Why is an exposed aggregate finish often chosen for outdoor surfaces?

• A. It is easier to clean
• B. It blends well with natural landscapes
• C. It provides better traction
• D. It is less expensive to install

Answer: (C)

An exposed aggregate finish is often chosen for outdoor surfaces primarily because it provides better traction. This textured surface is created by removing the top layer of cement paste to reveal the underlying aggregates, such as stones or pebbles. The coarse texture enhances grip, making it especially beneficial for areas that may become wet or slippery, like driveways, walkways, and pool surrounds. This increased traction improves safety for pedestrians and is an important consideration in the design of outdoor spaces.

While other options may hold some merit in specific contexts, they do not describe the primary reason for selecting an exposed aggregate finish as effectively as the traction aspect does.
