Like it says, I didn't do as hot a job on spackling the area of my hallway and you can see where the perimeter of a big rectangular patch of sheetrock is now that I have painted the wall! I thought that I blended it enough, but the patch and the wall just weren't flush enough. Can I spackle over the paint? Will it stick to latex paint? I should probably rough it up with some paper first. Anyone done this.
