Laitance removal
Laitance Removal
Laitance is a weak, powdery layer that forms on concrete surfaces as they cure. It must be removed to ensure strong adhesion of screeds and coatings.
Common methods for laitance removal:
Mechanical Grinding: Uses diamond grinders to strip the weak surface layer.
Shot Blasting: Propels steel beads to roughen and clean the surface.
Scarifying: Uses rotating cutting tools for aggressive removal.
Chemical Etching: Involves acid-based solutions to dissolve laitance.
