Which statement about Cornerite is true?

Which statement about Cornerite is true?

• A. It has outstanding legs of at least 2 inches
• B. It has no leg length requirement
• C. It is only used on exterior corners
• D. It is not used in plastering

Answer: (A)

Cornerite is a corner reinforcement used in plastering to form and strengthen corners, with legs that extend onto each wall surface. Those legs must be at least 2 inches long to provide enough embedment and a solid key for the plaster on both sides of the corner, helping prevent cracking and movement. This requirement for a minimum leg length is what makes the statement about having outstanding legs of at least 2 inches true. The other ideas don’t fit: there is a leg length requirement; Cornerite isn’t limited to exterior corners—it's used on interior and exterior corners—and it is indeed used in plastering to create durable, reinforced corners.
