After cracking, how should we prevent the crack from continuing to extend and repair? After the table is cracked, a round hole drill should be used at the top of the crack extension direction to prevent the table from continuing to crack. Repairing should be done by professionals. First, the cracks need to be embedded; then the glue is prepared and poured into the embedded seam; after the glue is completely cured, it is polished. However, there will be traces after repairing the quartz stone, which has a certain impact on the overall aesthetics.
