Everyone and every day will see such things as "wall". If the wall is not well done, it will not only affect the overall environment of the home, but also make the residents feel very bad. From the perspective of environmental protection, the average wall surface will use 1-3 kilograms of various materials per square meter from rough to finished decoration. If these materials exceed the standard, the consequences will be unimaginable. Strictly speaking, the decoration of the wall during home decoration has included "decoration" and "decoration"

"wall" this kind of thing, everyone will see every day. 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. From the perspective of environmental protection, the average wall surface will use 1-3 kilograms of various materials per square meter from rough to finished decoration. If these materials exceed the standard, the consequences will be unimaginable

strictly speaking, the decoration of the wall during home decoration has included "decoration" and "decoration", in which the sealing, leveling and whitening of the bottom layer are the scope of "decoration" (strong foundation, long-term benefit from one-time construction), while painting, wallpaper, modeling wall, etc. can be regarded as "decoration" (strong decoration, which can be replaced regularly)

in order to facilitate your understanding, according to the general home decoration process, I divide the wall from blank to painting completion into eight steps for your reference:

the first step of wall decoration [inspection and treatment of wall status]

situation 1: cement wall. This is a common situation when a new house is handed over. Comprehensively check whether the cement wall to be painted is solid and flat. If the wall is not strong enough or there are large cracks and holes, it is recommended to complain to the developer or the property and ask them to redo or repair

case 2: white wall. Now many commercial houses are already white walls when they are handed over. They look clean, but in fact, they may have greater hidden dangers. First of all, we must check the firmness of the existing wall to see whether the existing white materials are water-resistant. If the water resistance is not good or the water resistance is ordinary, it should be removed and redone from the perspective of long-term use. As for short-term use, it can also be retained, but it is best to do one curing before other steps. At the same time, you should also check whether there is hollowing on the wall as a whole. If there is hollowing, you must shovel it off. Other inspection items are the same

case 3: the wall has been decorated. The wall surface has been decorated with wallpaper or latex paint, which is a common situation in second-hand houses. Generally speaking, the original surface decoration should be removed before such secondary decoration. If it's wallpaper, you should remove it first. If it's latex paint, you should polish it first. After the surface decoration is removed, you can refer to case 2 to decide whether to shovel the wall

★ special note:

no.1 checking whether the wall is solid and flat is a step of house inspection. See if the wall is solid. For the cement wall, you can do this: find a hard object (such as keys, screwdrivers, etc.), and draw a line on the wall to see if it will make a pit and fall seriously. There is no shortcut to find cracks and holes, only care and patience

no.2 there is more water in the kitchen and bathroom. It is recommended that the facade wall be tiled and the top wall be suspended. These two processing methods are not covered in this article, and will be discussed separately later if necessary

no.3 white wall. Check whether the material is water-resistant. You can operate as follows: find a wall, pour a little water, and rub it with your hand to see if it will become white paste. If you can poke through the white layer by hand, it is no water resistance. If you rub your hands with white, but you can't destroy this layer of white material, it means that the material has certain water resistance, so you can find a few more points to test. If the hands are almost white and not sticky when rubbed with hands, it indicates that the water resistance is very good

no.4 if the white wall has poor water resistance, but is unwilling to shovel the wall for some reason (such as short-term residence), the curing work should be done carefully. See Step 3 for details

no.5 in addition to water resistance, hollowing is also a big problem that must be taken seriously. Now, although some developers use water-resistant materials (such as water-resistant putty) on the surface, they use inferior gypsum powder to make thick leveling. It will not take long for the house to be delivered to show hollowing and cracking, and even a whole piece of cracking will occur after a longer time. In case of such empty drum, you'd better shovel it off and redo it! No.6 check whether the old wall is solid: 1 visually check whether there is peeling, cracking and bulging, and if there is, it is not solid; 2 find a blunt object (such as a small hammer) and knock on the wall to check whether there is an empty drum. If there is, it is not solid; 3 after polishing the emulsion paint, pour some water and shovel it with a shovel to see whether it is easy to shovel it off. If it can be easily shoveled off, it is not strong

the second step of wall decoration [finished product protection]

generally, the carpentry furniture and ceramic tile paving should have been completed before the wall treatment. If it is the renovation of second-hand houses, there may be more finished products. In order to prevent the finished products from being polluted by the wall covering, dust and paint in the process of wall treatment, the existing finished products in the room should be carefully protected. Otherwise, once the loss is caused, it is too late to repent

★ special note:

the protection work is listed as a separate step in order to increase everyone's attention to it. Don't leave any regrets because of carelessness, especially when there are some dirty finished products at home, we have met too many friends who ask about cleaning methods

the third step of wall decoration [sealing layer treatment]

after the first two steps, we have made enough preparations (if we need to shovel the wall, it should be finished by this time). Now we can start to seal the wall. Sealing includes two aspects: one is the filling of cracks, slots and holes, which can be done with repair gypsum products; Another is the curing of the wall base, which is usually done with curing agent. There are also some cases that need to be solved with stickers (kraft paper) with stronger curing ability
