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.
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.
