Painting the walls of the house is one of the best ways to beautify the space of the house, which brings the feeling of being clean and new. One of the common events after painting a building is that part of the wall paint is damaged and needs to be repaired. In this case, you must know how to stain and repair the painted wall so that you can fill the scratches and fading of the wall color.
The main reasons for the colors of the wall color
Before learning how to stain the wall, it is better to get to know the main reasons for the deterioration of the wall paint in order to know what causes the loss of oil paint and plastic paint on the wall and how to prevent this problem from occurring. Among the main causes of wall color deterioration, the following can be mentioned:
1- Not Cleaning Wall surface during painting:

One of the most important points for painting the walls of the building is the cleanliness of the wall surface. For this, you need to clean the surface of the wall from any dirt and dust. One of the main reasons for the plaster wall not getting painted is the dirt on the wall surface. If there is dirt, grease and dirt on the wall, the amount of adhesion of the paint on the wall will decrease and after some time, you will see peeling and separation of the paint on the wall.
2- Prime Wall Painting:
One of the most important stages of building painting is the use of primer on the wall surface. The use of primer provides a suitable substrate for the paint layer and increases the adhesion of the paint to the wall. If you do not use a primer, it is normal that the paint will not stick well on the wall and after some time you will see the paint peeling off the wall.
3- Inappropriate putty:
To paint over the old color of the wall, you need to putty to fill the cracks and seams on the wall and create a smooth surface on the wall. Correct and principled plastering removes wall defects and is like a foundation for wall paint, which preserves the paint layer on the wall. In many cases, the wrong choice of putty will ruin the color of the wall.
4- Corruption of Color:
Another reason for the deterioration of the wall color is that the paint is rotten. If you use rotten and low-quality paint, you will see the paint peeling off the wall after a while; Because the paint is rotten, it does not have good adhesion and it separates from the surface of the wall. By using high-quality paint and choosing the best building paint, the possibility of wall paint damage is much less.

5- Drying of the lower layers of color:
Too many layers of paint and the under layers of paint not drying cause the color of the wall of the house to deteriorate. Also, one of the causes of wall paint blistering is the thickness of the paint layer. After each layer of wall painting, you have to wait for the wall paint to dry and then apply the next layer of paint on the wall. If you ignore this issue and apply a new layer of paint on the wall before the previous layer of paint dries, it is normal to witness the deterioration of the wall paint.
6- Putting plastic paint on oil paint:
If you have already applied oil paint on the wall, you cannot apply plastic paint over the previous oil paint; Because the plastic paint does not have much adhesion on the oil paint and after some time it will separate from the wall. Therefore, if there was oil paint on the wall in the past, after applying the plastic paint, you will see the paint peeling off the wall of the building.

7- High Wall Humanity:
One of the most important reasons for the deterioration of the wall color is the presence of moisture on the wall. In the northern cities of Iran, due to the extreme humidity of the air, the color of the wall peels and disappears. The entry of damp and moisture into the paint layer will weaken the paint on the wall and eventually lead to the separation of the paint from the surface. For this reason, before staining and repairing the painted wall, it is better to remove the moisture from the wall so that the wall is completely dry and the new paint layer lasts longer.
