COEFFICIENT OF FRICTION ACCEPTED INDUSTRY STANDARDS
Ceramic, Terrazzo, Marble, and most mineral surfaces treated with IntellaTread
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 |
