1. What are the steps for scraping second-hand houses?
The steps of scraping second-hand houses include:
(1) First of all, remove the latex paint and white on the original wall surface and clean the wall surface.
(2) Then scrape or roll coat the interface agent for the first time on the wall. The interface agent can make the wall surface no longer "slag off" and seal the cement layer at the bottom of the wall surface to form a sealing film, thus ensuring the construction quality of scraping and forming a better sealing bottom layer.
(3) Then scrape gypsum for leveling. Plaster scraping can fill the cracks in the wall, make the cracks no longer expand, and have sufficient supporting force.
(4) Then paste patches, bandages and kraft paper.
(5) Then scrape the white for the first time. After scraping, let the wall dry naturally.
(6) Then scrape it for the second time. The second kind of white can make the wall smoother.
(7) Then polish the wall to create flatness. After scraping for the second time, you can polish the wall in a large area. You can use a 200-watt light bulb to shine on the wall, so that you can see the traces of trowel on the wall and then polish it with sandpaper.
(8) Then carry out indoor cleaning and protective treatment. Because the construction of polishing the wall will make the room full of dust, it is impossible to paint directly. Therefore, it is necessary to clean up the walls and floors first, and then remove the dust that has been polished indoors before painting construction can be carried out.
Second, what should I pay attention to in the wall decoration of second-hand houses?
1, check how the original wall materials were preserved. If most of the putty layer has been damaged, it is necessary to remove all the putty layers and scrape the putty again. If the putty layer is not badly damaged, then the wall surface does not need to be completely eradicated, only the parts that need to be repaired need to be repaired.
2, brush * * * in two steps, the first step is to brush the primer, it is best to brush twice. When the primer is dry, you can apply the top coat. Topcoat is particularly important for the overall beauty of the wall. Therefore, when choosing paint, we must choose paint with uniform color to avoid the color difference of wall paint and affect the overall aesthetic effect of the wall.
The above is a detailed introduction about the steps of scraping the wall of the second-hand house and the matters needing attention in the wall decoration of the second-hand house, hoping to provide some help to everyone. Second-hand housing decoration must not be taken lightly, because once the decoration is unqualified, it will be difficult to move in, so we must be cautious.
