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.

Steel: blast clean the steel to Sa 2½ grade, according to ISO 8501-1. The roughness profile should be adjusted, depending on the thickness of the product to be applied. Remove powder residues and abrasive residues from surface. These indications are generic, applicable to several products and merely informative.

Wood: sand it following the direction of the fibres with a medium grade sand paper.

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.
