Concrete Cure and Seal

Curing of fresh concrete is important to develop the strength and durability within concrete. Curing involves the maintenance of desired moisture and temperature conditions within the concrete for a period of time.

Curing coatings are used to retain water in the concrete during its cure.

Sealers are often applied after the cure to help protect and beautify the concrete, improve dusting, prevent dirt penetration, and enhance freeze/thaw stability.

Concrete cure and seal coatings deliver both benefits of a curing agent and sealer in a single application.
