That looks like real progress! I’ve painted the floor white. You need at least 3 coats to get good coverage (I did 4). I’m not 100% happy with the result, but the imperfections are purely aesthetic. I’ll leave it like this for now and do the beauty corrections at the end, when everything else is finished and I still have time left.
I actually wanted to paint the floorboards white too, but it looks much better like this!
