Without Mosaic Mesh sheets, mosaic tiles are floppy, unwieldy and prone to slippage. Mosaic Mesh is a simple, rigid plastic mesh with a self-adhesive backing. Simply stick it to the underside of your mosaic sheet and it gives complete support during tiling. Mosaic Mesh is supplied in a 300 x 300 mm size to suit most mosaic sheets. It adds practically and extra depth. It can easily be cut with a knife or scissors.
