The present invention relates generally to an improved drywall finishing system. The system is comprised of a container, a powdered compound and an applicator, and several methods of applying the compound to a drywall surface via the applicator. The first method of the system involves applying the compound to a drywall surface via the applicator to detect rough, un-sanded, or improperly sanded areas that can then be re-sanded as needed. Further, the second method of the system involves applying the compound to a drywall surface wherein the powder adheres to any high spots, low spots, or imperfections in the surface, wherein said spots can be re-sanded as needed.
