Plastering on the wall refers to the application of cement mortar, mixed mortar, and white-gray mortar on the wall surface. The scientific wall plastering work can function as moisture-proof, weather-proof, heat-insulating, etc., to avoid the erosion of wind, rain, snow, etc. on the walls of buildings. Wall plastering is divided into general plastering and decorative plastering; general plastering is followed by brushing latex paint, imitation porcelain, etc., and decorative plastering can be used directly as the most surface decoration of buildings, such as shamrock, terrazzo surface, Water brush stone. Plastering of the wall is an important part of the decoration. It can be said that the basis of the wall decoration is the plastering of the wall. If the operation is not good enough, it will easily lead to cracks on the wall, etc. What is the step of plastering the wall? Need to pay attention? Here's a look at the correct way to plaster the wall. 
The correct way to plaster the wall
1. Grassroots cleanup
Before the plastering of the wall, it is necessary to do a thorough cleaning of the wall, so that the wall surface is free of dust and particulate contaminants, oil stains, residual mortar and other contaminants. If the wall is not full, you need to repair the defective area.
2. Wet wall
After the wall is cleaned, in order to ensure the wettability of the wall, it is possible to water the water several times to make the wall wet. It is usually carried out on the day before the plastering of the wall. This step can be said to be a step that must be performed. This can prevent the wall base from excessively absorbing the moisture of the cement mortar, resulting in shrinkage and emptying; this amount of water needs to infiltrate the human body. The block depth is preferably 5 to 10 mm. When the wall is plastered, the wall is still dry and wet, and the water should be sprayed again to make the wall wet to prevent the basement layer from absorbing moisture.
3. Hanging net hair
At the intersection of cement and concrete and aerated blocks of this type of wall material, full wire mesh treatment should be carried out to prevent wall cracking. The proposed grid is a wire mesh with a grid spacing of 10 to 20 mm and a diameter of 1.5 mm. The overlapping position of the mesh and the base layer of each material should not be less than 100mm.
4. Find the rules, apply ash cake
According to the flatness and vertical condition of the wall surface, and the thickness to be completed, the thickness of the plastering on the wall must be determined after on-site measurement, but the thickness of the plastering layer must not be less than 7 mm. After the thickness is determined, ash cakes shall be applied by means of wire fall, square rule, and pull-through wire; ash cakes shall be made of 1:3 cement mortar in a shape of 30 to 50 mm square with a horizontal distance of approximately 1.5 to 2 m.
5. To protect the corner, punch
Before the plastering of large areas of the wall, in order to ensure the uprightness and squareness of the outer corners of the wall, the corners of the doors, windows, cylinders, and other corners of the yin and yang must be treated before the plastering. The operation method is shown in the figure; the corner line also plays the role of punching, so the mortar used is the same as the ramming mortar, and the height should not be more than 2 meters, and the width on both sides should not be less than 50mm.
Plastering construction considerations
1, first wipe a thin layer of gray (adhesion layer, 2 ~ 5mm is appropriate), thin gray layer requires mortar compaction, fully squeezed into a small gap;
2, layered scraping, each time the plaster thickness of the wall should be suitable for 7mm ~ 9mm, leveling, flush at the height of the crush;
3. Fully inspect whether the bottom ash is smooth, ensure that the yin and yang corners are square, the ash in the pipeline is flush, the junction between the wall and the roof is smooth, and the vertical and level of the wall surface are checked with the supporting line. The wall plastering should be promptly cleaned and scattered. The mortar on the ground.
The above is the correct way to bring the wall plastering and what are the precautions, wall plaster this step is very important, so we can learn about this knowledge before the renovation, so that after the renovation can be With help, I hope that the above introduction can help a friend in need!
