This DIY tutorial aims to teach you an easy to learn way, about how to lay fibreboard underlay for laminate and wood floors.


Before anything else, it is important to mention that preparation of your sub-floor is the key to success when laying an underlay. It has to be as flat and even as possible, though we understand that there will be some imperfections. As long as these imperfections are minimal, fibreboard underlay can be used to correct this unevenness and this is one of the main reason it has become so popular.

Apart from that, fibreboard underlay provides great sound reduction and thermal insulation and all these in an affordable price.

Bear in mind, that you should leave a 2mm expansion gap between the staggered boards and 10mm gap around the perimeter of the room.
