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.

I claim: 1. A system for sealing the space between exterior wall panels, said system comprising: A mastic placed in the space between the exterior wall panels and coating a portion of the exterior surface of the exterior wall panels; A single, semi-rigid, PVC composite fiber, perforated foundation
I claim: 1. A system for sealing the space between exterior wall panels, said system comprising: A mastic placed in the space between the exterior wall panels and coating a portion of the exterior surface of the exterior wall panels; A single, semi-rigid, PVC composite fiber, perforated foundation tape, having a length and width, placed over and within the extents of said applied mastic; Wherein said perforations allow the underlying mastic to flow through the semi-rigid, PVC composite fiber, perforated foundation tape when pressure is applied thereon; A first mastic layer placed over and extending beyond the width of said single, semi-rigid, PVC composite fiber, perforated foundation tape; An elastomeric, sealing finish tape having a width greater than said single, semi-rigid, PVC composite fiber, perforated foundation tape placed over said first mastic layer; and A second mastic layer placed over and extending beyond the extents of said elastomeric, sealing finish tape. 2. The system as defined in claim 1 wherein the ratio of the width of said elastomeric, sealing finish tape to said semi-rigid, PVC composite fiber, perforated foundation tape is about 2:1. 3. The system as defined in claim 1 wherein said mastic is an elastomeric acrylic sealant. 4. The system as defined in claim 1 wherein said semi-rigid, PVC composite fiber, perforated foundation tape further includes fibers glued to the exterior surface thereof. 5. The system as defined in claim 1 wherein said elastomeric, sealing finish tape is selected from a group including: fabric, film, or a mesh/mat. 6. A method for sealing the space between exterior wall panels, said method comprising the steps of: Filling the space between the exterior wall panels and coating a portion of the exterior surface of the exterior wall panels with mastic; Placing a single, semi-rigid, PVC composite fiber, perforated foundation tape, having a length and width, over and within the extents of said applied mastic; Wherein said perforations allow the underlying mastic to flow through the semi-rigid, PVC composite fiber, perforated foundation tape when pressure is applied thereon; Covering said single, semi-rigid, PVC composite fiber, perforated foundation tape with a first mastic layer, wherein the mastic layer extends beyond the width of said foundation tape; Placing an elastomeric, sealing finish tape having a width greater than said single, semi-rigid, PVC composite fiber, perforated foundation tape over said first mastic layer; Covering said elastomeric, sealing finish tape with a second mastic layer wherein said second mastic layer extends beyond the extents of said finish tape. 7. The method as defined in claim 6 wherein the ratio of the width of said elastomeric, sealing finish tape to said semi-rigid, PVC composite fiber, perforated foundation tape is about 2:1. 8. The method as defined in claim 6 wherein said mastic is an elastomeric acrylic sealant. 9. The method as defined in claim 6 wherein said semi-rigid, PVC composite fiber, perforated foundation tape further includes fibers glued to the exterior surface thereof. 10. The method as defined in claim 6 wherein said elastomeric, sealing finish tape is selected from a group including: fabric, film, or a mesh/mat. 11. A two-layer tape for use over the space between exterior wall channels wherein the space between the exterior wall panels has been filled with and the surface of the panels has been covered with a mastic, said two-layer tape comprising: A single, semi-rigid, PVC composite fiber, perforated foundation tape layer, having a length and width; An elastomeric, sealing finish tape layer having a length and width, wherein said width of said elastomeric, sealing finish tape being greater than the width of said single, semi-rigid, PVC composite fiber, perforated foundation tape layer; Wherein said elastomeric, sealing finish tape layer is laid over and attached to said single, semi-rigid, PVC composite fiber, perforated foundation tape layer such that the length dimensions of each layer are substantially parallel to one another; Whereby when said two-layer tape is placed over the mastic filling the space between and covering the surface of the exterior wall panels, the mastic will pass through the perforations in said single, semi-rigid, PVC composite fiber, perforated foundation tape layer and contact the overlying elastomeric, sealing finish tape layer.
