Marmox Curved Boards are 20mm thick Multiboards which have 2mm cuts spanning the width of the board. This allows Marmox curve boards to be folded in on themselves to a create a radius as small as 200mm. When secured against a frame or a curved wall, they present a low porosity concrete curved surface which is pre-primed ready for either  mosaic tiling, render or plaster. They be used to clad, waterproof and insulate archways and curved walls and also to create curved partition walls, curved bathroom panels, moulded tiled seats, round or curled cubicles.
