装修墙面就像给房子 “化妆”，而腻子粉便是打造完美底妆的关键。刮腻子看似简单，实则藏着大学问，刮几遍、每遍间隔多久，这些细节直接影响墙面的平整度、光滑度和耐用性。掌握腻子粉刮涂的时间与遍数密码，才能让墙面颜值与品质双在线。

　　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.

　　腻子粉的刮涂遍数并非固定不变，而是要根据墙面的具体情况 “量体裁衣”。对于新砌的墙面或平整度较好的基层，一般刮两遍腻子即可。第一遍腻子主要起到填补墙面细小裂缝、凹凸不平处的作用，就像给墙面打个 “粗底”，让墙面变得基本平整；第二遍腻子则是在第一遍的基础上进一步找平，细化墙面的平整度和光滑度，为后续的乳胶漆涂刷或贴壁纸做好准备。而如果墙面存在较大的凹陷、孔洞，或是旧房翻新时墙面基层状况较差，就需要刮三遍腻子。多出来的这一遍，着重处理那些顽固的不平整区域，通过多次填补、刮平，确保墙面达到理想的平整度。

　　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.

　　每遍腻子之间的间隔时间也十分讲究，它就像等待 “化学反应” 的过程，时间过短，腻子未干透就刮下一遍，容易导致墙面起皮、开裂；时间过长，干透的腻子表面过于坚硬，又会增加打磨难度。一般来说，在正常的室内环境温度（20℃左右）和湿度条件下，第一遍腻子刮完后，需要等待 1 - 2 天，让腻子充分干燥。判断腻子是否干透，可以用手触摸墙面，若感觉干燥、坚硬，没有潮湿感，且指甲轻划墙面不会留下明显痕迹，就说明腻子已基本干燥，可以进行下一遍刮涂。如果室内环境潮湿，腻子干燥速度会明显变慢，此时需要适当延长间隔时间，甚至可以借助风扇、除湿机等设备加快干燥进程；而在干燥炎热的环境中，腻子干燥速度快，但也容易出现表面干裂的情况，这就需要在刮涂时控制好腻子的厚度，并适当喷水保湿，保证腻子均匀干燥。

　　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.

　　除了时间和遍数，刮腻子的施工工艺同样会影响最终效果。刮涂时要使用合适的工具，如刮板，确保用力均匀，避免出现厚薄不均的现象。每一遍腻子刮涂的方向最好相互垂直，这样可以更有效地发现和填补墙面的不平整处。刮完腻子后，还需要进行打磨工序，一般在最后一遍腻子干燥后 1 - 2 天进行。打磨时要选用合适目数的砂纸，从粗砂纸到细砂纸逐步打磨，将墙面打磨得光滑平整，同时注意避免过度打磨，损伤腻子层。

　　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.

　　刮腻子作为墙面装修的重要环节，每一遍的涂抹、每一刻的等待都不容忽视。根据墙面状况确定刮涂遍数，严格把控每遍腻子的间隔时间，再辅以规范的施工工艺，才能让墙面从粗糙的基层蜕变为细腻平滑的完美基底，为整个空间的颜值打下坚实基础，让家的 “面子” 更有质感。

　　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.
