The DRYLOK® Sealed Cladding System is a face barrier coat system for portland cement-based plaster. It is the only code-approved, tested, and warranted system for exterior cladding in all climates — including warm, humid zones. It is well-suited for areas that are susceptible to tropical storms, hurricanes, other weather extremes, and a high airborne salt concentration.

Why Use the Sealed Cladding System?
When stucco cladding systems are deployed in harsh, damp environments, they require a “face barrier coat system” that includes proper sealants of all penetrations. This prevents water from passing through the cladding system or around the penetrations. With this system in place, it eliminates the need for a “drain plane” system since there is no water to “manage” behind the stucco
Designed for all climate zones, as defined by the International Energy Conservation Code, this system is well suited for use in Zone 1, 2, and 3.
