<p>A multi-layer article (40) that includes a layer of a water-soluble polymer that provides a water-removable, non tacky film (34) over an adhesive layer and/or acts as an adhesive for securing the multi-layer article to a substrate, such as concrete, when wetted. The article forms a water barrier capable of being secured to an area of potential water flow including a layer of flexible, water-impermeable sheet material having a layer of adhesive coated thereover, and a continuous or discontinuous coating of a water-soluble polymer thereon. When the water-soluble polymer is wetted to at least partially solubilize the water-soluble coating, the polymer and/or the underlying adhesive layer readily adheres the article to a substrate at the area of potential water flow. In a preferred embodiment, the flexible sheet material includes a layer of adhesive (tacky material) and the adhesive layer is coated with the layer of water-soluble polymer to eliminate the necessity of using a sheet of release paper to prevent the adhesive layer from adhering to itself, when in roll form, and during handling and installation. <IMAGE></p> |
