ABSTRACT:
An integrated moisture/air barrier system that serves to mitigate the penetration of water and air around or through various types of exterior wall building sheathing products such as plywood, OSB, gypsum board, cement board, rigid foam boards and foil-faced composition products. The moisture/air barrier surface is preferably installed as a step in the manufacturing process for certain types of sheathing such as wood or gypsum-based products. However, it may also be installed in-situ in instances where the pre-coated units are not readily available or the factory surface needs to be supplemented at joints or terminations. The material used in forming the moisture barrier is urethane or urethane/silicone that is sprayed, squeegeed, applied by brush or roller and includes additives to aid the coating's workability and retard the growth of mold/fungi. The urethane and/or urethane/silicone coating is readily compatible with various known sheet flashing materials and common construction materials and readily bonds thereto.
