A liner (1) for lining an aperture in sheet material such as plasterboard, the liner having (a) an annular ring (2) defining a hole (4) having a smaller diameter than an aperture to be lined; a slot (3) extending from the inner periphery (5) of the hole to the outer periphery (6) of the ring (2), so sized and shaped as to allow the liner (1) to be passed from one side of the aperture to the other. A lip (8) is optionally provided around the hole. Resiliently-deformable liners are also provided. Also provided are methods of repairing, reinforcing or re-sizing apertures in sheet materials. |
