Engineered quartz stone slab not only has the characteristics of natural stone with rich colors and beautiful surface but also has the characteristics of antibacterial, high-temperature resistance, wear resistance, anti-leakage, non-toxic, non-radiation, and so on. It is used by more and more people in modern home decoration. Recognized. However, in specific applications, it is inevitable to splice two pieces or even multiple pieces. After splicing, in order to make the whole look integrated, it is inevitable to polish the splicing seams and the periphery. However, whitening will occur at the splicing joints that have been polished, and the darker the sheet, the more serious the whitening will be after polishing.

What causes the whitening of the seams?

The surface of the quartz stone plate is as mirror-like. This is because the quartz stone manufacturer has a water polishing process in the production. Water grinding polishing is the result of high-pressure and high-speed grinding with multiple 2000-mesh water grinding heads, which is beyond the reach of other hand-held tools. The whitening phenomenon occurs after being polished by an angle grinder because the substrate of the quartz stone plate is white. During the joint polishing process, the gloss and color of the surface of the plate are destroyed, and the white substrate is exposed. This is why the plate The darker the color, the more obvious the cause of whitening at the seams.

How to solve the whitening phenomenon? This is a problem we all care about!

1. Waxing and varnishing can be used, but these two methods cannot be solved for a long time, only temporarily relieved.

2. Use brightener or resin to repair. After repairing 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 connection, you should find a professional, try to avoid secondary grinding and polishing during the installation process of the plate, and the joint should be treated carefully during installation to achieve seamless connection. There is also preventive work to avoid unnecessary secondary polishing caused by the exposure of the glue during docking.
