ABSTRACT:
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.
