Which type of finish is commonly applied for a broom finish?

A broom finish is specifically designed to enhance traction and improve safety on concrete surfaces. This result is achieved by dragging a broom across the surface of freshly poured concrete, which creates a textured finish with fine grooves. This texture is beneficial for outdoor surfaces exposed to weather conditions, such as walkways, driveways, and patios, as it reduces the risk of slipping when wet.

While smooth finishes are aimed at providing an even, polished look, they can be slippery in wet conditions, making them less suitable for areas where footing is critical. Exposed aggregate finishes involve removing the top layer of cement paste to reveal the stones underneath, providing a decorative surface that doesn't offer the same functional benefits in terms of traction as a broom finish. Stamped finishes, on the other hand, use mats to create patterns and textures that mimic other materials, further diverging from the practicality offered by a broom finish.

Therefore, the correct answer highlights the unique purpose and application of the broom finish in achieving both functional and aesthetic benefits on concrete surfaces.
