The specific process of wall decoration is accurat

  • Detail

Every day, everyone will see that if the wall is not well done, it will not only have an impact on the overall environment of the home, but also make the residents feel very bad. As the decoration cost of the wall is related to the size and materials, the decoration cost cannot be generalized. It is suggested that relatives can calculate according to the wall size of their own home. What are the wall decoration processes

1. Comprehensively check and distinguish the wall

identification method: wet the wall with water and scrape the wall with a shovel. There are two kinds of wall conditions:

(1) cement wall: it is difficult to shovel away. It is necessary to comprehensively check whether the cement wall in the blank room that needs to be painted is solid and flat. If the plastering layer of the wall is not strong enough or there are large hollows, cracks, holes and other engineering quality problems, it is recommended to complain to the developer or the property and ask it to redo. The province has to be saved

(2) putty wall: if it is white powder plus glue, the putty must be removed and the wall must be made again. This kind of putty is commercial in real estate, and most of it is not environmental friendly

2. Finished product protection

there will be dust during wall treatment, and it is inevitable that gypsum, mortar, water-resistant putty, paint and other decoration materials will fall during construction, so we must protect the finished decoration products in the room in advance

3. Sealing layer treatment (interface treatment agent and caulking gypsum putty are required)

(1) remove hollowing, wet the white powder layer of the wall with water, and shovel off the wall skin. Before the decoration officially starts, the hollowed wall needs to be cleaned. It is recommended to use a cutting machine to cut and remove the hollowed wall according to the size of the hollowed wall, so as to remove the hidden danger of cracks in the future.

If the wall surface of the house delivered by the developer is white putty instead of white cement leveling, it must be eradicated. The base course is not firm and easy to be powdered, so it is useless to make any good materials on it

(2) roll the interface agent on the wall to clean up the floating ash and improve the adhesion. Brush off the white powder and floating ash on the wall with coarse steel, roll the entire wall with interface agent once, or roughen the interface agent for sealing, so as to enhance the adhesion between the sealing layer and the leveling layer

(3) use leveling repair mortar to repair hollows, trunking, holes, and caulking gypsum for trench treatment. The repaired walls and walls with slight cracks need to be covered and pasted with anti crack bandages along the joints. It is strongly recommended to cover and paste the repaired walls with white cloth, and then use caulking gypsum to cover and smooth them. Joints and nail holes between gypsum products and gypsum boards must be filled with caulking gypsum and smoothed

4. Thick leveling layer treatment (professional leveling and repairing mortar is required)

rough walls with good flatness (the flatness of the blank room delivery specification is ± 3mm) do not need to use leveling and repairing mortar for thick leveling, but directly use water-resistant putty or functional ecological putty for fine leveling. If the wall surface is uneven or shoveled through the wall, it is recommended to use professional thick leveling materials to level and repair the wall surface with mortar, so as to fine level and scrape water-resistant putty. The effect is not only good, but also save putty

5. Fine leveling layer treatment (water-resistant putty and functional ecological putty need to be used in humid areas in the south of the Yangtze River)

after the thick leveling layer is treated, the water-resistant putty or other functional ecological putty can be scraped for fine leveling. The construction should be carried out according to the requirements of the putty construction instructions, especially pay attention to the precautions such as full and uniform mixing, scraping thickness and polishing, so as to avoid man-made problems caused by improper construction technology

6. Polishing putty

the water-resistant putty will become extremely solid after it is stabilized, hardened and dried (generally 5-7 days), and it will become extremely difficult to polish at this time. Therefore, it is recommended to polish the putty 1-2 days after the putty is applied. Polishing is optional. At night, use an electric bulb of more than 200 Watts close to the wall for lighting (it also needs to be leveled with a bulb during the day), and check the flatness while polishing
