Red Seal Drywall Finisher and Plasterer Practice Exam

What is feathering in drywall finishing?

1. Applying primer to the drywall

2. Blending the joint compound edges into the drywall surface

3. Sealing the joints with tape

4. Using a smoother to flatten the drywall

The correct answer is: Blending the joint compound edges into the drywall surface

Feathering in drywall finishing refers to the technique of blending the edges of the joint compound into the surrounding drywall surface. This process is crucial for achieving a smooth, seamless transition where the joint compound meets the drywall, effectively masking joints and imperfections in the surface. When feathering is done properly, it allows for a gradual thickness of the joint compound, which minimizes the visibility of seams after the finishing process. This technique often requires the use of multiple layers of compound, with each layer being applied a little wider than the previous one, allowing for smoother edges that fade into the drywall. While applying primer, sealing joints with tape, and using a smoother are all important processes in drywall finishing, they do not specifically address the blending of joint compound edges, which is the essence of feathering. Thus, understanding feathering is essential for any drywall finisher looking to produce high-quality work.
