In a floor deck, the finished surface installed over the subfloor to provide the walking surface is called what?

• A. Upper
• B. Finished
• C. Sand and gravel
• D. Carpeted

Answer: (B)

The key idea is that the final surface you walk on is the floor finish, or finished floor. After the subfloor is in place, the next layer is the finishing material that creates the actual walking surface, whether that’s wood, tile, vinyl, or carpet. That’s why the term “finished” best describes this layer. The other terms don’t fit as the general concept: “upper” isn’t a flooring term, “sand and gravel” is a base material rather than the finished surface, and “carpeted” describes a type of finished surface rather than the generic finishing layer itself.
