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.
Claims16
A floor surface comprising at least one layer of cementitious material bearing a layer of a cover composition comprising a polymeric binder and magnetic and/or magnetizable particles, the layer of the cover composition having a thickness of 0.15 to 5 mm, and wherein the polymeric binder is prepared from a precursor composition comprising at least a polyisocyanate component and an amine-group containing component, wherein the magnetic and/or magnetizable particles are iron-nickel oxides, ferrosilicones, or combinations thereof, and the layer of the cover composition has a water vapor transmission rate of at least 0.25 g h−1 m−2 and up to 0.711 g h−1 m−2 according to ASTM D1653 test method B, wherein said floor surface further comprises a finish floor covering applied over and fixed by means of magnetic interaction to said layer of said cover composition.
A floor surface comprising at least one layer of cementitious material bearing a layer of a cover composition comprising a polymeric binder and magnetic and/or magnetizable particles, the layer of the cover composition having a thickness of 0.15 to 5 mm, and wherein the polymeric binder is prepared from a precursor composition comprising at least a polyisocyanate component and an amine-group containing component, wherein the magnetic and/or magnetizable particles are iron-nickel oxides, and the layer of the cover composition has a water vapor transmission rate of at least 0.25 g h−1 m−2 and up to 0.711 g h−1 m−2 according to ASTM D1653 test method B, wherein said floor surface further comprises a finish floor covering applied over and fixed by means of magnetic interaction to said layer of said cover composition.
