很多人把石膏粉和腻子粉混为一谈——但它们根本是两回事。搞错了轻则多花冤枉钱，重则墙面大面积开裂。

Many people confuse gypsum powder and putty powder - but they are fundamentally different things. Mistakes can result in unnecessary spending, and in severe cases, widespread wall cracking.

核心区别：石膏粉是“打底塑形”，腻子粉是“化妆收尾”

Core difference: Gypsum powder is the "base shaping", while putty powder is the "makeup finishing"

石膏粉颗粒粗、能厚批，是给毛坯墙“打底”的；腻子粉细，只能薄刮（单次≤3mm），是“精修收尾”的。墙面坑洼超过5mm，建议先用石膏粉填坑，再用腻子盖面，顺序绝对不能反。

Gypsum powder particles are coarse and thick, and can be used as a base for rough walls; The putty powder is fine and can only be lightly scraped (single time ≤ 3mm), which is a "finishing touch". Wall potholes exceeding 5mm must be filled with gypsum powder first, and then covered with putty. The order must not be reversed.

选购要点：一分钱一分货

Key points for purchasing: get what you pay for

家装用的袋装石膏粉，20公斤规格，价格从二十来块到六七十都有。建议别碰20元以下的——可能掺了滑石粉或杂质，粘结力差。选择符合GB/T 13079-2006国标的产品，优先品牌如美巢、圣戈班、德高。灰石膏粉适合一般修补，白色石膏粉（A级/特级）质地更细、强度更高，适合精细处理。

Bagged gypsum powder for home decoration, with a specification of 20 kilograms and prices ranging from around 20 yuan to 60-70 yuan. It is recommended not to touch anything below 20 yuan - it may be mixed with talcum powder or impurities, resulting in poor adhesion. Choose products that comply with the GB/T 13079-2006 national standard, with priority given to brands such as Meichao, Saint Gobain, and Degao. Gray gypsum powder is suitable for general repairs, while white gypsum powder (grade A/special grade) has a finer texture and higher strength, making it suitable for fine processing.

施工第一铁律：不加胶水！

The first iron rule of construction: no glue added!

现在的成品石膏粉出厂时胶粉已配好，只加清水搅拌即可。工人要加801胶？那是为了好施工，但环保全毁了，坚决拒绝。发现加了直接换人。

The finished gypsum powder is ready with adhesive powder when it leaves the factory, just add water and stir. Do workers need to add 801 glue? That's for the sake of good construction, but the environmental protection has been completely destroyed, and we firmly refuse. Discovered adding a direct replacement.

一次批多厚？单次不超1cm，高差大得分层

How thick is a batch? Single time not exceeding 1cm, with significant height differences resulting in layering

原则上单次不超过1厘米，太厚容易坠裂。高差超过2厘米，先做冲筋找平，或分层刮、分层养护。

In principle, the thickness should not exceed 1 centimeter at a time, as it is too thick and prone to falling and cracking. If the height difference exceeds 2 centimeters, first perform reinforcement leveling or layer by layer scraping and curing.

厨卫禁用石膏粉

Gypsum powder is prohibited in kitchens and bathrooms

石膏怕水，就算标“耐水”也不行，厨卫只能用水泥砂浆或防水腻子。

Gypsum is afraid of water, even if it is labeled as "water-resistant", it cannot be used. Only cement mortar or waterproof putty can be used for kitchens and bathrooms.
