Paint brushing construction method

Abstract

The invention relates to a paint brushing construction method, which sequentially comprises the following steps of brick wall base surface cleaning, base layer brushing, putty priming and surface layer rolling coating. According to a method adopted in the base layer brushing step, firstly, a brick wall base surface is moistened through water spreading, a layer of cement paste is brushed, then, cement mortar is used for brushing, the first layer brushing thickness is 0.08 to 0.1cm, the second layer brushing thickness is 0.05 to 0.08cm, then, the scraping leveling is carried out through a darby, and finally, the floating leveling is carried out through a wood float. According to a method adopted in the putty priming step, the priming is carried out in two layers, the first layer putty priming thickness is 0.3 to 0.5cm, the second layer putty priming is carried out after 22 to 26 hours, the priming thickness is 0.2 to 0.3cm, and two work procedures of grinding leveling machine and sand paper are adopted for grinding leveling after the natural maintenance. According to a method in the surface layer rolling coating step, firstly, a layer of paint is brushed on the putty surfaces primed in the former step, the paint rolling coating is carried out once again after 3 to 5 hours, and then, the maintenance is carried out. The surface layer brushed according to the construction method is smooth, flat and uniform without cracks, in addition, convex-concave corners of wall posts are made into micro arc shapes, the appearance is attractive, simple and compact, and the dust accumulation cannot easily occur.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a method for painting interior walls and exterior walls of buildings. Background technique [0002] The painting process of the interior and exterior walls of the building determines whether the wall is smooth and beautiful. Unreasonable construction methods will lead to many quality problems, such as cracks after the putty dries, resulting in cracks in the latex paint. The reason is that the putty is too thick or scraped once. Unevenness, unclean treatment of the base layer, dust and sundries in the pits have not been cleaned up, putty cannot take root, etc.; and the surface layer is hollow and cracked. According to the regulations, layered priming and grid construction, due to the fact that the large area of ​​cement mortar is not divided into grids and layers, and the drying shrinkage varies, hollow cracks will be formed; in addition, when making the surface laye...

[0002] The painting process of the interior and exterior walls of the building determines whether the wall is smooth and beautiful. Unreasonable construction methods will lead to many quality problems, such as cracks after the putty dries, resulting in cracks in the latex paint. The reason is that the putty is too thick or scraped once. Unevenness, unclean treatment of the base layer, dust and sundries in the pits have not been cleaned up, putty cannot take root, etc.; and the surface layer is hollow and cracked. According to the regulations, layered priming and grid construction, due to the fact that the large area of ​​cement mortar is not divided into grids and layers, and the drying shrinkage varies, hollow cracks will be formed; in addition, when making the surface layer, because the base layer is not clean, The base layer is relatively dry, and it will also crack the surface layer
