There’s a real number behind the term. Slip resistance is measured by something called the Coefficient of Friction, or COF — a rating that tells you how much grip a surface provides underfoot. OSHA recommends a minimum COF of 0.5 for walking surfaces. The ADA sets the bar higher, at 0.6 on flat surfaces and 0.8 on ramps, for any space that serves the public. Your retail store qualifies.
Most floors that look fine when dry fall well below those thresholds the moment they get wet. That’s the problem. A customer walking in from a rainy parking lot in Bohemia, or tracking in slush from a Suffolk County winter, is walking on a very different surface than the one you tested on a dry Tuesday afternoon.
We don’t guess at slip resistance. We select the right anti-slip aggregate — aluminum oxide, quartz, or silica sand — and broadcast it at the correct density into the topcoat to hit a target COF that meets or exceeds what your space legally requires. That’s the difference between a floor that’s “probably fine” and one that’s actually compliant.
