Marmox Curved Multiboard 20MM (600x1250MM)
Looking for bathroom and wet room design inspiration? Consider the versatile Marmox Curved Boards! These flexible boards offer endless possibilities for creating archways, curved walls, curved bath panels, and more. Plus, they're designed for easy installation and cost-effectiveness.
Marmox Curved Boards are ideal for achieving curved designs with mosaic tiling. With their unique design featuring slits 2mm wide and 17mm deep removed from one side, these 20mm thick Multiboards can be easily bent to a radius as small as 200mm. Once secured against a frame or curved wall, they provide a low porosity concrete surface that's pre-primed and ready for tiling or plastering.
Whether you're a homeowner or a professional designer, Marmox Curved Boards can save you time and effort while offering a wider range of creative possibilities. Waterproof, insulating, and easy to install, they're an excellent choice for any bathroom or wet room project.
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 etc.
How to use
Against a curved solid surface, the boards are curved “inwards” to close the cuts, i.e. they are placed with the cut surface against the wall. The curved boards are then fixed to the wall with a continuous bed of flexible tile adhesive. Marmox Curved Boards can be used this way if the radius of the curve is 200mm or greater.
With centres at 300mm, the Curved Board can also be fixed to a frame using screws and washers.
Size
Marmox Curved Boards are made from 20mm Marmox Board, 600mm x 1250mm. The cuts on our curved boards are across the width.
