In the home decoration, the wall surface is the largest area project. Regardless of how the wall is decorated and decorated, the base layer treatment of the wall is very important. The wall occupies an important position in the decoration and has high quality requirements. If it is not handled properly, problems such as cracking and falling off may occur in the future, causing trouble to life. Next, follow the decoration home network Xiaobian to learn about the construction cost of the wall base treatment , the relevant content of the wall surface treatment construction steps !

Wall base treatment construction steps

First, check the wall

1. Cement wall

Inspection method: Use a hard and sharp object (such as a key, a screwdriver, etc.) to draw a stroke on the wall.

Discrimination criteria: If there are obvious scratches or slag on the wall, the quality is poor and more repairs are needed.

2, white wall

Inspection method: Splash water on the wall and rub the wall with your hand.

Discrimination criteria: If the white layer is completely punctuated by hand, it is not water resistant. If it is white when it is rubbed by hand, but it cannot destroy this layer of white material, it means that the material has some water resistance.

You can find a few more points to test. If the hand is rubbed, the hand is almost white and not sticky, which means that the water resistance is very good.

3, the old wall

Inspection method: visually check whether there is peeling, cracking, and drumming; find a blunt device (such as a small hammer) to knock on the wall surface, check if there is an empty drum; polish the latex paint and pour some water, and shovel it with a spatula.

Discrimination criteria: If there is peeling, cracking, drumming, hitting a hollow drum with a hammer, and easily hanging with a blade is a less solid wall.

Second, the sealing of the wall base layer

If the shovel wall has been shoveled to the red brick layer, it is recommended to do the cement plaster first, and the cement ash should be cured and dried before the wall sealing process.

Hydropower transformation needs to be grooved on the wall. The remaining grooves are usually filled with cement mortar first, but not much is completely flat. At this time, it is better to use it from the aspects of filling and crack resistance. Repair the plaster products to repair.

From an environmental point of view, it is recommended to try not to use gypsum that needs to be mixed with glue. This should be taken care of when choosing a product. When repairing cracks, grooving, and holes, using self-adhesive kraft paper for cracking treatment, it takes little effort, but the effect is obvious.

Third, the curing of the base layer of the wall

Generally, a curing agent is used, and in some cases, a patch (kraft paper) having a stronger curing ability is required.

The curing agent is liquid, such as various glues, concrete interface treatment agents (referred to as interface agents), and also has dry powder, which can be diluted with water, such as dry powder curing agent. In terms of environmental protection, dry powders are generally less harmful.

Patch (kraft paper) is a more advanced method of sealing, which is costly and generally does not need to be done on the wall. However, for insulated walls, loose walls, and cracked walls, the effect is more obvious and should be considered. If it has been applied (kraft paper), there is no need to make a curing agent, and the functions of the two have already coincided.

Fourth, leveling

After the wall is sealed, if the flatness of the wall exceeds 5mm, in order to make it easier to level, it is recommended to use a thick leveling material to make a thick leveling. Thick screed materials can be scraped once in a batch, try not to be too thick, to be able to level.

When the flatness of the wall is less than 5mm, the leveling material can be used for leveling. Fine leveling materials can be scraped 2-3 times in general, and should be as uniform and smooth as possible.

Wall base treatment construction price

As for the price of the wall base treatment, each area is different, generally about 15 to 20 yuan per square. Of course, there are also quotes on the Internet as low as 8 yuan / square.

The above is the construction price of the wall base treatment, the detailed answer to the construction steps of the wall base treatment, I do not know if you are satisfied with the introduction of the decoration home network Xiaobian.
