怎样保证装饰工程质量怎样提高单位工程质量等级 9.基层为加气混凝土或炉渣空心砖墙面的抹灰这类轻质墙体材料墙面抹灰时极易产生空鼓、开裂等现象,造成这种情况多因底子灰配合比不合适,标号太高所致。在抹底子灰之前,先清理基层、清扫墙面,并喷(刷)一道界面处理剂,这样可增加底层砂浆与基层的粘结力。施工时,一边刷界面处理剂一边抹2:1:8水泥混合砂浆打底(厚3～5毫米),中层砂浆用1:1:6水泥混合砂浆(厚5～7毫米),第二天用1:2.5水泥砂浆抹面(厚3～5毫米),完成后次日洒水养护3～5天。
How to ensure the quality of the decoration project How to improve the quality of the unit project 9. The base layer is a kind of plastering of aerated concrete or slag hollow brick wall. This type of lightweight wall material is easy to produce empty drums, cracks, etc. This is due to the fact that the mix ratio of base ash is not suitable and the label is too high. Before wiping the base ash, first clean the base layer, clean the wall, and spray (brush) an interfacial treatment agent. This will increase the adhesion of the base mortar to the base layer. During construction, brush the surface treatment agent while wiping the 2:1:8 cement mortar (bottom 3 to 5 mm), and the middle mortar with 1:1:6 cement mortar (5 to 7 mm thick). Use 1:2.5 cement mortar to wipe the surface (thickness 3 ~ 5 mm), after the completion of the next day sprinkler curing 3 ~ 5 days.
