In the process of house decoration, the treatment of blank wall is a key link, which directly affects the quality and effect of subsequent decoration. The following will introduce in detail the proper treatment method of blank wall and the aspects that need to be paid attention to in the treatment process.

First of all, a comprehensive inspection of the blank wall is the first step. It is necessary to carefully check whether there are cracks, hollowing and other problems on the wall. You can tap the wall with a small hammer and judge whether there is empty drum by sound. If cracks are found, small cracks can be treated with special crack repairing agent; For larger cracks, it is necessary to cut the cracks first and then fill them with cement mortar. If there is an empty drum, the empty drum part should be eradicated and repaired with cement mortar again.

Followed by the treatment of the wall base. This includes cleaning the dust, oil and other impurities on the wall. You can use brooms, vacuum cleaners and other tools to clean up and ensure that the walls are clean and tidy. After that, choose the appropriate treatment method according to the flatness of the wall. If the flatness of the wall is poor and the error exceeds 5mm, it is recommended to use gypsum to level the wall first. Gypsum has the advantages of fast solidification and strong adhesion, which can effectively improve the flatness of the wall. If the wall flatness is good and the error is within 5mm, you can directly blow putty.

Scraping putty is an important step in the treatment of blank wall. Generally, it is necessary to scrape the putty for 2-3 times, and the interval between each time is 1-2 days, so that the putty can be fully dried. Pay attention to the technique when scraping putty, try to keep it even and flat, and avoid sagging and bumps. After scraping the putty for the last time, use sandpaper to polish the wall to make it smoother and more delicate. Pay even attention when polishing to avoid polishing marks.

After completing the above steps, you can decorate the wall. Common wall decoration materials include latex paint and wallpaper. If you choose latex paint, you should first paint the wall with primer before painting. The primer can enhance the adhesion between the wall and the top coat, and at the same time, it can also play a role in moisture prevention and mildew prevention. Topcoat generally needs to be painted for 2-3 times, and a certain time should be separated between each time. If you choose wallpaper, you should first paint a layer of basement membrane on the wall to prevent the wallpaper from being damp and moldy.

In the process of dealing with the blank wall, we also need to pay attention to the following aspects. The temperature and humidity of the construction environment have great influence on the wall treatment effect. Generally speaking, the construction temperature should be between 5℃ and 35℃, and the relative humidity should be below 85%. If the ambient temperature is too low or the humidity is too high, it will affect the drying speed of putty and latex paint, leading to problems such as cracking and peeling on the wall. In addition, pay attention to safety during construction and wear protective equipment, such as masks and gloves. When using electric tools, we should operate in strict accordance with the operating rules to avoid safety accidents.
