　　Product Introduction

　　干粉抹面砂浆是将水泥、填料、骨料和多种功能性外加剂配制而成。对建筑物和墙体可起保护作用。它可以抵抗风、雨、雪等自然环境对建筑物的侵蚀，并提高建筑物的耐久性产品性能：

　　Dry powder plastering mortar is a mixture of cement, filler, aggregate, and various functional additives. It can provide protection for buildings and walls. It can resist the erosion of natural environments such as wind, rain, and snow on buildings, and improve the durability and product performance of buildings

　　3. Strong firmness, durability, and weather resistance construction technology:

　　1清除墙面的灰尘、污垢、碱膜、砂浆块等附着物，要洒水润湿。对主体结构梁、柱有凸出部位先进行凿出，并确保砂浆厚度，如有个别地厚度较薄处可加设玻璃纤维网格。

　　1. Clean the wall of dust, dirt, alkali film, mortar blocks and other attachments, and sprinkle water to wet them. Chisel out the protruding parts of the main structural beams and columns first, and ensure the thickness of the mortar. If there are individual areas with thinner thickness, glass fiber mesh can be added.

　　2.吊直，做灰饼。抹底层灰前必须先横线找平，立线吊直，弹出基准线和墙裙、踢脚板线。先用托线板检查墙面平整、垂直程度，并在控制阳角正的情况下大致确定抹灰厚度后(最薄处一般不小于7mm)，挂线做灰饼(灰饼厚度应不包括面层)。在地面上弹出十字线作为基准线，并结合墙面平整、垂直程度大致确定墙面抹灰厚度，并吊线“做灰饼”，“做灰饼”时应先在左右墙角上各做一个标准饼，然后用线锤吊垂直线做墙下角两个标准饼(高低位置一般在踢脚线上口)，再在墙角左右两个标准饼面之间通线，每隔1.2m~1.5m左右及在门窗口阳角等处上下各补做若干个灰饼。

　　2. Hang straight and make gray cakes. Before applying the bottom layer of plaster, it is necessary to level the horizontal line, hang the vertical line straight, and mark the reference line, wall skirt, and skirting board line. First, use a wire support board to check the flatness and verticality of the wall surface, and roughly determine the plastering thickness (generally not less than 7mm at the thinnest point) while controlling the positive angle. Then, hang a line to make a plaster cake (the plaster cake thickness should not include the surface layer). Pop a cross line on the ground as a reference line, and roughly determine the thickness of the wall plastering based on the flatness and verticality of the wall. Hang a line to make a "plaster cake". When making a plaster cake, first make a standard cake on each corner of the wall, and then use a plumb bob to hang a vertical line to make two standard cakes at the bottom corner of the wall (usually at the top of the skirting board). Then, make a line between the two standard cake surfaces on the left and right corners of the wall, and add several plaster cakes every 1.2m~1.5m and at the corners of doors and windows.

　　3.墙面冲筋：待灰饼结硬后，使用与抹灰层相同的砂浆，在上下灰饼之间做宽约30~50mm的灰浆带，并以上下灰饼为准用压尺推平。冲筋完成后应待其稍干后才能进行墙面底层抹灰作业。

　　3. Wall reinforcement: After the plaster cake has hardened, use the same mortar as the plastering layer to create a mortar strip with a width of about 30-50mm between the upper and lower plaster cakes, and use a pressure ruler to flatten the upper and lower plaster cakes. After the reinforcement is completed, it should be allowed to dry slightly before carrying out the plastering work on the bottom layer of the wall.

　　4.做护角：根据砂浆墩和门框边离墙面的空隙，用尺规后，分别在阳角两边吊直和固定好靠尺板，抹出水泥砂浆护角，并用阴角抹子推出小圆角，最后利用靠尺板，在阳角两边50mm以外位置，以40度斜角将多余砂浆切除、清净。

　　4. Make corner protectors: According to the gap between the mortar pier and the door frame edge and the wall surface, use a ruler to hang and fix the guiding board on both sides of the external corner, apply cement mortar corner protectors, and use a corner scraper to push out small corners. Finally, use the guiding board to cut off and clean the excess mortar at a 40 degree angle 50mm away from both sides of the external corner.

　　5.抹底层灰和中层灰：在墙体湿润的情况下抹底层灰，对混凝土墙体表面宜先刷水泥浆一遍，并在不同材质结合处挂钢丝网，与不同材质的接触面不低于30cm,随刷随抹底层灰。分层抹面，若抹灰层局部厚度超限(一般在20～35mm之间)，则应在抹灰层之间加设钢丝网片。 钢丝网固定式：采用2.5×28mm镀锌水泥钉固定， 钢丝网挂设在固定时钢丝网须摊平拉紧。固定钢丝网边缘时，水泥钉宜布置在离钢丝网边线2～3cm处，以便压紧钢丝网，不使其边缘翘曲。钢丝网片与抹灰基层搭接不小于100mm，钢丝网片之间搭接亦不小于100mm。水泥钉间距不大于300mm。

　　5. Apply bottom and middle layer plaster: Apply bottom layer plaster when the wall is wet. It is recommended to brush the surface of the concrete wall with cement slurry first, and hang steel wire mesh at the joint of different materials. The contact surface with different materials should not be less than 30cm, and apply bottom layer plaster as needed. Layered plastering, if the local thickness of the plastering layer exceeds the limit (generally between 20-35mm), steel wire mesh should be added between the plastering layers. Fixed steel wire mesh: fixed with 2.5 × 28mm galvanized cement nails. When the steel wire mesh is hung and fixed, it must be flattened and tightened. When fixing the edge of the steel wire mesh, cement nails should be placed 2-3cm away from the edge of the steel wire mesh to compress it and prevent the edge from warping. The overlap between the steel wire mesh and the plaster base shall not be less than 100mm, and the overlap between the steel wire mesh shall not be less than 100mm. The spacing between cement nails shall not exceed 300mm.
