Abstract: A method of creating a magnetically adhered, static dissipative floor covering (1). The method comprises the steps of providing a magnetically receptive floor surface (3), and supplying a floor covering comprising a plurality of static dissipative, magnetic floor tiles (4). The tiles (4) are held in place by magnetic interaction between the tiles (4) and the magnetically receptive surface (3). The floor tiles (4) are of composite construction comprising a) a static dissipative vinyl wearing layer (5), b) an integral, conductive ground plane (6) and c) an integral, planar magnetic layer (7), The conductive ground plane (6) comprises a non-woven synthetic fabric (8) with a nickel-copper coating and a conductive adhesive backing (9). The conductive ground plane (6) is bonded to the static dissipative wearing layer (5) by the conductive adhesive backing (9).
Abstract: The present invention is directed to a method for providing a surface, in particular a floor surface, with a layer of a magnetic and/or magnetizable cover composition, the surface having at least one layer of cementitious material, wherein the method comprises the step of spreading the layer of the cover composition onto the surface, the cover composition comprising a polymeric binder and magnetic and/or magnetizable particles, characterized in that the layer of the cover composition has a water vapor transmission rate of at least 0.25 g h?1 m?2 according to ASTM D1653, and the surface and/or the layer of cementitious material has a relative humidity of more than 75% according to ASTM F 2170-11.
