A sealed floor covering is made of PVC sheets which are butt-jointed along parallel edges. A temporary bonding tape is applied on top along the butt joint, on the underside a groove is produced along the joint and of depth less than the sheet thickness, this groove is filled with a PVC welding material which is then welded to the adjacent sheet. The weld is cooled, its projections beyond the smooth underside are smoothed off, and finally the bonding tape is removed. Reliable and simple method of making permanent flooring, minimal mis-cutting and wastage. |
