So my kitchen had a terrible sheetrock job.... actually pretty much the whole house. Unfortunately ripping out the cabinets and rerocking the whole thing isn't plausible considering we're living here right now. I'm fairly confident that I have the skill it takes to fix the ugly looking seams, but i'm not sure if joint compound will stick to a painted surface? While i'm at it, i decided i'd just texture the whole room as well. i'm fairly certain it won't stick well to dirty surfaces, so cleaning will be an obvious first step.
