In the rough room decoration, the first step is generally to carefully decorate the wall. So, how to shovel the wall? What should we pay attention to in the construction of wall covering? Next, let's talk about how to shovel the wall skin of the blank room and how to apply putty to the blank room. If you are interested, you can have a look and hope to help.
Many people will ask, if the new house has a layer of putty when it is handed over, do you need to shovel the wall? First of all, determine whether the wall is water-resistant putty. If it is water-resistant putty, it is not necessary to remove the original wall putty. If the non water-resistant putty needs to be removed, how to identify whether it is water-resistant putty? Use a broom to gently sweep the wall. If the powder is obviously removed, it means that it is a non water resistant putty with poor adhesion. The putty must be removed and redone. Use mineral water to sprinkle water on the wall. The water will not flow down. It will be quickly immersed in the putty, indicating that it is a non water resistant putty, which must be removed. If the wall surface is watered, gently rub the wall surface with hands to remove the obvious looseness.
Secondly, the reason to determine whether the wall putty is removed is that there is obvious hollowing between the putty layer and the original wall structure layer. Inspection method: firstly, there is obvious bulge on the viewing surface. If there is obvious bulge, the putty on the top of the original wall needs to be removed; secondly, use a small hammer to knock, and there is a bump of empty drum, indicating that the putty or gypsum leveling layer below the putty is empty, and the original wall grease needs to be removed.
There are two layers on the surface of the wall or top structural plate, one is the plastering gypsum for leveling, and the other is the putty layer. If it needs to be removed, the two layers shall be completely removed to the cement mortar layer, and no partial mortar layer shall be left, so as to prevent the hollowing caused by the construction on the falling mortar layer.
The above is the method that small make-up brings for everybody to wipe out wall skin to scrape putty, hope to have the help that decorates to the home!
