we were thinking about restoring the parquet floor in our living room ... the floor is dark red in color, is varnished and i belieev it is not stained .. there are a few scratches (furniture marks) on the floor and very fine gaps .. i was wondering if could use a wood filler and then reseal it with a floor varnish and avoid sanding the floor altogether ... because the floor is in good condition otherwise has a good amount of shine left ..
