装修师傅一提“找平”就抱出一袋白粉，很多业主根本分不清那是腻子还是石膏粉。其实在家装里，石膏粉是墙面基层的“骨架”：墙面落差超过5mm，建议先用它找平，再上腻子；石膏板接缝、吊顶钉眼、旧墙开槽，也得靠它封口防裂。

When the decorator mentions "leveling", he immediately carries out a bag of white powder, and many homeowners cannot distinguish whether it is putty or gypsum powder. In fact, in home decoration, gypsum powder is the "skeleton" of the wall base layer: if the wall drop exceeds 5mm, it must be leveled first and then putty must be applied; Gypsum board joints, ceiling nail holes, and old wall slotting also need to be sealed and crack resistant with it.

选的时候记住三句话：

Remember three sentences when choosing:

大面积找平用粉刷石膏，颗粒稍粗、强度够，单次可批2–5mm，别拿它当面漆基层。

Use plastering gypsum for large-scale leveling, with slightly coarse particles and sufficient strength. Batch size can be 2-5mm per time. Do not use it to paint the base layer on the surface.

补缝补洞用嵌缝石膏，收缩小、柔韧性好，石膏板拼缝和线槽填它，干后贴一层网格带，基本不会裂。

Jointing gypsum is used for repairing seams and holes, with small shrinkage and good flexibility. It is used to fill gypsum board joints and cable troughs, and after drying, a layer of mesh tape is applied, which is basically not cracked.

别图白度买单，白得发亮的往往加了增白剂，和强度没关系；抓一把捻开，细腻无结块、浅灰或奶白色才正常。

Don't pay for whiteness, as bright white often comes with whitening agents, which have nothing to do with strength; Take a handful and twist it open. It should be delicate without clumping, light gray or milky white to be normal.

施工上也有两个容易翻车的点：搅拌按说明书加水，拌完静置几分钟再用，一次别调太多，石膏凝结快，剩料半小时就废；批刮单次别超2cm，太厚一定分层做，没干透千万别抢工期刮腻子。济南春秋干燥、冬夏温差大，尽量选本地适配配方的产品，抗冻抗裂表现更稳。

There are also two points that are prone to tipping during construction: add water according to the instructions for mixing, let it sit for a few minutes after mixing, and do not mix too much at once. Gypsum sets quickly and the remaining material will be discarded in half an hour; Do not exceed 2cm in a single batch of scraping. If it is too thick, it must be done in layers. If it is not completely dry, do not rush the deadline to apply putty. Jinan is dry in spring and autumn, and there is a large temperature difference between winter and summer. It is recommended to choose products with locally adapted formulas for more stable frost resistance and crack resistance.
