With the continuous increase of my country's quartz stone manufacturers and the continuous improvement of production technology, quartz stone plates have entered the mass consumption. At present, the most used field is cabinet countertops, which are called quartz stone countertops. Due to the high hardness of quartz stone, it brings certain difficulties to the processing, because the processing of quartz stone is different from the processing of ordinary artificial stone, especially the splicing. The common problem in the splicing of quartz stone is that the two plates appear high and low, and the treatment method is often polished, which will cause the surface of the plate to lose luster. Then, how to repair the tarnished quartz stone? Next, we talk to FABULOUS Group Editor Take a look.

　　Common repair methods after discoloration due to sanding are:

　　1. It can be waxed or varnished, but these two methods cannot be solved for a long time and can only be temporarily relieved.

　　2. Use brightener or resin to repair. After repairing with this method, it can be maintained for a long time but cannot be eradicated. If you want to fundamentally solve the whitening phenomenon of the joints, you should find professionals to avoid secondary grinding and polishing during the installation of the plates. The joints of the plates should be carefully treated during installation to achieve seamless joints. There is also preventive work to avoid unnecessary secondary polishing caused by the exposed bumps of the glue during docking.

　　The surface of the quartz stone plate is not processed by a special method, but is made by more than 30 high-pressure rapid water grinding. Once it is polished at a low speed, it will cause whitening and discoloration. Therefore, the two plates must be kept in a horizontal line during processing and installation.
