A method of laying floor or like surfaces with desired material, wherein the floors or like surfaces are supported by or comprised of rigid units in the form of boards (2) or like elements. The boards are provided with tongues and grooves on respective edges thereof to enable boards to be joined to mutually adjacent boards. The method is mainly characterized by using boards (2) that have been provided with a friction layer (6) on their undersides. A corresponding friction layer (7) is placed on the underlying sub-floor (1). The boards may be laid loosely on the friction layer of the sub-floor and mutually joined to adjacent boards solely by coaction between the tongues and grooves of respective boards in the absence of any binder. The invention also relates to floor-laying material for use when applying the method |
