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.

Instead, they often resort to a specially designed metal plate, in which the ends are bent at an angle of 90 degrees.
