First of all, please do a good job of batch putty and latex paint painting. You can't draw until these are done! Otherwise, painting directly on the exposed concrete wall is really hard to see, and no one has tried to do so.

But what about painting with pigments? I suggest choosing wall painting or wall stickers or wallpaper, but in terms of cost, wall painting is relatively high. If you choose wallpaper or wall stickers, it is both beautiful and cheap. After using it for a period of time, you can change it according to your mood (for wall stickers). But if environmental protection and simplicity are considered, diatom mud is better. Diatom mud can remove impurities in the air, purify the air, release negative ions and absorb static electricity. Of course, it is also very environmentally friendly.

It is completely possible to paint the cement surface, but the biggest problem is to consider the smoothness of the surface and whether there is a potential crack threat.

1. If the cement surface is not smooth enough, you can use cement and coat it with a smooth surface. It's better to leave it to professional experts and make it difficult for you to handle it yourself.

If you don't know if your cement surface is in danger of cracking, you can try that one and bake it with a lighter for three to five minutes. Immediately put a piece of ice on it and observe it after the same time. If there are micro cracks, don't draw them. If there are no cracks, there should be no big problem. If it is self-painted cement coating, pay attention to the use of ordinary cement. The construction temperature should be controlled at about 20℃, too high or too low, and cracks will occasionally appear, which will affect the picture effect.

The selected coating is wall finish. If it is an exterior wall, it is best to use exterior wall paint, which can increase the service life and maintain the aesthetic feeling of the picture for a long time.
