Question 1

What is the first coat of joint compound applied during drywall finishing called?

Accepted Answer

Tape coat (embedding coat)

The tape coat, also called the embedding coat, is the first application and is used to embed paper tape into the wet compound over joints.

Question 2

How many total coats of joint compound are typically required to achieve a professional-quality finish?

Accepted Answer

3 coats

Answer

Three coats are the professional standard: the tape coat, a filler coat, and a finish coat, each applied only after the previous coat has fully dried.

Question 3

What type of drywall tape is most appropriate for finishing inside corners?

Accepted Answer

Paper tape

Answer

Paper tape is preferred for inside corners because it can be creased along its center crease and feathered smoothly into both adjoining surfaces.

Question 4

What is the primary purpose of metal or vinyl corner bead on outside drywall corners?

Accepted Answer

To protect the corner from impact damage and provide a straight finishing edge

Answer

Corner bead protects vulnerable outside corners from dents and chips while giving finishers a consistent straight edge to feather compound against.

Question 5

In drywall finishing, what does the technique called 'feathering' mean?

Accepted Answer

Thinning the compound edges so they blend imperceptibly into the surrounding wall

Answer

Feathering means gradually tapering the edges of each compound coat outward so the transition from joint to wall surface becomes invisible.
