Hi,

We recently ripped up old carpet in our entry stairway and re-stained the underlying hardwood. Removing the carpet left an ugly outline of the thick white latex paint that stick out a few millimeters and traces all the way down the staircase (see photos).

I tried to scrape and sand down the paint outline so we could then repaint it, but much of the paint started chipping. So, I'm now trying to sand down the top layer of paint, spackle over it, sand it down, and repaint. I have no idea if this is actually going to work well, so I thought I'd see if anyone here has any other suggestions.
