Why is there a glue-like residue on the edges of marble and granite slabs?
A coat of epoxy resin is either rolled on by hand or applied by high tech machinery, then heated to harden. The slabs are then sent through a series of diamond and synthetic abrasive lines that remove 99% of the resin, leaving a highly polished product virtually free of defects. This enables consumers to have colors of stone not available in years past, as well as a product unmatched by man-made solid surface products.
