Each butcher block table is comprised of ¾” x 1½” wood blocks clamped together with superior Tite Bond 3, a waterproof wood glue. Each block is clamped together on the face grain as opposed to the end grain to promote stability and prevent cupping and bowing. The finish is an acrylic catalyzed polyurethane finish, ICA, in customer’s choice of matte or satin and is heat, scratch and moisture resistant. Our finish is also FDA approved for indirect food contact.
