Hi, While tearing out the old carpeting (which ran up the walls about 6 inches) in our 70s-era sunken den, we discovered that the sheetrock ends about 6.5 inches above the floor and rests on a 1/2" thick piece of wood, which rests on a slab of concrete that is about 6 inches high. I would like to extend the wall down to the floor by adding a 6-inch strip of sheetrock along the bottom. To do this, I need to shave/sand back this newly exposed slab along one of the inside walls (one section of the slab juts out 1/2" past the sheetrock, while another section is about flush with the sheetrock. What tools can I use to do this? Thanks, Kim

While I was putting in a ceiling fan, the drywall puched from the attic side out a bit on the ceiling, Do I push it back up and spackle, or dig it out and patch? It is about a 2"x 2" area.
