Cornice Adhesive may also be used for bonding other plaster decorative products, back-blocking plasterboard joints and laminating plasterboard sheets. Knauf's cornice adhesive mixes easily to a creamy, lump-free gauge and has excellent wet tack. This high-strength product is ideal for use on new and existing plasterboard work, including heavy-duty internal/external corners.
