The method comprises making a riser surfacing panel 14 of heat fusible plastics material sheet 15, adhesively bonding the panel to the riser so that its upper edge aligns with the step surface, applying step surfacing 11 comprising plastics material sheet to the step surface, the step surfacing meeting the riser surfacing panel at the step edge, then fusing the plastics material of the step surfacing to the plastics material of the riser panel. The plastics material of the riser surfacing panel and the step surfacing may be the same. The riser surfacing panel may be directly adhesively attached to the riser or may be assembled onto a backing plate 16 which is then adhesively attached to the riser. The backing plate may be aluminium. |
