First time posting here. I'm working on an old house, discarded old baseboards and repainted a few walls. When about to put on new baseboards, I'm finding that my old baseboards were higher than the new ones, and so I'm having this ugly transition from were the edge was on the old base boards visible, see picture.
So, I will need to re-mud and repaint by the baseboard area. Any good tips on how to approach this? What mud is best to use on paint? All purpose? Hot Mud? Any other tips welcome on how to go about to fix this rookie mistake??
