Abstract

The invention provides a method for using wall paint to decorate the wall of a building. The wall of the building includes the inner wall and the outer wall of the building. The method comprises the following steps: step A, first use The cement mortar layer is smoothed; Step B is to wipe the waterproof and anti-cracking mortar layer; Step C is to apply wall paint; wherein the waterproof and anti-cracking mortar includes the following components: white cement, quartz sand or river sand with a particle size of 50-100 mesh, Calcium carbonate, redispersible latex powder, water retaining agent hydroxypropyl methylcellulose and water repellent silane. Applying the waterproof and anti-cracking mortar provided by the present invention and the corresponding construction method, after several years of testing, the application area has reached millions of square meters, and the obtained decorative wall surface has no quality problems such as cracking, falling off, water spots, and mildew.

Description

Technical field [0001] The invention relates to the field of architectural decoration, in particular to a method for using wall paint to decorate the wall of a building and a corresponding waterproof and crack-resistant mortar. Background technique [0002] In the past 30 years, with the vigorous development of my country's construction industry, various internal and external wall surface materials have emerged one after another, of which emulsion paint or mortar accounted for a certain proportion; however, the walls used in recent decades, especially the external walls, have many quality problems. , Cracking, shedding, water spots, and mildew can be seen everywhere, which brings an extremely indecent side to the beautiful city. [0003] With these problems in mind, the research and development team of the present invention has found the root of the problem through repeated research, which is mainly caused by the building filler (putty powder) used in the existing building emulsion ...
