Abstract: An improved two-layer tape for covering the joint between exterior building panels includes a single, semi-rigid, polymer composite foundation tape a plurality of perforations formed therethrough and a flexible, resilient two-component mesh finish tape adhered to the foundation tape in substantially parallel relation along their lengths. The mesh finish tape, which is a two-component reinforced strand mesh having a width greater than the width of the foundation tape, has openings formed therethrough such that when said two-layer tape is bedded in adhesive covering the joint between adjacent exterior building panels, the adhesive will pass through the plurality of perforations in the polymer composite foundation tape and the openings in the mesh finish tape. The two-layer tape can be incorporated in a two-layer tape core joint treatment system and employed in a method of covering the joint.

Abstract: Buildings and walls are commonly constructed with exterior walls composed of specially treated engineered wood panels, cement panels, fiber cement panels, glass-matt-faced gypsum panels, and gypsum/cellulose sheathing panels. The spaces or edges between these exterior panels are sealed using the disclosed dual-tape-core joint treatment system and method of the present invention. After curing, a color matching acrylic-epoxy scratch coat or elastomeric primer followed by a textured finish coat is sprayed, brushed or rolled on the exterior panels.
