Grinding is the most widely used method of removing laitance layers and other impurities. Standard PSK 2703 differentiates between two classes of grinding: surface and in-depth grinding. The process of surface grinding removes all fine laitance and other traces of weak surface layers from the entire floor area, revealing the fine-grained aggregate.
