Abstract This invention is a floor covering which may be easily removed from its underlying surface and which resists buckling or folding when rolled, comprising: (a) a facing layer; (b) a bottommost release backing layer which comprises a non-woven fabric of relatively short fibers, and (c) a polymer layer which is bonded to the release backing layer on one side and directly or indirectly to the facing layer on the other side. In another aspect, this invention is an improvement in a process for preparing a polymer-backed floor covering, which process comprises applying a layer of an uncured polymer-forming composition to one side of a textile and curing said composition to form a 35,311-F polymer backing attached to said textile, the improvement which comprises applying a layer of a non- woven fabric of relatively short fibers or continuous filament fibers to the polymer backing before said polymer-forming composition is cured to a tack-free state. 35,311-F
