How to Use Joint Compound
- 1). Finish a drywall joint by applying joint compound directly to the joint with a joint knife. The layer should be about 1/8 inch thick.
- 2
Smooth a strip of joint tape over the area. (Tape with adhesive doesn't require the first layer of joint compound.) Press the tape down firmly with a joint knife, squeezing out air bubbles and excess compound. - 3). Let it dry. This could take up to 24 hours.
- 4). Sand any areas that poke up and cut off any tape that sticks out or has obvious bubbles under it.
- 5
Apply a thin coat of joint compound about 6 inches wide over the taped area. - 6). Let that layer dry.
- 7
Sand the compound down so it's smooth and flat.
