Laitance, Dusting, and Weak Surface Layer (Concrete / Substrates)
Laitance, Dusting, and Weak Surface Layer (Concrete / Substrates)
Floor Detective® Claims and Conditions Guide
Summary
Laitance, dusting, and weak surface layer conditions refer to the presence of a fragile, low-strength surface film or powdery layer on concrete substrates. These conditions may result from finishing practices, water-cement ratio imbalance, curing variability, or surface overworking during placement. While the slab may remain structurally sound, a weak surface layer may interfere with adhesive bonding or flooring system attachment. The condition reflects surface integrity and preparation variables rather than
