Which finishing technique is recommended for joints between drywall sheets?

Using a joint compound and tape is the recommended finishing technique for joints between drywall sheets because this method creates a strong, smooth, and seamless connection between the sheets. The joint compound, often referred to as mud, is applied over the taped joint to fill in any gaps and create a flush surface that can be easily sanded down for a perfect finish. The use of tape reinforces the joint, helping to prevent cracking and ensuring durability over time.

In contrast, other techniques do not provide the same level of strength or finish. Applying a bead of silicone is generally not appropriate for drywall joints, as silicone is flexible and does not adhere well to drywall surfaces, which can lead to separation and cracking. Painting directly over the joint without finishing it can result in visible seams and an uneven appearance, as the texture of the joint will be apparent under the paint. Leaving joints uncovered compromises the structural integrity and can result in a messy and unprofessional look, as the raw edges of the drywall will be exposed and may become damaged over time. Thus, using joint compound and tape is essential for achieving a polished and durable drywall installation.
