I am in the process of a kitchen makeover. My kitchen had the wallboard type material as a backsplash. We removed that but in doing so, the outer layer of the drywall was also removed. Will putting a "skim" coat of joint compound followed up with a good primer be sufficient to install new DPI (that's the brand name) wall covering? This is used simply as a inexpensive backsplash between countertop and bottom of cabinet as well as a partial wall behind the stove. Your advice and suggestions are greatly appreciated.
