Putting putty in the decoration of the house is a must-have part, but some people don't know much about the putty. In fact, the putty is when the original wall or the ground is more tight and firm, and the plane is smoother after the putty is finished. floor construction technology putty what? Notes putty scraping the floor of what? then you follow renovated home network Xiaobian a look at the content of it! First, the construction process of floor putty 1. Base treatment: cast-in-place concrete wall surface, due to various reasons such as floor slab, material, and release agent, the wall surface is poorly flat, and there are often pores, honeycombs, pockmarks, yin and yang angles, and bulging. The convex part is flat and the concave part is filled and filled. For prefabricated concrete floor slabs and slab bases, it must be brushed by a special person to remove the surface floating sand, sputum, dust and other debris. For the cement mortar paper ash surface layer, the surface base layer is required to be dry and solid (no floating oil). 2, the base layer repair: after the concrete roof and the seam are cleaned, the gypsum putty is scraped with a steel scraper on the larger defect parts such as the honeycomb, and the horizontal surface is smoothed. scratch). Gypsum putty mix ratio (weight ratio) is gypsum emulsion: cellulose aqueous solution (concentration 5=100:5~6:60. Brushing alkali aqueous solution: brushing with 5μ degrees of caustic soda solution twice, if coated with 10μ degree Brush it once. You should rinse it with water and then dry it with the brush before proceeding to the next step. 3, the application of adhesive (milk paste): spray the glue before spraying the putty together must be uniform spray must not have leakage spray glue ratio (weight ratio) for water: emulsion = 100: 15 ~ 20. Scrape large white putty: Scrape putty should be scraped with steel scraper. Pay attention to the upper and lower sides. The two scrapers should be clean. It is not allowed to leave floating putty. When scraping putty, it should be prevented from being stained or mixed with sand and other debris. Large white putty ratio (weight ratio) is white powder: talcum powder: cellulose solution. Second, the construction precautions of the floor putty 1. When the base layer is strong, it should be sealed with a primer before scraping the putty, so as to prevent the glue in the putty from being absorbed by the base layer to affect the adhesion of the putty. 2, master the inclination of the tool when scraping, apply uniform force to ensure that the putty is full. 3, in order to avoid excessive shrinkage of the putty, cracking and shedding, do not over-thickness at one time. According to the characteristics of different putties, the thickness is 0.5~1mm. 4, do not apply too much round-trip, in order to avoid the appearance of peeling, shedding or extrusion of the rubber in the putty, sealing the surface is not easy to dry. 5. According to the performance of the coating and the condition of the base layer, select the appropriate putty and scraping tool. When filling the hole and crack in the base layer with the putty knife, the index finger presses the blade, and the putty is pressed into the defect with the rib, and the filling is completed and filled. The putty is scraped clean and the putty marks are minimized. The above is a detailed answer to the Xiaobian, I don't know if you are satisfied with the introduction of the decoration home network Xiaobian~ If you want to know more about the exciting content, please continue to pay attention to our decoration encyclopedia!
