The surfaces are cleaned of impurities that can be harmful for pretreatment and application. In addition, water-soluble salts are removed by suitable methods. The surfaces of the various materials are pre-treated as follows:

COLD-ROLLED SURFACES: The surfaces are treated with a suitable cleaning agent.

HOT ROLLED STEEL: Blast cleaned or sandblasted to degree of cleaning SA 2½ according to the standard ISO 8501-1:1988.

HOT-DIP GALVANIZED STEEL: Hot-dip galvanized steel structures that are exposed to the weather can be painted if the surface is sandblasted (SaS), so that the entire surface becomes matt.
