Rough concrete finishes are generally appropriate for surfaces subject to which condition?

• A. Aesthetics
• B. Water resistance
• C. Traction
• D. Acoustics

Answer: (C)

Texture that maximizes slip resistance is what rough concrete finishes provide. The rough surface creates more friction underfoot, giving better traction for pedestrians and anyone using the surface in wet or slick conditions. That makes rough finishes ideal for areas that must be walked on safely, like walkways, ramps, stairs, and pool decks. Water resistance, aesthetics, and acoustics aren’t primarily improved by roughness: water resistance relies on sealing and curing, aesthetics typically favors smoother or decorative finishes, and acoustics depend on sound-absorbing properties rather than surface roughness. So rough finishes are chosen mainly to boost traction.
