Preparation of surfaces
Oxidised steel without calamine:
Mechanical cleaning at the grade St2, of Svensk Standard SIS 1967
New concrete:
Chemical washing in order to remove laitance layers and efflorescence
Worn concrete:
Grinding, milling, shot peening, depending on the cement conditions.
Grinding is suitable for removing surface dirt on consolidated cements.
Shot peening and milling are more suitable for old and crumbling cements or in case of removal of old paints.
These operations must always be followed by an appropriate dust removal.
