With the improvement of the production capacity and technology of quartz stone manufacturers, the price of quartz stone is becoming more and more affordable, and more people begin to choose prefab quartz countertops as the main decoration materials, such as floor laying, wall dry hanging and modeling production. However, countertops are the most widely used, but manufacturers and processors have always been troubled by the phenomenon of cracking of countertops after installation.

We should first understand the cause and location of the crack. Prefab quartz countertops is a brittle polymer composite material, which has the characteristics of thermal expansion and contraction. It has certain shrinkage stress, impact toughness, elongation at break, etc. When the material cannot bear the internal stress caused by thermal Cracking occurs in the event of severe external impact. The cracking position is generally the edge cracking extending inward or the cracking around the opening.

After cracking, how should we prevent the crack from continuing to extend and repair? After the countertop is cracked, a round hole drill should be used to drill the top of the crack extension direction to prevent the countertop from continuing to crack. The repair should be performed by a professional. First, the crack needs to be embedded; then the glue is prepared and poured into the embedded seam; after the glue is cured, it is polished. However, there will be traces after the quartz stone is repaired, which will have a certain impact on the overall aesthetics.
