A releasable bonding system especially suited for releasably bonding impermeable floor coverings (6) such as vinyl and linoleum in tile and sheet form to a floor surface (5). On preparing a suitable surface (5), a quantity of a first water-based adhesive (4) is applied, into which a porous intermediate membrane (7) can then be laid and brushed over carefully. Once a convenient area of the porous intermediate membrane (7) has been laid, a second adhesive (2) may be applied, into which the impermeable covering (6) can then be laid and rolled in the usual manner. The second adhesive (2) dries through the porous intermediate membrane (7) to the floor surface (5). At a time of replacement or repair, when the floor covering is removed (6), the porous intermediate membrane (7) is also removed, leaving an undamaged floor surface (5) with an adhesive residue which may either be washed away to remove it or have fresh adhesive applied over it.
