Q: I sanded down old oak hardwood floors. Applied varathane, waterbased stain. It was way too dark, so I decided to resand the floor. But I cannot remove all the previous stain. What can I do to get it all off?
A: Most of the stain should come off fairly easily. It probably would be impossible to remove all stain from the heavy grain, but that would be irrelevant when staining again. I’m only talking trace amounts. 50 Grit should be more than course enough to remove the stain. I might even try 60 grit.by
