When choosing this method of laying the parquet, first of all, it is necessary to check how even the surface is, and with insufficient evenness, you will need to make a screed, and then install the lags. Parquet is recommended only in rooms where humidity does not go beyond the value of sixteen percent. Laying on the lags is permissible only a parquet board, with a thickness of at least twenty -five millimeters. As for the direction, the parquet board should lie perpendicular. The first board is placed on a stretched cord, and the joints between the parquet should be dense. However, a gap of half a millimeter is allowed. Constantly control of the strength of the stacked parquet, in order to avoid corrections.

During the laying of the last row of the board, it does not rarely happen that the width of the board is slightly larger than necessary. In this case, the board must be cut in the longitudinal direction, for which the cut line should be carefully outlined. When the last row is laid, bars and brackets can not be used. Instead, they often resort to a specially designed metal plate, in which the ends are bent at an angle of 90 degrees.
