A coating layer with the layer thickness “a” remains on the wall only then, if the limiting value of the shear stress between the states of rest and flow is not exceeded. This τ-value is the yield point τ0 [Pa]. As the calculation shows, the yield point is independent of the layer width and length. Thus, the wet layer thickness of a coating which remains on a vertical wall can be calculated as:

Equation 3.5

a = τ0 /(ρ ⋅ g)
