The basic treatment of the wall to do a good job without overhauling the decoration

In the home improvement process, wall decoration is the key project of home improvement, and the treatment of the wall base that has a direct impact on the overall decoration effect of the wall is the most important task. Before the paving of the tiles or the scraping of the putty, the wall base is required. Check and repair to ensure the normal construction of the construction. Therefore, as the owner, it is necessary to master certain knowledge about the processing of the grass-roots grass-roots level. It is very possible to avoid the rework of the wall in the future. Here, follow the small series together to understand the precautions for handling the wall.

First, the role of the wall building structure needs to distinguish

The first thing to distinguish is which light walls, which are load-bearing walls, and which are internal heat-insulating walls. There is a simple way to distinguish between the light wall and the load-bearing wall: use a fist to pry on the wall. If you hear an empty sound, it is usually a light wall. If there is almost no sound, it is usually a bearing wall. If you can't make accurate judgments with a fist, then ask the property to ask. Lightweight walls are generally free to demolition and renovation in the decoration, and bearing walls are not allowed to demolition.

Second, the wall surface inspection

General focus on inspection of hollowing, cracking, flatness, verticality, and yin and yang angles.

1, check empty drum

Generally, a metal hammer is used to tap the wall. If you hear the empty voice, you must pay attention to it. There may be empty drums inside the wall, that is, the wall is not true. It is better to check the reason so as not to crack the wall in the future. , shedding phenomenon. Hollow drums will also affect future home use. For example, if you want to hang a picture on the wall, you may have a nail nailed in or the nails are loose, you can't paint, or the entire wall cracks or falls.

2, whether there is cracking

Cracking can usually be found by looking at the eye, looking for cracks, or looking for traces of cracks that have been repaired. At this time, it is necessary to determine what kind of crack is the crack, between the light wall and the load-bearing wall, or the construction hole (a construction hole for a transportation material opened between the walls inside the building during the construction of the building, after the building is built They will make up, but due to the differences in the time and the time of setting up the walls, the materials will sometimes be different, and there will be cracks around the original wall.

3, the level of inspection

Generally use a two-meter-long ruler (known in the industry as "two meters on the ruler") to check in multiple directions, and the verticality can be checked by a line hammer without professional tools. As long as the maximum gap between the ruler or the line hammer and the wall is not more than 8mm, we can use the decoration to level off. Because the flatness and verticality error within 5-8 mm of the wall leveling is generally not a separate fee (individuals who love the money to calculate another), but the basic treatment of more than 5-8 mm of the wall need to be extra It's costly, so you'd better find a developer or property and let them help you level it up to the margin of error.

4, Yin Yang angle check

The invagination is called the inside corner and the outside is called the outside corner. The yin and yang angles are checked with a special corner ruler. If there is no special corner ruler at home, check with tiles. Tiles are generally parallel squares. Inspection principle and flatness, the same degree of verticality requirements, 90-degree error in the wall within 5-8 mm is eligible, can be found through renovation, over the scope of the property to find.

Third, the wall leveling

Plastering plaster, as the name suggests, the main ingredient is plaster and other additives (usually sand). Suitable for concrete, aerated concrete, brick-mixed mortar wall base plaster thickness leveling. High-strength gypsum is similar to caulking gypsum. It is also a wall material mainly composed of high-strength and fine gypsum powder, supplemented by a variety of high-grade additives. It can be used for gypsum products, gypsum board joints, nails and other parts of the caulking , Bu Ping processing, but also applies to the repair of interior wall face holes, gaps, trunking and local flatness is poor local repair leveling, belonging to the sealing layer material.

Wall leveling more than 5-8 mm is to be charged separately, especially for old houses. Sometimes you really want to look flat horizontally and vertically. It may be difficult or even impossible (because some houses are slanted). A lot of money does not say that it still occupies indoor space. Therefore, it is recommended to find a vertical level. It is sufficient to level it from top to bottom, and it is not necessary to emphasize horizontal leveling.

Fourth, scratch (batch) water putty

The putty we talked about was referring to the "interior wall putty". I believe many people have no concept of putty before the renovation. In general, the main purpose of putty is only one: leveling is to find a very flat kind. However, with the progress of the times, the breakdown of putty is also very complicated, such as: water putty, elastic putty, anion putty and so on.

For the other functions of putty we can temporarily ignore, because there are ways to make up for the problem even if there is a problem in the later period, and we must pay great attention to water resistance. Once the putty is not water resistant, it is easy to appear unsturdy, easy to peel, easy to crack and so on. And in the second decoration is also very troublesome, to re-scavenge the original non-water-resistant putty after heavy wall treatment, and water-resistant putty is just a simple brush over the paint on it.
