Statement: The correct application procedure for Hollow Heart CB is to drill a circular pattern around the internal decay pocket with evenly spaced holes.

• A. True
• B. False
• C. A Circular Pattern Around The Decay Pocket With Uneven Spacing
• D. Drill Randomly Around The Pocket

Answer: (B)

The pattern for applying Hollow Heart CB should follow the shape of the damaged area and the label’s instructions, not a neat, perfect circular ring around an internal decay pocket. Decay pockets are often irregular, and a circular pattern with even spacing can leave portions of the wood untreated or fail to reach all sides of the decay. The correct approach is to place holes around the perimeter of the affected area in a pattern that conforms to its contour and ensures the preservative can penetrate into the surrounding sound wood. That’s why the statement is not the recommended procedure.
