What did you do wrong? Basic principles: The coating substrate must be checked for load-bearing capacity and freedom from release agents before each coating process. If this substrate is not sufficient, the unstable coating substrate must be removed, if possible stabilized, and primed in any case. If the substrate is possibly contaminated with release substances, these must be removed (surfactant wash etc., google), but if it is too smooth, roughen or apply an adhesion promoter (plaster and bonding primer). Basta!
