Start by nailing the casing at the top of the door, then work your way down. 5. Make sure to countersink the nails so that they are flush with the surface of the casing. ### Step 4: Fill Nail Holes and Sand 1. Use wood filler to fill any nail holes or gaps in the casing. 2. Let the wood filler dry according to the manufacturer's instructions. 3. Once the wood filler is dry, sand the casing smooth. ### Step 5: Paint or Stain the Casing (Optional) 1.
