Which statement defines Surfacing material?

• A. A material used to insulate pipes and tanks.
• B. A sprayed-on or troweled-on material applied to structural surfaces, such as acoustic or decorative ceilings, fire proofing, textured paints and plasters.
• C. A decorative finish applied to furniture.
• D. A material used exclusively as a moisture barrier on foundations.

Answer: (B)

Surfacing material are coatings applied to structural surfaces to finish, protect, or add function to a building element. They are typically installed by spray or trowel, rather than as panels or sheets. Examples include acoustical sprays on ceilings, decorative plasters or textured paints, and spray-applied fireproofing. This captures what these materials do and how they are applied in construction.

Insulation for pipes and tanks is about thermal protection, not a surface finish. A decorative finish on furniture isn’t applied to structural surfaces of a building. A moisture barrier on foundations is about sealing against water intrusion, not providing the finished surface or protective coating on structural members.
