If you still decide to restore the old parquet-out of love for antiquity or if the parquet has some kind of artistic value, then it is necessary to completely recreate each rivet (plank) so that it is exactly the same color and size as the failed, which is out of order, Broken. When laying, new rivets should be higher than the floor level by 0.5-1 mm. Remove damaged rivets so that the neighboring ones are not damaged-split along the fibers into 2-3 parts, and then remove it from the nest. For good fastening, you will also have to take out a neighboring rivet, so that then you can easily insert them into place — rivets have crests, in the grooves of which you need to insert them.
