Once drywall is hung, the joints will need to be hidden behind tape so the wall appears seamless. Drywall taping and finishing are easy projects if they are done correctly. In order to avoid nail pops, lumpy mud, dips, ridges, and tape bubbles, follow the steps below.
You will need:
- Drywall sander
- Dust mask
- 4-in-1 screwdriver
- Mud pan
- Sanding pole
- Sanding block
- Dry sanding sponge
- 120-grit sandpaper
- Taping knife
- Utility knife
- Drywall knife
- Hammer
- Stain-blocking primer
- Drywall compound
- Setting compound
Step 1: Slide the drywall knife across the fasteners that anchor the drywall. A clicking sound will reveal any nails or screws that protrude above the drywall surface. Drive these in using the Phillips head of the screwdriver. Tap in any nails using the hammer, driving the nail head slightly below the surface of the drywall. Use a utility knife to remove torn or loose paper. Prime these areas with a stain-blocking primer.
Step 2: Nail in the metal corner bead to the drywall. Make sure to leave a gap of 1/8 inch along the flange. This will serve as a pocket for the drywall compound. Apply the setting compound, using a single length for each corner. This will prevent any creases or bumps from developing where two pieces are joined. Fill in any deeps gaps and areas around electrical boxes. Use the taping knife to remove any bulges of compound.
Step 3: Apply a coat of drywall compound and tape, covering the joints. When dealing with large gaps, fill them in with setting compound, then tape over them. Apply two more coats of compound in order to smooth the joints. Scrape the drywall knife against the drywall to remove any excess compound.
Step 4: Once all compound has dried, sand it, focusing on the edges where the compound blends into the drywall. Sand any corners using a dry sanding sponge. If the sanding ends up scuffing the paper tape, recoat these spots.
