Seams are created by joining two pieces of granite together with a knife grade epoxy that is color-matched to the background tone of the granite countertops. Suction cups and seamers are then used to tightly join the pieces together. Any excess bonding material is then cleaned off the surface with razors to leave a smooth and sleek bead of epoxy between both pieces. Occasionally, in areas where expansion and contraction are predominant, the use of silicone replaces the epoxy.
