粉刷石膏作为新型绿色环保建筑内墙抹灰找平材料，具有良好的和易性、保水性、粘结性能好、浆料水化充分，与基层材料粘结牢固等特点，目前在建筑内墙抹灰中应用越来越广泛，从而针对粉刷石膏相关的问题疑问增加如：粉刷石膏怎么用？粉刷石膏刮几遍？粉刷石膏一般抹多厚？等等！针对这些问题来一一为大家解答疑问。

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.

粉刷石膏使用范围

Scope of application for plastering gypsum

粉刷石膏主要用于建筑内墙混凝土、加气混凝土、砖混砂浆墙面和顶棚抹灰找平。

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

粉刷石膏使用步骤方法

Steps and methods for using plaster for plastering

基层处理：为保证粉刷石膏与基层表面粘结牢固，须用扫帚、钢丝刷等工具将基层浮灰、杂物清理干净，并将基层表面凹凸部位修补踢平。保证基层干净、平整和坚实，以保证抹灰后不出现空鼓、脱落等现象。如果基层疏松或者平滑，需用按标准稀释的渗透界面剂进行渗透密实界面处理；如基层过于干燥，可适当用水对墙面基层进行湿润，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.

调配粉刷石膏浆料：按合适的粉水比例（粉刷石膏粉料︰水=4︰1，实际粉水比以实际施工稠度为准），先将水倒入搅拌桶中，然后再倒入粉刷石膏粉料，采用电动搅拌器搅拌均匀无粉粒粉状，是粉刷石膏浆料达到所需的稠度，静置5分钟有后再次进行搅拌均匀后方可批刮施工。

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，如果需要找平厚度较大，须严格分层次抹灰找平。根据抹灰部位确定抹灰顺序路线。可按先顶棚,后墙面,先上后下(如果工人操作顺手,从下往上抹也可),从门口一侧开始,另一侧退出,整个墙面连续作业。混凝土顶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浆),然后再抹二遍压光。二遍抹灰找平施工需上一层粉刷石膏层终凝后再进行，用刮尺沿墙面垂直水平方向紧贴灰饼进行批刮找平，直至找平为止，用木抹子搓毛压实。

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.粉刷石膏施工使用环境温度应在5℃至35℃之间，固化过程温度不低于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.注意调配粉刷石膏浆料的粉水比，加水过多不易上墙且已形成水波浪，加水量过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.粉刷石膏施工基层不应有明水，不宜太潮湿；

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

3.调配好的粉刷石膏浆料应在初凝前使用，一般在1小时左右；

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应及时清洗。

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