Is a specially formulated fibre cement sheet designed to provide a stable substrate for slate and ceramic floor tiles. It can be installed over new or existing timber floorboards, plywood or particle board flooring.

In dry areas, tiling may be applied directly to the Ceramic Tile Floor Underlay to form an impervious, easily cleaned surface.

For wet areas, and areas subject to accidental flooding or water splash, the installation of a waterproof membrane between the Ceramic Tile Floor Underlay and the tiling is required.
