How old are we talking? Victorian (like mine) or mid-century?

You could check on thickness by pulling up a threshold thing between rooms. If there's a bit of thickness to it, you could probably very gently sand it with fine grit (will take lots longer) and reseal, but if it's super thin veneer, I'm not sure what your options are other than buffing it and seeing about putting some sort of protective seal on top of what's already there.

Yah it's too hard to tell just by some words on a page. Some photos of what you are talking about and a date or rough estimate as to when it was installed. And a location (general idea like a city) would be enough. Certain things went on at certain times in certain cities with certain products. What was popular in NYC in the 1960's may not have made it to "anywhere" Wisconsin.

Very thin finger parquet was popular in apartments in NYC in the 1960's, for example. Thicker products were used and are still in use in the Palace of Versailles outside of Paris. Some of those old products were more than 2" thick.

Photos and a bit more background and we will be happy to help.
