    The house was built in the early 1940s, and we removed the carpet, and it has oak hardwood flooring, but a professional who looked at it a long time ago said that it was too thin to be sanded, and that sanding it would destroy the grooves that hold it together, and cause it to come up. In some rooms it is finished, but the finish is in bad shape, and in other rooms it is unfinished. Is it possible to DIY finish it or oil it?

    Wideview picture and detailed picture recommended. If a pro hardwood refinisher has that advice it is probably sound. Did he recommend screen and recoat to dress it up?

    I'm not sure if he reccomended that, it was a long time ago. I think he just said that to sand it flat, they would have to sand past the groove that holds it together.
    Here is a picture:

    It’s cupping pretty bad. Usually related to humidity/ moisture levels.

    If it was built in the '40s I would guess it is 3/4" and should be sandable.
    My recommendation is to get a second opinion.

    Stick a business card or something similar in between two boards if you can and mark it with a pencil. You should land on the tongue and get a feel for how much wood you have above the t&g.

    By the way Mike, I didn't see cupping in the picture. Not saying it isn't, just that I can't see it. Crowning? Maybe.

    Sides look higher than center to me, U shaped from standing above. Moisture higher underneath than on top. Timeframe? Happened long time ago and stayed that way or current moisture issues for the duration.
