These stresses can lead to a loss of adhesion between the support and the mortar. The strength of the substrates with respect to their ability to receive a coating \(mortar\) is characterized in particular by the value of minimum tear resistance of the surface to be coated. In this work, the use of a non\-destructive method which is both fast and easy to implement is employed to evaluate this support\-mortar adhesion."]
