Hardboard is a traditional board used for floor covering and the levelling out of old wooden floor boards. It gives a clean smooth surface which allows you to apply various floor coverings of your choice. One face is smooth while the other is coarse and textured which helps to secure the board to the substrate, however a ring shanked nail or staple will still be required. It is manufactured from very fine wood fibres, it is a cost effective board and can be used for a lot of different applications but is primarily used for floor covering.
