Concrete: the concrete should be allowed to have a minimum 28 days to harden, a minimal tensile strength of 1.5 N/mm² and a minimum compression resistance of 25 N/mm². The surface must be clean, dry, free from laitance, old paints and other contaminants.

Self-Protection Asphalt Screens with Mineral and Asphalt: the surface must be well adherent, clean, dry and free from oils, grease, dust and other contamination. Wash the surface with neutral detergents, followed by washing with clean high pressure water.
