Abstract
Abstract The surface of a covering which is to face a floor is at least in part constituted by an adhesive capable of forming a bond. This enables the covering to be readily applied to the floor. The surface may be covered by a protective foil which prevents the covering from sticking to other objects and is removed before applying the covering to the floor.
