Abstract
The invention belongs to the technical field of the inner wall painting, and particularly relates to a construction method for an inner wall without painting. The construction method comprises the following steps that (1) repairing processing preparatory work of a base layer of concrete and the lightweight wall is completed; (2) construction operation technology is carried out, specifically firstpass thick type cement polymer putty is scraped completely, after natural drying, grinding flat is carried out, the second pass thin type cement polymer putty is scraped completely, after natural drying, the grinding flat is carried out, the third pass thin type cement polymer putty is scraped completely, the thickness is about 1-2mm, after natural drying, the grinding flat is carried out, prime paint is painted, the putty is painted again, the grinding flat is carried out, the prime paint is painted partially, first pass primary layer painting is rolled and painted, and the first pass primarylayer painting is sprayed. The construction method for the inner wall without painting conforms to the related requirement of the state of energy-saving projects and pay attention to the research, development and utilization of green main materials, meanwhile, the management of the construction site is strengthened, the environmental awareness of on-site operating personnel is reinforced, the whole process of environmental protection monitoring and non-pollution treatment are realized, compared with the traditional painting techniques at the grass-roots level, energy is saved and materials are saved, and water and land are saved, and environmental protection benefit is improved.
Description
technical field
[0001] The invention belongs to the technical field of interior wall painting, and in particular relates to a painting-free construction method for interior walls. Background technique
[0002] With the acceleration of the urbanization process, the urban population base is increasing. In order to improve land use efficiency, the residential buildings in the first and second tier cities in China are basically high-rise residential buildings, and the structures are mostly in the form of frames or shear walls. Lightweight wall materials such as powder-steamed aerated concrete blocks, ordinary concrete hollow blocks, and light aggregate concrete small blocks are mostly used for interior partition walls. Traditional 20-thick mortar painting generally needs to be constructed in 2-3 layers. The construction period is long. Hollowing, cracking and even falling off are common quality problems, which often cause rework. Even if the hollowing part is cut off and re-cons...
