Leaving a gap in a large area of stone can effectively avoid the problems of uneven installation and poor impression caused by non-verticality in stone field construction.
It can effectively alleviate the color difference collision problem of stone itself. The color difference will be reduced after the seam is left, and it is not obvious as the tight seam.
It can effectively avoid defects such as bumps and cutting errors caused by various reasons, and bumps with small corners will not be so obvious after leaving seams.
