(See photo below).
I have hardwood flooring that goes into stairs. The horizontal wooden slat right before the stairs is very slightly raised, by maybe an 1/8 of an inch, maybe even 1/16th. It's not a major problem, but I'm worried it's a tripping hazard which could end horribly wrong if you trip down the whole flight of stairs.
Is there a way I can make the two hardwood slats smooth with each other?
