Construction method for shell powder wall coating layer

Abstract

The invention discloses a construction method for a shell powder wall coating layer. The method comprises the following steps: step one, checking flatness of a wall surface, filling-in a cavity or a seam by using putty powder or shell powder paint; adding shell powder and plain boiled water to a container for loading, wherein a proportion is 1:1.5-1:1.9, and stirring by using a stirrer; stirring amaterial and stewing for half an hour to one hour, and stirring again for 1-2 minutes while scraping on a wall; step two, scraping for the first time by using a spatula, wherein a scraping thicknessis about 0.5 mm, and performing the second time of spraying while the wall surface is dried fifty percent, wherein a thickness of the second time of spraying is should be 0.8 mm, and compacting and levelling by using the spatula while the wall surface is dried eighty percent; and step three, shell powder printing: according to a size of the wall surface, planning a position of a pattern, adding shell powder with a specific color to 90% of clear water by construction water quantity, adequately and uniformly stirring, enabling a pre-engraved pattern template to be pasted on the wall, smearing for two times, levelling, and uncovering the template while dried seventy percent. The wall surface prepared by the method is environment-friendly and non-toxic, damp-proof and humidified, and capable of purifying air, and achieving the decorative effect the same as wallpaper.

Description

technical field [0001] The invention relates to a construction method of shell powder wall coating. Background technique [0002] To decorate and treat the interior walls of buildings, the following methods are generally used: seam treatment such as gypsum and plywood - scraping putty for leveling - painting latex paint or pasting wallpaper. The mainstream method, but there are still some problems, mainly in: Due to the limitation of the current production technology level, volatile organic compounds are common in liquid wall treatment agents, putty, wallpaper glue, latex paint, wallpaper and other materials VOC and free formaldehyde, these substances pollute the indoor environment and cause harm to people's health; the service life of this type of construction method is 5-10 years, and the phenomenon of drumming and shedding is obvious beyond the time limit; the surface of latex paint or wallpaper is a layer The dense paint film cannot absorb indoor harmful gases, adjust h...
