21mm wide lead edging strip, sold by the linear metre. Supplied as a continuous length up to 5m. An excellent product for edging mosaic panels, thereby hiding cut tile edges, adhesive layers and substrate. This strip comes with a self-adhesive backing (simply peel off the yellow paper strip) and it will bond well with your mosaic if you have cleaned and dried it thoroughly, removing all debris and dust. Please note that the lead is extremely malleable and once pressed up against the edge of your mosaic its surface will undulate gently over the bumps beneath (unless your edges are very neat). Not recommended for outdoor use.
