There was some kind of vinyl sheet flooring on 1/4” plywood that I am removing to expose the subfloor, I am looking to add hard wood floors here. Is there any reason why the subfloor wood planks are diagonal? Do I need new plywood on this, then add the new wood floor, or can I just add new hardwood flooring directly to subfloor? Do I need add a felt underlayment? Google has a million methods, this is an old house so I want to do it right and thought you folks could offer some input.Also, I did try to scrape off the felt and adhesive but it was nearly impossible. Should I have just layed new floor on the old felt? There are other rooms with vinyl and felt that are currently waiting for demo. Thanks!!Edit- the felt was in the 1/4” plywood that was under the vinyl floor and it was probably vinyl adhesive so not legit felt.Tudor wood sub floors via /r/DIY http://bit.ly/2VymR6K
