Anti-cracking putty for building and construction method thereof

Abstract

The invention discloses anti-cracking putty for a building and a construction method thereof. The anti-cracking putty consists of the following components in percentage by weight: 60 to 65 percent of filling material, 28 to 32 percent of building glue, and 4 to 8 percent of saw dust; and the components are mixed and stirred into even paste and used on a construction site. The construction method comprises the following steps: using a scraper to fully scrape a wall surface which is coated with an interface agent to flatten large area of the wall surface; at the same time of primarily scraping the putty, bonding a wide alkali-resistant glass fiber net at the connection part of a building block wall, a concrete beam and a concrete column, re-scraping the glass fiber net after the bonding by using the scraper, and pressing the glass fiber net in the putty; after the primary putty is dried, scraping the secondary putty; and next, smearing the smooth putty and paint. The anti-cracking putty and the construction method have the characteristics of simple and convenient construction, easy operation, good ductility, thinner thickness than common plastered ash, little material loss, low cost, economical expense and the like, and can accelerate the project progress, shorten the project construction period and effectively reduce cracks on the wall surface.

Description

technical field [0001] The invention relates to a leveling putty for construction, in particular to an anti-crack putty. Background technique [0002] With the rapid development of my country's construction industry, putty has become one of the main decorative materials in interior and exterior wall decoration. It is more and more popular in the market for its good decoration, durability, ease of construction and good performance-price ratio. welcome. However, with the increase of the amount of work, there have been some common engineering quality problems, the most serious of which is that after a period of time, such as one year after the completion of the painting, the wall will appear cracks and other phenomena, which will not only bring damage to the building. In addition, the coating loses its decorative properties, which seriously affects the function and appearance of the building. Contents of the invention [0003] The object of the present invention is to overco...
