The shielded wallpaper 22 may be constructed during application to the wall 12, door 20, ceiling 16, or floor 14 using an on-site wet lay-up process because the resin 26 used to seal the metal-CVD coated substrate core 24 from corrosion may also act as an adhesive to secure the shielded wallpaper 22 to a wall 12, door 20, ceiling 16, or floor 14 when applied wet and allowed to dry in place. Hence, preparing on-site a shielded wallpaper 22 for connection to a wall 12, for example, comprises impregnating the metal-CVD coated substrate core with a hardening resin 26 while still wet to form an obverse layer 28 and a reverse layer 30 of the hardening resin 26, and applying the resin 26 wet shielded wallpaper 22 to the wall 12 in adhering engagement pressing the reverse layer 30 of resin 26, while still wet, against the wall 12 to dry into an adhering engagement.

FIG. 4 is a cross-section view of an exemplary embodiment of the shielded wallpaper 22 at an abutting juncture 42 with a shielding strip 44 (such as a shielding seam tape) disposed to overlay the abutting juncture 42. Again, to maintain shielding continuity, when hanging the shielded wallpaper 22 edges 36, 38 may abut so long as a shielding strip 44 covers the abutment of the edges 36, 38. The shielding strip 44 may be an elongate strip of the same configuration as the shielded wallpaper 22, as shown in FIG. 4, or any other suitable strip of shielding material that will not compromise the integrity of the shielding at the abutment.
