3. If the lime wall has not been painted for more than half a year, add acidic color drywall powder, if green, sky blue and other colors, it is easy to produce neutralization and overcoloring, so you need to pay attention. When painting the wall by yourself, pay attention to the safety of the operation.

After looking at the steps of painting the wall introduced above, people should have a lot of understanding of the matters of wall painting, please ask professional personnel to paint, so that it can have a good effect, and the precautions for painting the wall are also very much, when you see the above text to give you an introduction, you will know a lot about this knowledge.

What are the tips for painting the wall: The first point: Before you are ready to paint the wall, you must first make sure that the outer layer of lime on the wall you are going to paint has been completely dried, because painting the wall that is not dry will make the wall appear spotted, which will affect the appearance of the beauty.

The second point: in the process of painting the wall, we must constantly stir the lime slurry, otherwise the stucco will be brushed out of different shades of stripes due to the solidification of the lime slurry, which is very unsightly. The third point:

Painting has directions and requirements, random painting will only make the wall very irregular, as if scribbling an impression painting on the wall, very unbeautiful, so if you want a clean and beautiful wall, you have to paint vertically, from top to bottom, if it is a horizontal brush, you can only brush from left to right, but you must deal with the amount of lime slurry controlled by the brush to prevent the lime slurry from flowing down and forming an imprint. The fourth point: if the old wall is painted with new whitewash, it means that there is likely to be old dark lime on the wall, or because of the long time, there are a lot of spots on the wall, if you want to refresh the color, you must first brush the wall with white lime slurry, and then you can powder the refreshed color after drying.

The fifth point: If the wall has not been painted for more than half a year, and you want to paint acidic colored drywall powder, such as the more popular green or blue, it will be easy to have an acid-base neutralization reaction with the original powder, so you must do a good job of investigation before painting, so as not to waste your previous efforts and add new trouble. Sixth point:

If you ask a worker to paint, you must hire an experienced worker to prevent the waste of time caused by greed for cheapness, and on the other hand, if you want to paint by yourself, you must be prepared in terms of safety. This answer applies to wall painting in most cases.
