7. In the painting of the color of the arch, the paint can be mixed with the paint in the paint that is sprayed again and again. It is also possible to build a fireproof paint to the design thickness and add a cover paint.
8、底层施工完成后,应及时根据设计腰线进行放线弹墨,对腰线以下及时压光。
8, after the completion of the underlying construction, the line should be designed according to the design waist line in a timely manner.
9、在大面积施工前,应先选取30米作试验段,取得成功经验后再推开实施。
9, before a large area of construction, 30 meters should be selected as the test section, and after successful experience, the implementation will be carried out.
10、底层防火涂料施工完成后,每道施工缝处及时切一条环向缝,切缝要整齐圆顺。
