First, a small part of the wall skin can be repaired with toothpaste.
First of all, we need to apply toothpaste to the peeling part of the wall, then spread the toothpaste evenly with a ruler or something, and wait a while. After the toothpaste dries, we will find that the wall is brand new, just like before peeling, which saves our cost.
Second, a small part of the wall skin falls off, and materials can also be replenished in a local scope.
Local peeling on the wall, we need to scrape off the peeling part, and then scrape putty on a small scale. If the wall is peeling on a large area, we need to remove the whole wall and then scrape putty.
Third, most of the walls are peeling.
The large-scale peeling of the wall surface may be caused by the problem of the wall base. At this time, we need to rebuild. The new construction needs to strengthen the base, then smooth it with gypsum, stick a grid cloth, then brush a layer of primer and finally paint.
Fourth, a small part of the walls peeled off and cracks appeared.
The wall is just peeling, without white powder and falling off. We can directly use paint to make up the brush, which is very convenient for construction.
Fifth, the wall peeling is very serious.
If there is a problem with the wall skin base, we can also choose to tear down the old wall and install a new wall, so that we can redecorate the wall.
Methods of preventing wall skin from falling off
First, do a good job in grassroots governance.
When we decorate the wall, we will shovel off the putty layer on the wall and do the basic treatment again.
Second, if the wall is empty or cracked, it should be dealt with seriously.
If there are holes or cracks in the wall, we need to knock out the holes and fill them with cement. If there are cracks, we can fill them, which can prevent the wall from falling off and facilitate the subsequent treatment.
