• A. True
• B. False
• C. Not stated
• D. Depends on slab size

Answer: (B)

Edging is about shaping the edge with controlled, steady pressure to create a durable, rounded profile, not crushing it with brute force. You don’t push with maximum pressure, especially at the corners, because that can gouge away paste, deepen micro-cracks, and concentrate stress where the edge is most vulnerable. Instead, you use a moderate, consistent pressure and make gradual passes along the edge to form a smooth, rounded edge without risking chips or spalling. Start from a steady pace along the edge and work toward the corners with careful, controlled passes, checking that the edge remains even rather than forcing the tool into the corner.
