Most concrete surfaces have a naturally rough, textured
surface. The property of a floor that makes it slip resistant is its surface roughness.
This allows for a solid, safe interface between the walking surface and the
individual’s shoe, even when the surface is wet. On a microscopic level, all
surfaces have peaks and valleys. When paint is applied to the concrete surface,
the paint fills the valleys leveling off the properties that create a safe
walking surface. When a wet or otherwise lubricated contaminate is applied to
the painted surface, this can lead to a Maxi-Slip or as it is technically referred
to as “Boundary Lubrication”. In this consideration, only part of the shoe
bottom contact area touches the surface while the remainder skims over a
foreign contaminant, causing a slip and fall.
