Which molding is used to finish an interior surface at a right angle to the wall?

• A. shoe molding
• B. concave molding
• C. quarter round
• D. marker piece

Answer: (A)

Finishing a base area where the wall meets the floor requires a trim that fills the tiny gap and creates a clean line at a right-angle joint. Shoe molding is designed for that exact job: it sits against the baseboard and the floor, bridging the seam so the transition looks neat and consistent, even when the floor surface isn’t perfectly flat or the gap isn’t uniform. The small, unobtrusive profile makes it ideal for this interior finish. In contrast, concave molding is used for decorative coves and rounded transitions, quarter round provides a larger curved edge for a rounded transition rather than a straight right-angle finish, and a marker piece isn’t a standard trim used for this purpose.
