍵。刮膩子看似簡單，實則藏著大學問，刮幾遍、每遍間隔多久，這些細節直接影響墻面的平整度、光滑度和耐用性。掌握膩子粉刮涂的時間與遍數密碼，才能讓墻面顏值與品質雙在線。

　　Decorating walls is like "putting on makeup" for a house, and putty powder is the key to creating a perfect base. Scraping putty may seem simple, but in reality, there is a big question behind it. How many times should it be scraped and how long should the interval between each pass be? These details directly affect the flatness, smoothness, and durability of the wall. Mastering the password for the time and number of times to apply putty powder is essential for achieving both wall appearance and quality.

　　膩子粉的刮涂遍數并非固定不變，而是要根據墻面的具體情況 “量體裁衣”。對于新砌的墻面或平整度較好的基層，一般刮兩遍膩子即可。第一遍膩子主要起到填補墻面細小裂縫、凹凸不平處的作用，就像給墻面打個 “粗底”，讓墻面變得基本平整；第二遍膩子則是在第一遍的基礎上進一步找平，細化墻面的平整度和光滑度，為后續的乳膠漆涂刷或貼壁紙做好準備。而如果墻面存在較大的凹陷、孔洞，或是舊房翻新時墻面基層狀況較差，就需要刮三遍膩子。多出來的這一遍，著重處理那些頑固的不平整區域，通過多次填補、刮平，確保墻面達到理想的平整度。

　　The number of times putty powder is applied is not fixed, but needs to be tailored according to the specific situation of the wall. For newly built walls or substrates with good flatness, it is generally sufficient to apply two coats of putty. The first layer of putty mainly serves to fill small cracks and uneven areas on the wall, like giving a "rough base" to the wall, making it basically flat; The second layer of putty is further leveled on the basis of the first layer, refining the flatness and smoothness of the wall, and preparing for subsequent latex paint application or wallpaper pasting. If there are significant dents or holes on the wall, or if the condition of the wall base is poor during the renovation of an old house, it is necessary to apply three coats of putty. This extra round focuses on dealing with stubborn and uneven areas, by filling and scraping multiple times to ensure that the wall achieves the desired flatness.

　　每遍膩子之間的間隔時間也十分講究，它就像等待 “化學反應” 的過程，時間過短，膩子未干透就刮下一遍，容易導致墻面起皮、開裂；時間過長，干透的膩子表面過于堅硬，又會增加打磨難度。一般來說，在正常的室內環境溫度（20℃左右）和濕度條件下，第一遍膩子刮完后，需要等待 1 - 2 天，讓膩子充分干燥。判斷膩子是否干透，可以用手觸摸墻面，若感覺干燥、堅硬，沒有潮濕感，且指甲輕劃墻面不會留下明顯痕跡，就說明膩子已基本干燥，可以進行下一遍刮涂。如果室內環境潮濕，膩子干燥速度會明顯變慢，此時需要適當延長間隔時間，甚至可以借助風扇、除濕機等設備加快干燥進程；而在干燥炎熱的環境中，膩子干燥速度快，但也容易出現表面干裂的情況，這就需要在刮涂時控制好膩子的厚度，并適當噴水保濕，保證膩子均勻干燥。

　　The interval time between each layer of putty is also very particular. It is like waiting for a "chemical reaction" process. If the time is too short, scraping off the putty before it dries completely can easily lead to peeling and cracking of the wall surface; If the time is too long, the surface of the dried putty will be too hard, which will increase the difficulty of polishing. Generally speaking, under normal indoor environmental temperature (around 20 ℃) and humidity conditions, after the first coat of putty is applied, it is necessary to wait for 1-2 days for the putty to fully dry. To determine if the putty has dried completely, you can touch the wall surface with your hand. If it feels dry, hard, and without any dampness, and the nail lightly scratches the wall surface without leaving obvious marks, it means that the putty has basically dried and can be applied the next time. If the indoor environment is humid, the drying speed of putty will significantly slow down. At this time, it is necessary to extend the interval time appropriately, and even use equipment such as fans and dehumidifiers to accelerate the drying process; In dry and hot environments, putty dries quickly, but it is also prone to surface cracking. This requires controlling the thickness of the putty during scraping and spraying it with water to ensure even drying.

　　除了時間和遍數，刮膩子的施工工藝同樣會影響最終效果。刮涂時要使用合適的工具，如刮板，確保用力均勻，避免出現厚薄不均的現象。每一遍膩子刮涂的方向最好相互垂直，這樣可以更有效地發現和填補墻面的不平整處。刮完膩子后，還需要進行打磨工序，一般在最后一遍膩子干燥后 1 - 2 天進行。打磨時要選用合適目數的砂紙，從粗砂紙到細砂紙逐步打磨，將墻面打磨得光滑平整，同時注意避免過度打磨，損傷膩子層。

　　In addition to time and number of passes, the construction process of scraping putty will also affect the final effect. When scraping, suitable tools such as scrapers should be used to ensure even force and avoid uneven thickness. It is best to apply putty in a direction perpendicular to each other each time, so as to more effectively detect and fill any unevenness on the wall. After scraping the putty, a polishing process is also required, usually 1-2 days after the last layer of putty dries. When polishing, choose sandpaper with appropriate grit size, gradually polishing from coarse sandpaper to fine sandpaper, to make the wall smooth and flat. At the same time, pay attention to avoiding excessive polishing and damaging the putty layer.

　　刮膩子作為墻面裝修的重要環節，每一遍的涂抹、每一刻的等待都不容忽視。根據墻面狀況確定刮涂遍數，嚴格把控每遍膩子的間隔時間，再輔以規范的施工工藝，才能讓墻面從粗糙的基層蛻變為細膩平滑的完美基底，為整個空間的顏值打下堅實基礎，讓家的 “面子” 更有質感。

　　Scraping putty is an important part of wall decoration, and every application and every moment of waiting cannot be ignored. Determine the number of scraping coats based on the condition of the wall, strictly control the interval between each coat of putty, and use standardized construction techniques to transform the wall from a rough base to a smooth and perfect base, laying a solid foundation for the overall appearance of the space and making the "face" of the home more textured.
