While installing hardwood floor on the ground floor, make a cellar between ground and floor to protect it from the ground dampness. The boards are laid along the joists on the bricklegs.

The boards of the floor should be 27 and 21mm long made of softwood and well dried. The boards must be joined on the joist. In order to achieve smooth floor, while installing the flooring, the rings on the adjoining boards should be turned to different sides. The floor is installed along the joists, laid and well adjusted, or floor beams. The boards of the floor must closely adjoin one to each other. That’s why their side edges are connected by grooves and then boards are joined. Hardwood floors mustn’t be installed too close to the wall because the wood absorbs moisture therefore expands with it, and floor may swell. A gap between boards and a wall (10-15mm) is covered by baseboard. The hardwood flooring must be started from the wall. The first board is nailed to the floor joists. The next 3-4 boards are laid without nailing. The boards are closely joined with the help of the wedges and iron cramps. After that the boards should be nailed. The whole work is repeated in the same sequence.
