A decorative laminate assembly having, in descending superimposed relationship, a decorative layer, an impregnated tie sheet and a substrate. Preferably, the laminate assembly also includes an overlay layer on top of the decorative layer, and the substrate preferably contains FRP. The tie sheet is preferably impregnated with a bridging agent having a mixture of MEK, an acrylic ester, a polyester and an organic peroxide. Surprisingly, it has been discovered that impregnated tie sheet of the present invention not only bonds remarkably well to the melamine resin treated (or untreated) decorative layer, but also simultaneously bonds extremely well to an FRP substrate. The decorative laminate assemblies of the present invention can be used for a variety of purposes, including wall panels and flooring applications. When the present invention is used for flooring applications, it is preferred that the overlay layer has enhanced wear resistant qualities. The chemical mixture of the bridging agent used in the tie sheet can also be used without any sheet and can be instead deposited directly between two incompatible layers of a laminate.
