While fixing polished stones, huge granite or marble slabs, synthetic marble or granite slabs to the vertical surfaces, normal adhesives do not hold their weight, as these stones are too heavy and have a closed grained surface which is smooth. For this reason such slabs are either mechanically fixed with anchor fasteners or a mechanical key is created on the rear surface of the slabs, so that a general purpose adhesive can be used. Perma Stone Adhesive is used for creating mechanical key on the stone surfaces.
