Surface joints must be placed within the tiled surface regardless of substrate conditions. They provide stress relief from movements in the tile field due to thermal and moisture expansion/contraction and loading. Schluter-DILEX-EZ 6 + 9 are prefabricated, maintenance-free surface movement joint profiles suitable for residential to medium-duty commercial aplications. The profiles feature rigid PVC side walls, which are connected on top and bottom by soft PVC movement zones that form the visible surfaces. These profiles separate individual fields in the tile covering and accommodate movement through the soft PVC movement zones. Dilex-EZ 6+9 is sold per 8' piece
