In fact, it is not difficult to deal with cement walls. If you want to paste wallpaper, you can paste wallpaper after leveling the cement wall, but the cement wall itself is also an industrial style. If you don't want to carry out large-scale construction, you can decorate the whole space with the original ecological model of cement wall.
First, how to decorate the cement wall
The requirement of wallpaper wall is flat. The cement wall in this province is not smooth, so it needs to be sanded, and there can be no dust, small particles, cracks, holes, etc. , otherwise it will have an impact. It is best to brush a layer of basement membrane on the wall to make it smooth. First of all, do a good job at the grassroots level: level the wall with putty at the grassroots level. Next, choose a reliable quality latex paint primer. Dulux's latex paint is good, as long as it is genuine, the quality is guaranteed. Primer is usually done once. Finally, paint the wall with the base film. Then you can post your favorite wallpaper on the wall. The advantage of brushing the basement membrane is that it is convenient to change the wallpaper in the future. After the old wallpaper was torn off, the wall was intact. It can penetrate into the base surface, making the base surface more firm and durable, and at the same time, it is not affected by the base surface, moisture, moisture and alkaline substances, and will not flour the base surface.
Cement walls cannot be painted directly. Even if the wall feels smooth, if the wall is not treated, cracks, peeling and hollowing will occur after direct painting. Moreover, direct painting may not cover the background color of cement walls. Therefore, the cement wall should be brushed with interfacial agent first, then leveled to ensure the flatness of the wall is less than 4 mm, and finally the waterproof putty should be scraped twice in batches. After scraping the waterproof putty, just paint it. Putty can mask the gray color of cement.
Second, how to construct wallpaper for cement walls?
1, grassroots
If you want to put wallpaper on the concrete wall, then your base must be done well. We usually choose water-resistant putty, because only in this way can the wall cover avoid peeling and curling. The grass-roots level should be solid and smooth, without dust and trachoma. Generally speaking, we have to brush the varnish on the base for 300 years, so that there will be no leakage and flow.
2, choose the primer
Generally speaking, we often use latex paint as primer. The reason why the cement wall should be painted with a primer is because it can avoid the influence of small particles on the wallpaper.
3, coating the basement membrane
Before pasting the wallpaper on the cement wall, the basement membrane should be painted, which can not only make the wallpaper stick firmly, but also make the base layer more durable and achieve the purpose of anti-corrosion.
