1, grassroots processing. Remove dust and dirt at the grass-roots level, fill holes, cut hair to a certain roughness, and sprinkle water for wetting. At the junction of different structures at the grass-roots level, a layer of metal mesh should be laid to avoid cracks, and the lap width of metal steel mesh and each matrix should not be less than l00mm. For the brick base, it should be fully compacted before plastering.

Indoor plastering shall be carried out after the installation of water, electricity and gas pipelines. Before plastering, the hole in the wall and floor through which the pipeline passes must be filled and embedded. The external corners of indoor walls, cylinders and doorways shall be protected by 1: 2 cement mortar, the height of which shall not be less than 2m, and the height of each side shall not be less than 50mm. Before the external wall plastering project construction, steel wooden door window frames, balcony railings and embedded iron pieces should be installed, and the construction holes on the wall should be blocked tightly.

2, the underlying plaster. The bottom plastering thickness is 5-9mm, which is used to make the plastering layer firmly combined with the base and layer.

3. the middle layer. After the bottom layer is dry, the middle layer is plastered, which is mainly used for leveling. The thickness is 5- 12 mm, and standard steel bars should be made. Before the middle plastering condenses, oblique marks should be drawn to combine it with the surface layer.

4. Surface courses. The surface layer thickness should be 2-5 mrn, which is mainly used for decoration, and the surface should be flat, smooth and crack-free. The total thickness of plastering is generally not more than 35mm, and measures should be strengthened when it exceeds 35mm.
