Wall polishing is a very important part of wall decoration, and it is an important means to improve the flatness, detail and final effect of the wall. Whether it is day or night, when polishing the wall, in order to be able to observe the flatness of the wall at any time, be sure to hold a bulb of at least 200 watts. At the same time, the choice of wall sandpaper is not as thick as possible. It is not as fine as possible. Generally, it starts with fine sandpaper and tries to change the sandpaper. But in the end, it is usually re-polished with fine sandpaper. To ensure that the wall is meticulous and scratch-free. In order to improve the service life of the owner's wall, a good decoration worker will recommend the use of water-resistant putty, even if it is slightly difficult to polish. In addition, the water-resistant putty is best polished within 3 days after the upper wall, at this time the strength is low, the surface structure is not firm, and it is more labor-saving to polish. In order to achieve better results, you can first polish the first pass with 120 mesh coarse sandpaper, and then polish the second pass with fine sandpaper of 360 mesh or more. The bonding strength of the putty directly determines the future service life and water resistance. When conditions permit, the long-term cost performance of the water-resistant putty with higher bonding strength is higher.
