Preparation of surfacesi
New concrete:
Chemical washing in order to remove laitance layers and efflorescence
Worn concrete:
Grinding, milling, shot peening, depending on the concrete conditions.
Grinding is suitable for removing surface dirt on consolidated concretes.
Shot peening and milling are more suitable for old and crumbling concretes or in case of removal of old paints.
These operations must always be followed by an appropriate dust removal.
