When selecting floor finishes for a high-traffic area, which property directly relates to slip resistance?

• A. DCOF rating; prioritize finishes with acceptable DCOF values; durability and cleanability also matter.
• B. Color matching is the only requirement.
• C. VOC content alone determines slip resistance.
• D. Slip resistance is not a concern.

Answer: (D)

Slip resistance is determined by how much traction a floor finish provides, which is measured by the dynamic coefficient of friction, or DCOF. In high-traffic areas, you want a finish with an adequate DCOF so feet don’t slip when the floor is wet or contaminated. The higher the DCOF, the better the grip and the lower the slip risk, and standards specify minimum DCOF values to meet safety needs. DCOF is a direct indicator of friction performance, whereas other properties like color matching or VOC content don’t measure slipperiness. Durability and cleanability matter for long-term performance, but they don’t quantify traction. So the property that directly relates to slip resistance is the DCOF rating.
