What is the first step involved in taping drywall joints?

1. Apply joint compound

2. Place tape over compound

3. Cover with more joint compound

4. Sand the area smooth

The correct answer is: Apply joint compound

The first step in taping drywall joints involves applying joint compound. This is a critical foundational step because the joint compound creates a bed for the tape to adhere to, ensuring a strong bond. The purpose of applying joint compound initially is to fill in the gaps and provide a smooth surface where the tape will be placed. Properly applying the joint compound at this stage prevents air pockets and ensures that the tape can bond effectively, which is vital for achieving a seamless finish. Once the joint compound is applied, the tape can be positioned over it, followed by additional layers of joint compound for smoothing and finishing. Skipping or improperly executing this initial application would compromise the integrity of the taping process.
