What are the correct painting methods?
1, old wall foundation treatment:
When painting the old wall, clean it up first. For wall stains, you can directly use sandpaper to polish and then brush latex paint. If the wall is dirty, all the original putty must be removed, and then the putty should be brushed again, and then the latex paint should be brushed.
2, lime sand wall directly brush latex paint to clean up the old wall:
In order to remove the dust from the old wall, it must be thoroughly removed, and then a layer of white cement is painted as a primer. Besides, for smooth surfaces, we only need to polish them.
3. Brush first:
When brushing latex paint, brush the primer first, and the primer will be used as the base. If there is no primer, it will take a long time to remove dust, mold and even discoloration from the wall.
4, lime sand wall directly brush emulsioni paint wall repair:
For the planed wall, it is very annoying if it needs to be repaired twice. If it is composed of a part, the whole wall will have obvious color difference and the appearance will be reduced, so the repair of the wall is better, preferably a complete wall. Everything has been patched.
5, color difference:
In order to avoid color difference, when using latex paint, you can choose latex paint with the same brand specifications, and make full preparations, it is best to do the whole wall at one time. As long as the original wall is painted with latex paint and the wall is smooth, you can brush latex paint directly. The color of the new latex brush can be determined according to your needs. Just prepare the roller and brush, and pay attention to it evenly when brushing. In addition, each color must be prepared in sufficient quantity, otherwise there will be chromatic aberration if the color is not enough.
