Abstract: A laminated wall structure, suitable for use in an exterior insulation finish system, comprises the following layers in the order provided: i) a layer of building sheathing; ii) a layer of water-resistant adhesive which substantially completely covers and adheres to said building sheathing; and iii) a layer of thermal insulation adhered to said building sheathing by said water-resistant adhesive. The laminated wall structure, which can be used with all conventional building sheathings, can require less time to construct than known structures.

Abstract: A polymeric composition including: (1) an addition polymer including at least 20 wt %, based on dry addition polymer weight, copolymerized vinyl ester monomer, (2) a protective colloid, and (3) 0.1 to 3.0 wt %, based on dry composition weight, olefin/maleic anhydride copolymer having an olefin/maleic anhydride molar ratio of 30/70 to 70/30, the composition in pulverulent or aqueous form, the composition optionally including a hydraulic substance such as cement. The invention also relates to a method for improving the water resistance of a dry or cured composition by using the composition.
