Quartz stone is made of 92% quartz sand powder as the main aggregate, 8% resin, pigment, and other auxiliary materials as the main binding material. After mixing, it is made by vacuum pressure vibration molding, curing, and polishing.



  Due to its high density and high hardness, quartz stone has excellent scratch resistance and stain resistance. It is not scratched, impermeable, stain-resistant, corrosion-resistant, high temperature resistant, green and environmentally friendly, and can be in direct contact with food.


However, from a physics point of view, quartzite has slight thermal expansion and contraction and has certain mechanical properties such as shrinkage stress, impact toughness, and elongation at break. When the material cannot withstand the internal stress brought by thermal expansion and contraction And cracking occurs when subjected to severe external impact.

Quartz stone countertop cracking situation and causes


   1. Cracking in the central part of the quartz countertops, etc.: subject to high temperature, impact by an external force, uneven cabinet or backing plate, internal damage to the plate, etc.


   2. Cracking at the corner: too tight against the wall without shrinkage joints, uneven or uneven padding between the two cabinets, cracking due to external impact or uneven temperature shrinkage of the countertop and cracking


   3. Cracking around the countertop basin: There is no gap between the countertop basin and the basin hole, the basin hole is not polished and smooth, and it is cracked due to external force impact or uneven temperature contraction of the countertop and cracking


   4. Cracking around the furnace hole: there is no gap between the gas stove and the furnace hole, the furnace hole is not polished smoothly, the surface is cracked unevenly due to external force impact or temperature change, and the crack is uneven


   5. Cracks in the rear water blocking: the cabinet is not flat or the pad is not flat


  6. Cracking at the connecting part of the back water-stop: the glue is not firmly bonded


7. Cracking at the splicing seam of the countertop: when the installer is splicing, the seam is not aligned, the glue is not evenly coated, or the curing agent is added to the glue or excessive agent is added to make the seam more brittle and cracked when it is slightly impacted during use .
