When applying baseboards, is it necessary to run a bead of some kind of (paintable) caulking along the top of it? I know this is done in spots where the wall bows and a larger gap exists, but what about if the baseboard sits pretty flush against the wall? The gap would be between hairline and dime in width.
I have unpainted wood running up the walls along my stairs, which was covered in carpet previously but is now exposed. I meant to paint it before I got new carpet recently, but I blew the timing on that and will be painting it now that the new carpet is in place.
