Around openings, what finishing steps should be performed to ensure edge quality?

• A. Edge the perimeter to establish a clean edge, bevel or chamfer sharp corners, then continue.
• B. Bevel opposite corners first.
• C. Finish interiors before edging.
• D. Ignore openings until the end.

Answer: (A)

Edge quality around openings comes from defining the boundary first and then shaping the edges. Start by edging the perimeter to establish a clean, crisp boundary around the opening. Next, bevel or chamfer the sharp corners so they won’t chip or flake as you continue finishing and to give a smooth transition for the rest of the surface. This sequence protects the edge while you work inward, helping keep the opening’s boundary neat and even. Finishing the interior first or delaying edging risks disturbing or rounding the edge, producing irregularities that are hard to fix later.
