Applying and Finishing the Joint Compound
The application of joint compound is a critical phase in large patch repairs. Follow these steps for a flawless finish:

- Reinforce with Tape: Use paper or mesh tape over the seams to reinforce the joints. This prevents cracks and enhances durability.
- Smoothing and Sanding: Once dry, sand the surface to a smooth finish. A well-sanded surface ensures that subsequent layers adhere properly.
- Final Coats: Apply additional coats of joint compound, sanding lightly between each until the surface is even and flawless.
