Here is my first time doing burnt plywood flooring. it was actually easier than I expected, you get yourself a torch and a propane tank 'yes you burn it outside lol' lightly toast your wood Don't Go full char. check out a couple videos on YouTube, you'll be a professional wood burner in no time. I've done plywood flooring before and it holds up really well. Just do your research you'll be fine. I put a small video of me burning the plywood check it out if you'd like.
