No matter how fine the cement wall is made, it will not stick to the wallpaper, and even if it is barely stuck, it will fall off. The seams of wallpaper will be very obvious, the visual effect will be very bad, and cracks and falls off will often occur.

So how can the cement wall be decorated to paste wallpaper? The requirement of wallpaper wall is flat. The cement wall itself is not smooth, so it needs to be sanded, and there can be no dust, small particles, cracks, holes, etc. , otherwise it will affect. It is best to brush a layer of basement membrane on the wall to make it smooth. First of all, we should do a good job of grassroots treatment: use putty to smooth the grassroots of the wall. Then choose a good quality latex paint primer, (choose this one yourself, the quality is good,) one primer per class is enough. Finally, brush the wallpaper basement membrane. After that, you can put your favorite wallpaper on the wall.

Note: Cement walls cannot be painted directly, even if the walls feel smooth. If the wall is not treated and painted directly, there will be cracks, peeling and hollowing in the future. Moreover, direct brushing on the cement wall may not cover the background color, so it is necessary to brush the interface agent on the cement wall first, then level and confirm that the flatness of the wall is less than 4 mm, and finally scrape the waterproof putty twice before brushing the paint.
