That's the thing for us, we've got floorboards beautifully done with what is probably Osmo, so I don't want a crappily finished staircase next to it.
What's the recommendation for prepping the stairs first (well aware I could read all this somewhere but I trust you guys more).
Palm sander and then some fine sandpaper? My sander can leave scratches sometimes, but that might be solved just by putting new pads on and making sure I do it properly.
At the moment the stairs are a bit dirty and have some paint on but they'll come up nice.
