粉刷石膏作為新型綠色環保建筑內墻抹灰找平材料，具有良好的和易性、保水性、粘結性能好、漿料水化充分，與基層材料粘結牢固等特點，目前在建筑內墻抹灰中應用越來越廣泛，從而針對粉刷石膏相關的問題疑問增加如：粉刷石膏怎么用？粉刷石膏刮幾遍？粉刷石膏一般抹多厚？等等！針對這些問題來一一為大家解答疑問。

Gypsum plastering, as a new type of green and environmentally friendly building interior wall plastering and leveling material, has the characteristics of good workability, water retention, good bonding performance, sufficient hydration of the slurry, and strong bonding with the base material. Currently, it is increasingly widely used in the plastering of building interior walls, which increases questions related to gypsum plastering, such as how to use gypsum plastering? How many times should I apply plaster and scrape it? How thick is gypsum usually applied for plastering? Wait! Let's answer each of these questions one by one.

粉刷石膏使用范圍

Scope of application for plastering gypsum

粉刷石膏主要用于建筑內墻混凝土、加氣混凝土、磚混砂漿墻面和頂棚抹灰找平。

Gypsum plastering is mainly used for leveling the interior walls of buildings with concrete, aerated concrete, brick and mortar walls, and ceilings.

粉刷石膏使用步驟方法

Steps and methods for using plaster for plastering

基層處理：為保證粉刷石膏與基層表面粘結牢固，須用掃帚、鋼絲刷等工具將基層浮灰、雜物清理干凈，并將基層表面凹凸部位修補踢平。保證基層干凈、平整和堅實，以保證抹灰后不出現空鼓、脫落等現象。如果基層疏松或者平滑，需用按標準稀釋的滲透界面劑進行滲透密實界面處理；如基層過于干燥，可適當用水對墻面基層進行濕潤，但不可有明水。

Grassroots treatment: To ensure that the plaster is firmly bonded to the surface of the base layer, it is necessary to use tools such as brooms and wire brushes to clean the floating ash and debris on the base layer, and repair and level the uneven areas on the surface of the base layer. Ensure that the base layer is clean, flat, and solid to prevent hollowing, peeling, and other phenomena after plastering. If the base layer is loose or smooth, it is necessary to use a penetration interface agent diluted according to the standard for penetration compaction interface treatment; If the base layer is too dry, the wall base layer can be moistened with water appropriately, but there should be no open water.

調配粉刷石膏漿料：按合適的粉水比例（粉刷石膏粉料︰水=4︰1，實際粉水比以實際施工稠度為準），先將水倒入攪拌桶中，然后再倒入粉刷石膏粉料，采用電動攪拌器攪拌均勻無粉粒粉狀，是粉刷石膏漿料達到所需的稠度，靜置5分鐘有后再次進行攪拌均勻后方可批刮施工。

Preparation of plastering gypsum slurry: According to the appropriate powder water ratio (plastering gypsum powder: water=4:1, the actual powder water ratio is based on the actual construction consistency), first pour water into the mixing bucket, and then pour the plastering gypsum powder. Use an electric mixer to mix evenly without powder particles, until the plastering gypsum slurry reaches the required consistency. Let it stand for 5 minutes, and then mix evenly again before batch scraping construction.

粉刷石膏抹灰找平：粉刷石膏每次抹灰厚度控制在5mm左右，如果需要找平厚度較大，須嚴格分層次抹灰找平。根據抹灰部位確定抹灰順序路線。可按先頂棚,后墻面,先上后下(如果工人操作順手,從下往上抹也可),從門口一側開始,另一側退出,整個墻面連續作業。混凝土頂棚可以用粉刷石膏一次抹灰成功。如平整度相差太大,可先抹底子灰(薄薄粗抹一遍粉刷石膏漿),然后再抹二遍壓光。二遍抹灰找平施工需上一層粉刷石膏層終凝后再進行，用刮尺沿墻面垂直水平方向緊貼灰餅進行批刮找平，直至找平為止，用木抹子搓毛壓實。

Gypsum plastering and leveling: The thickness of gypsum plastering should be controlled at around 5mm each time. If a larger thickness needs to be leveled, it must be strictly leveled in layers. Determine the plastering sequence and route based on the plastering location. You can start with the ceiling, then the wall, and start with the top and then the bottom (if the workers are comfortable with the operation, they can also wipe from bottom to top), starting from one side of the door and exiting from the other side, and the entire wall can be operated continuously. The concrete ceiling can be successfully plastered with plaster in one go. If the difference in flatness is too large, you can first apply the base plaster (thin and coarse coat with gypsum slurry), and then apply two coats of calendering. The second layer of plastering and leveling construction needs to be carried out after the final setting of the previous layer of plaster. Use a scraper to closely adhere to the plaster cake in the vertical and horizontal direction of the wall surface for batch scraping and leveling until it is level. Use a wooden trowel to rub and compact.

粉刷石膏使用注意

Precautions for using plaster for plastering

1.粉刷石膏施工使用環境溫度應在5℃至35℃之間，固化過程溫度不低于0℃；

1. The ambient temperature for plastering gypsum construction should be between 5 ℃ and 35 ℃, and the curing process temperature should not be lower than 0 ℃;

2.注意調配粉刷石膏漿料的粉水比，加水過多不易上墻且已形成水波浪，加水量過少不易施工且不易上平收光；

2. Pay attention to the powder to water ratio of the gypsum slurry for plastering. Adding too much water is not easy to apply to the wall and has formed water waves. Adding too little water is not easy to apply and is not easy to apply and smooth;

2.粉刷石膏施工基層不應有明水，不宜太潮濕；

2. The base layer of gypsum plastering construction should not have exposed water and should not be too damp;

3.調配好的粉刷石膏漿料應在初凝前使用，一般在1小時左右；

3. The prepared gypsum slurry for plastering should be used before initial setting, usually around 1 hour;

4.拌合粉刷石膏的工具用完應及時清洗。

4. The tools for mixing and painting gypsum should be cleaned promptly after use.
