Don't walk on them!!! We had lovely hardwood floors in Balto where I grew up. They were 95% covered with, both area rugs and scatter rugs. Twice a year my grandmother pulled up all the rugs and waxed them with floorwax, which might not have been sticky, but was slippery, at least at first.
To me, hardwood floors are a perpetual project.
I thought the new ones were covered with something that protected them, but apparently not.
