Want to know what is putty, we must first understand what putty is, and the role of putty is that. Putty is a kind of decorative material on the surface of a smooth wall. It is a thick paste-like paint, and it is an indispensable step before painting paint. The role of putty is to eliminate the surface defects of the base layer and improve the flatness of the base layer. The construction of putty is good or bad, affecting the quality of future decoration, and some of them are not suitable when putty is applied, so it is easy to cause blistering, peeling, and coating shedding. The following Xiao Bian will introduce the approval of putty steps for everyone. A detailed description of the putty step 1. Primary treatment : Due to various reasons such as concrete wall slabs, materials, and partitioning agents, the flatness of the wall surface is relatively poor, and pores, honeycombs, and angles between the yin and yang angles and bulging are often encountered. Therefore, the convexity is required. Smooth and smooth, concave to fill up. For prefabricated concrete floor slabs and slab joint bases, it must be brushed again by a special person with a wire to remove dust, sand, dust, and dirt from the surface. For the cement mortar paper ash surface layer, it is required to dry and dry the surface base layer, and it is solid and clean (no floating soil oil). 2. Grass-roots repair : After the concrete roof and board seams are cleaned, the gypsum putty is filled with flat steel scraper and flattened on the relatively large defects such as honeycomb, and the horizontal surface is scraped and scraped again. scratch). The ratio of gypsum putty (weight ratio) was gypsum:emulsion: cellulose aqueous solution (concentration 5%)=100:5 to 6:60. Brush fire alkali aqueous solution: brush with 5% concentration of alkali solution for two times, if you use a 10% concentration brush again. Rinse with brush immediately with water and allow to dry before proceeding to the next procedure. 3. Coat the adhesive : We will spray the glue once before the putty. When spraying, we must spray the glue once. When spraying, it must be even and consistent. There can not be a floor spray. The glue ratio is: fresh water: emulsion = 100:15~20. The putty shall be scraped back and forth with a steel scraper. Pay attention to the up and down and left and right joints. Clean between the two scrapers. Do not allow fins to be putty. Prevent dusting or mixing with sand or other debris when applying putty. The ratio of white to putty (weight ratio) was large white powder: Talc powder: Cellulose solution (concentration 5%): Emulsion=60:4o:75:2~4. 4. Repair grinding and putty survival : After the first putty scraping, the site after the first repair should be reviewed. If there is any problem, use putty to make up the leveling at the collapsed part. After the putty is dry, polish it with sandpaper. Ping, sweep the net; approved putty must be carried out twice, until the first putty dry after the second batch, generally requires at least two times to survive. After the putty is approved, the surface is required to be flat and the texture texture is uniform, otherwise, the inconsistency of the color depth is likely to occur, and the decoration effect is affected. Second, the issue of putty 1. Ingredients should be added to the water powder, water should not be added to the powder. 2. The prepared slurry should be used within 3 hours. 3. The second time putty scraping thickness in principle should not exceed 3mm. If the defects on the work surface require a large thickness, multiple scraping methods may be used, or fine sand may be added at a dry powder:sand=1:1 weight ratio. 4. The construction site temperature should be above 5 °C. 5. Avoid construction with oily polyester, polyurethane paint at the same time. Lots of Putty Steps 6. Walls with serious alkali or clear water cannot be directly applied. They should be qualified after special treatment. 7. When the climate is too dry or windy, there should be protective measures (such as the prohibition of ventilation and regular watering of the ground). Strengthening the putty is an important part of the renovation, which gives our building a beautiful scene. What is a putty? How much do you know about putty? What about the putty step? 8. Putty maintenance, to avoid excessive evaporation of water caused by dry cracking, off powder, and should be on the water after 24 hours. 9. After the construction is completed, clean the buckets and tools in time to avoid the residue slurry from being hard to clean after curing.
