The treatment of blank wall is an important link in house decoration. Proper treatment can lay a good foundation for the subsequent decoration work, and also enable the wall to achieve the ideal decorative effect. The following is a detailed introduction to the treatment methods and related matters needing attention of the blank wall for you.

The first is grass-roots treatment. There are usually impurities such as dust, oil pollution and loose objects on the surface of the blank wall, which need to be cleaned comprehensively first. You can use brooms, vacuum cleaners and other tools to remove dust. For the parts with serious oil pollution, you can use cleaning agents to wipe them. If there are cracks, holes and other defects in the wall surface, it needs to be filled with gypsum or special repair materials. Small cracks can be directly repaired with putty, and larger cracks need to be embedded with bandages or mesh cloth before filling them to prevent cracks from cracking again.

The next step is wall leveling. Uneven wall will affect the subsequent decoration effect, so leveling is needed. Commonly used leveling materials are cement mortar and putty powder. If the deviation of wall flatness is large, coarse leveling can be carried out with cement mortar first, and fine leveling can be carried out with putty powder after drying. When daubing putty, it is generally necessary to daub it for 2-3 times, and the interval between each time should be determined according to the weather and material description, usually 1-2 days. The thickness of each application should not be too thick to avoid cracking.

Then it is sanded. After the putty is dried, it is necessary to polish the wall surface with sandpaper to make the wall surface smoother and flatter. The mesh number of sandpaper should be selected according to the flatness and grinding stage of the wall. Generally, rough sandpaper is used for preliminary grinding first, and then fine sandpaper is used for fine grinding. Pay even attention when polishing to avoid polishing marks.

Finally, the wall decoration. After the previous treatment, the wall can be decorated, such as painting latex paint and pasting wallpaper. When painting latex paint, we should pay attention to selecting products with good quality and high environmental protection performance, and make deployment and construction according to the requirements of the manual. When pasting wallpaper, pay attention to the splicing and alignment of wallpaper to avoid problems such as empty drum and edge warping.

In the process of dealing with the blank wall, there are also some matters needing attention. When treating at the grass-roots level, it is necessary to ensure that the wall is completely dry before the next step of construction, otherwise it will affect the adhesion and drying speed of subsequent materials, and even lead to problems such as moldy and falling off the wall. In the process of wall leveling, it is necessary to control the proportion and coating thickness of cement mortar and putty powder to avoid cracking and hollowing. When sanding, you should pay attention to protective measures, such as wearing masks and gloves, so as to avoid inhaling dust and causing harm to your body. In the stage of wall decoration, we should pay attention to the temperature and humidity of the construction environment, and avoid the construction in the environment of high temperature, high humidity or low temperature, so as not to affect the decoration effect.
