Flat base with backing metal plaster base is Type:

Flat base with backing metal plaster base is Type:

• A. FB
• B. FR
• C. FF
• D. FU

Answer: (A)

Understanding plaster base types helps you match the substrate and reinforcement to the plaster finish. A flat base with backing metal plaster base uses a flat base surface paired with a metal backing to provide rigidity and a strong key for the plaster. This combination is captured by the FB designation, making it the correct choice for “Flat base with backing metal plaster base.” The flat base ensures an even, uniform plane for the plaster, while the metal backing resists movement, helps prevent cracking, and gives the plaster something solid to adhere to. The other codes describe different base configurations and don’t match the described setup, so they aren’t correct for this description.
