为了保证抹灰表面平整。光滑洁净、不空鼓,不开裂,要求分层抹压。一般分为底层、中层和面层,高级抹灰还要求有几遍中层。多层抹灰层的材料一般都不相同,要把价格低廉的放在底层和中层,把价格高的材料放在面层,这样就带来由于材料性质的不同是否会引起各层之间粘结不牢而空鼓或脱落的问题,其中也包括底层和基层的粘结牢固的问题。砖墙抹灰一般为白灰砂浆打底,白灰罩面,因为砖墙和白灰砂浆之间以及白灰砂浆与罩面麻刀白灰之间粘结力很强,所以麻刀白灰罩面的墙面不易空鼓和脱落,而水泥砂浆的门窗套和水泥砂浆护
In order to ensure that the plaster surface is flat. Smooth and clean, not empty, no cracking, requiring layered pressure. Generally divided into the bottom, middle and surface, senior plaster also requires several times in the middle. The material of the multilayer plastering layer is generally not the same. The low cost should be placed on the bottom layer and the middle layer, and the high-priced material should be placed on the surface layer. This will bring about the difference in material properties that will cause the layers to stick together. The problem of loose or loose or falling off, which also includes the problem of firm bonding between the bottom layer and the base layer. Brick wall plastering is generally made of white-gray mortar and white-gray finish. Because the adhesion between the brick wall and the white-gray mortar and between the white-gray mortar and the white ash of the overlaid machete is strong, the wall surface of the white-gray masonry is not easy. Hollowing and shedding, while the cement mortar door and window cover and cement mortar protection
