The wall polishing operation can be called a concealed operation, but many people think it has no meaning. Anyway, later on, paint or other materials will be used for leveling and decoration. So why bother with this extra process? In fact, this is not the case. Wall polishing has its own meaning and is a very important project. Below, we will introduce this project specifically.


Introduction to wall polishing:


1. Wall polishing is a very important step in wall decoration, aimed at improving the flatness and detail of the wall, and also an important means to create this intention. Therefore, this step cannot be ignored.


2. Whether it is day or night, when polishing the wall, in order to observe the flatness of the wall at any time, it is necessary to hold a light bulb of at least 200 watts, so as to better observe whether the flatness requirements have been met.


3. When choosing wall sandpaper, it should be noted that the thicker the better, nor the finer the better. Generally, start with fine sandpaper and replace it with coarse sandpaper if it cannot be touched. However, it is generally necessary to use fine sandpaper to re polish the wall to ensure that it is detailed and free of scratches.


4. Generally, good decoration companies recommend owners to choose waterproof putty in order to improve the service life of the walls in their homes. This type of putty can be time-consuming and laborious to polish, and some unreliable decoration companies may refuse to use waterproof putty for various reasons, completely disregarding the owner's consideration. Therefore, owners should pay attention to the selection of putty.


5. The polishing performance of putty has been mentioned in the inspection report, among which the "polishing performance" item is tested one day after the putty is scraped. Generally, water resistant putty is polished within three days after being applied to the wall. At this time, the strength is relatively low and the external structure is not yet sturdy, making polishing more labor-intensive.


6. Generally, after 7 days, the putty will return to me and dry completely. At this time, the putty's adhesion will be relatively strong, the surface structure will be relatively strong, and it will be relatively difficult to polish. In order to achieve better polishing effect, it should be first polished with 120 grit coarse sandpaper, and then polished with 360 grit or more fine sandpaper for a second time, which will make the polishing more thorough.


7. The bonding strength of putty directly determines its future service life and water resistance. When conditions permit, using water resistant putty with higher bonding strength has a higher long-term cost-effectiveness.


The above is an introduction to the meaning of wall polishing. I believe that after reading the above content, we will only have a better understanding of this aspect. Do not underestimate the small details of wall polishing, which are related to the subsequent construction process and various factors such as beauty and application. Therefore, we cannot underestimate it.
