COEFFICIENT OF FRICTION ACCEPTED INDUSTRY STANDARDS

Ceramic, Terrazzo, Marble, and most mineral surfaces treated with Nano-Grip
are actually safer in wet conditions than in a dry untreated surface. All surfaces shall
be tested independently for actual results.


“A static anti-slip coefficient of friction of .50 or above is considered a safe walkway surface with a dry condition. A reading below .50 is considered an unsafe walkway surface.”
As adopted by Underwriters Laboratory (UL) and
the American Society of Testing and Materials (A.S.T.M)

.60 or above - Very Safe
.50 to .59 - Relative Safe
.40 to .49 - Dangerous
.35 to .39 - Very Dangerous
.00 to .34 - Unusually Dangerous
