How do I need to make up for the falling wall? 100

Redone walls. Redoing the walls is the most straightforward way to do this. However, this method is only suitable for those who have serious wall detachment.

First of all, we must remove the parts of the original wall that have fallen off and remove them to the base layer of the wall. Then repaint and reapply latex paint.

Peel off the walls.

This method is suitable for small areas where the wall surface is falling off. We can use a putty knife to shovel off the batch of ash on the wall. Then use a small roller to paint the wall and wait for it to dry.

Make a layer of drape. Add an appropriate amount of white glue to the water, stir with putty powder, and drape it on the interface agent coating with a batch knife, draped and flattened, because it is a road that does not need to be too required to be smooth with the original good wall around it, but it cannot protrude from the original good wall and dry it naturally.

Frosted paper to smooth the wall.

We can also use sandpaper sanding to smooth out the part of the wall that has fallen off. This method still requires a certain amount of skill. When we are sanding the wall, remember not to sand it in large areas.

First is a certain position, and then it is sanded in a certain direction. It will look better that way.

This kind of wall is caused by water seepage, first of all, deal with the water seepage, and then paint it with anti-cracking mortar, and then use putty to batch it, you can brush white ash and porcelain powder.

If the wall falls in a small area, it needs to be filled with simple white ash, if it is a large area of falling, the entire wall ash will be stripped off and the wall will be repainted.

Let's first look at the specific situation of the wall falling off. Generally speaking, the wall peeling is divided into latex paint surface peeling and cement wall peeling. If it belongs to the first type, you need to re-apply the bottom layer, scrape the porcelain powder, and then repair the peeling part with the best brand wall paint.

It is more troublesome to repair the second type, because this kind of falling off is caused by the proportion of cement on the cement wall is too small, and the bottom layer of the original wall needs to be shoveled off and then painted. After the walls are completely dry, the first set of schemes can be carried out. Reasons for this:

1. The cleaning of the base layer is not clean or improperly handled, which makes the quality of the wall a big problem, and the problem will be exposed after a long time. 2. If the quality of the mortar and raw materials prepared for wall repair is not up to standard or the use method is improper, it will lead to the problem of a large area of the wall falling off. 3. If the numerical deviation of the base layer is large, such as the one-time plastering is too thick and heavy, and the dry shrinkage rate is large, it will cause problems.

4. If the plug ash on both sides of the door and window frame is not tight or the embedded parts of the wall do not meet the standard requirements, it will lead to cracks and hollowing in the position of the door and window frame. 5. If the mortar used to repair the wall is not used up in time after stirring, and it is parked for a long time, the raw materials of the wall will not be tightly bonded together in the later stage, and it will naturally fall off.

1. When the peeling phenomenon occurs on the wall, and the peeling area is relatively large, the peeling position should be removed first, until the base position, and then sandpaper is used to polish the wall to keep the wall flat, and then a layer of interface agent should be painted on the wall. 2. When the interface agent is dried, then use gypsum to level the wall, in order to effectively avoid the phenomenon of peeling off the wall again, it is also necessary to hang a mesh cloth on the wall, so as to strengthen and prevent cracking. After the mesh cloth is pasted, it is also necessary to scrape putty on the wall.

Related information: 1. First of all, the choice of materials is the most important, and we must choose high-quality materials. If the selection of construction materials is not up to standard at the beginning, it will be very troublesome to use later.

Because the wall is prone to some problems, it is necessary to buy high-quality products from regular channels and choose qualified products, especially putty powder, paint, wall materials, etc. 2. When painting the wall, you must do a good job of priming first, which is like a girl's makeup. Therefore, it is also very important to use coarse sandpaper to polish the wall first to ensure that the wall can be kept flat and will not appear hollow, cracking, etc., so as to lay a good foundation for the later wall construction.

In two cases, if only the paint layer of the wall falls off, it is necessary to remove all the paint layer, and after the wall base layer is cleaned, the putty is re-brushed and finally painted. The cement layer on the wall is peeling off, which requires all the peeling areas to be removed and the holes clean to ensure that there are no hollows. Then, use solid wall adhesive to coat the group to achieve the purpose of reinforcing the base layer.

After the treatment of the base layer of the wall, mix some cement with 108 glue to pull the wall surface, and then use solid wall glue and cement Huang Chatan dry sand to mix these materials evenly and paint, and finally wait for the cement to dry through.

Causes of wall falling off:

1. The peeling off of the paint layer is generally caused by the reduction of the process during construction and the influence of environmental humidity, which are more common. For example, putty and paint are brushed less, room leakage, etc., generally appear in toilets and bathrooms. Of course, there are many other reasons, such as the relatively long age of the renovation, the use of inferior decoration materials, and so on.

2. The reasons for the fall off of the cement layer of the wall are more complicated, the ratio of cement and auxiliary materials is problematic, the temperature is low during construction, the number of cement is not enough, the cement is placed for a long time after mixing, it is not used, and the cement is not evenly smeared during the construction process, which will lead to the phenomenon of cracking and falling off of the cement layer of the wall after construction.
