Construction Performance Guidelines
INTERIOR CONCRETE SURFACES ARE POWDERY
Concrete surfaces shall be sufficiently hard to prevent powdering which results in exposure of the aggregate.
One-Year - Work and Materials · Surface deterioration due to owner-applied substances is excluded from the statutory warranty.
Where powdering occurs exposing the aggregate the concrete surface shall be repaired to provide a hardened surface.
Some dusting of the concrete surface may normally occur; however, where the aggregate becomes exposed the condition is considered excessive. The colour and texture of a repaired area may not match the surrounding concrete.
