Concrete surface deterioration is usually referred to as scaling. Scaling is a local flaking or peeling of the finished, hardened concrete surface, resulting primarily from multiple freeze-thaw cycles. The condition can be aggravated by the presence of de-icing materials such as salt. Any product that is intended to melt ice and snow can contribute to concrete scaling. Even products labeled Safe for Concrete can contribute to scaling. The probability that scaling may occur can be reduced or eliminated by using a durable concrete mix and following recommended concrete placing, finishing and curing/sealing practices performed by an experienced concrete contractor.
