A spray applied building construction coating material forms a waterproofing, water vapor permeable, air barrier, building wrap coating layer between an exterior facing surface of a building sheathing layer and an interior facing surface of an exterior building cladding layer. A building construction assembly is formed by spray coating the exterior surface of the sheathing layer with the coating material or by spray coating gaps in the sheathing layer with the coating material and spray coating the exterior surface of the sheathing layer and previously coated gaps in the sheathing layer with a second coat of the coating material and applying an exterior cladding layer over the coating layer(s). For most applications, the coating material is formulated or includes additives whereby it solidifies on the sheathing to form a coating layer that has an exterior facing, textured surface. This exterior facing, textured surface provides passages between the exterior facing surface of the coating layer and an interior facing surface of the exterior cladding layer for draining water from between and permitting air flow between the exterior facing surface of the coating layer and the interior facing surface of the exterior cladding layer.

What is claimed is: 1. A spray applied building construction coating material for forming a waterproofing, water vapor permeable, air barrier, building-wrap layer between an exterior facing surface of exterior wall sheathing and an interior facing surface of an exterior wall cladding layer and/or a
What is claimed is: 1. A spray applied building construction coating material for forming a waterproofing, water vapor permeable, air barrier, building-wrap layer between an exterior facing surface of exterior wall sheathing and an interior facing surface of an exterior wall cladding layer and/or an exterior facing surface of roof deck sheathing and an interior facing surface of an exterior roofing cladding layer, comprising: a liquid, spray-applied, oil-based elastomeric emulsion coating material means for forming a waterproofing, water vapor permeable, air barrier coating layer, which, after being spray applied to sheathing, solidifies to form a waterproofing, water vapor permeable, air barrier coating layer having an exterior portion that forms an exterior facing surface of the coating layer, an inner portion that is in contact with and adhered to the sheathing, and an intermediate portion between the exterior portion and the inner portion of the coating layer wherein the oil-based elastomeric emulsion coating material means contains tung oil for causing the exterior portion of the coating material means solidifies at a different rate than rates at which the intermediate portion and the inner portion of the coating material means solidify to form wrinkles in the exterior facing surface of the exterior portion of the coating material means and to form an exterior facing, textured surface on the coating layer for providing passages between the exterior facing surface of the coating layer and an interior facing surface of an exterior cladding layer for draining water from between and permitting air flow between the exterior facing surface of the coating layer and the interior facing surface of the exterior cladding layer. 2. The spray applied building construction coating material for forming a waterproofing, water vapor permeable, air barrier layer according to claim 1, wherein: the coating layer formed by the coating material means has an air permeability of 0.004 cfm/ft2 [0.02 l/(s·m2)] @ 75 Pa or less when the coating material means is spray applied to the exterior facing surface of the sheathing at a dry thickness of 0.12 inches and has a water vapor permeability greater than 1 perm when the coating material means is spray applied to the exterior facing surface of the sheathing at a dry thickness of up to 0.003 inches. 3. The spray applied building construction coating material for forming a waterproofing, water vapor permeable, air barrier layer according to claim 1, wherein: the coating layer formed by the coating material means has an air permeability of 0.004 cfm/ft2 [0.02 l/(s·m2)] @ 75 Pa or less when the coating material means is spray applied onto the exterior facing surface of the sheathing at a dry thickness of 0.12 inches and has a water vapor permeability of 5 perms or greater when the coating material means is spray applied onto the exterior facing surface of the sheathing at an average dry thickness of up to 0.003 inches. 4. The spray applied building construction coating material for forming a waterproofing, water vapor permeable, air barrier layer according to claim 1, wherein: the coating layer formed by the coating material means has a low emissivity of 0.30 or less to minimize solar heat absorption by the coating layer. 5. The spray applied building construction coating material for forming a waterproofing, water vapor permeable, sir barrier layer according to claim 1, wherein: the coating material means contains a termiticide. 6. The spray applied building construction coating material for fanning a waterproofing, water vapor permeable, air barrier layer according to claim 1, wherein: the coating material means contains a fungus growth-inhibiting agent. 7. The spray applied building construction coating material for forming a waterproofing, water vapor permeable, air barrier layer according to claim 1, wherein: the coating material means contains a phase change material that absorbs and releases heat within a selected temperature range.
