Step 3: Feather and sand the next layers
When the compound is dry, sand it with a 120-grit sandpaper attached to a wide sanding block. Wipe away the dust and apply a second coat of compound using an 8-inch compound knife. Feather the compound out even further on the second coat. Once the second coat is dry, sand again using the 120-grit sandpaper. Wipe down the wall and apply a third coat of compound, again feathering out beyond the edge to make a completely smooth finish. Once it is dry, sand the surface with a 200-grit sandpaper so that it is ready for priming and finishing.
 Feather out the next two coats of joint compound with an 8-inch joint compound knife.
