Problems solved by technology

The high moisture content of the base layer will cause the bond between the putty layer and the base layer to be weak, which will directly affect the use effect of the exterior wall paint, and seriously cause the gradient and unevenness of the paint color

Embodiment Construction

[0007] The technical solution of the present invention will be described in detail below through a best embodiment, but the protection scope of the present invention is not limited to the embodiment.

[0008] A construction method for exterior wall paint finishing, which mainly includes: the first step is to treat the base layer, and apply an anti-alkali sealing primer to the target wall; the second step is to roughen the base layer of the target wall, using No. 1 sandpaper Grinding is performed so that large grains of sand holes are avoided. The third step is to use a high-power fan to dry the polished wall base, and the fourth step is to scrape the putty layer in two batches along the mutually perpendicular directions, that is, the first batch is scraped from top to bottom, and the second is scraped along the vertical direction. Scraping in the horizontal direction, the scraping in the horizontal direction should be from the far end of the body to the proximal end of the bod...

Abstract

The invention discloses a construction method of exterior wall coating decorative finish. The method mainly includes the following five steps of performing base layer processing; subjecting a target wall base layer to texturing processing; blow-drying a well polished wall basement by using a high-power fan; subjecting a putty layer to batch scraping for twice along a vertical direction; and painting coatings. By means of the construction method, the problem that exterior wall coatings are not even in colors due to the fact that the target wall base layer is overhigh in moisture content is solved, the problem that putty scraping is not even and incomplete during the process of twice batch scraping of the putty is avoided, and alkali-resistant closed base coatings are painted on the target wall so that alkalization and color crossing of the exterior wall coatings are effectively prevented.

Description

technical field [0001] The invention relates to an exterior wall construction method, in particular to a construction method for exterior wall putty scraping and paint finishing. Background technique [0002] At present, it is very common to use paint decoration on building exterior walls, and exterior wall paint has become an important sub-item of building decoration. In order to ensure the uniform color of the paint and the long-lasting service life, putty is generally first scraped on the wall where the paint is painted. However, in the traditional construction habits, we found that the effect of exterior wall coatings is often unsatisfactory, mainly reflected in the fact that the exterior walls of many buildings will suffer alkali and color bites in a short period of time after the coating dries. , and many times you will see obvious brush lines and trachoma, such construction effects will greatly reduce the appearance of the entire building exterior wall. After analyz...
