The StucCoat Three-Coat Securock ExoAir 430 system typically consists of the following components, as determined by specific code and performance requirements.
StucCoat Three-Coat Securock ExoAir 430 is a complete stucco assembly for above-grade exterior walls, soffits and ceilings in residential and commercial buildings. It is a code-compliant assembly that is installed in three coats — for a system that is built to last.
Available StucCoat textures include Standard, Fine, Lace and Bold, and the system can be finished in any of Dryvit’s 250+ standard colors, which include high-performance StratoTone™ pigment technology for bold, lasting color.
This system also incorporates the factory pre-installed Securock ExoAir 430 air- and water-resistive barrier system for moisture management and can be enhanced with a reinforced crack isolation membrane for increased stress crack resistance. Fire-resistant assemblies are also available. (Consult with Dryvit / Tremco CPG Inc. technical services department for further details.)
The StucCoat Three-Coat Securock ExoAir 430 system’s concentrated and sanded cement plaster bases are installed as a three-coat scratch and brown system at a minimum 7/8-inch thickness complying with ASTM C926.
This system includes the factory pre-applied Securock ExoAir 430 air- and water-resistive barrier for maximum protection against air and water infiltration — and it also eliminates a time-consuming step from the installation and reduces quality control issues on jobsites.
Built within the StucCoat finishes, Dryvit’s high-performance StratoTone™ pigment technology means the system will have bold, vibrant, fade-resistant color for the long term.
The StucCoat Three-Coat system is naturally crack resistant thanks to its mesh and fiber-reinforced base coat, but an optional Crack Isolation Membrane can boost crack resistance even further with fiberglass mesh reinforcement.
Depending on the air- and water-resistive barrier, Dryvit textured finish coating, continuous insulation, and Tremco joinery and sealants selected, warranty terms can be configured from 10 up to potentially 20 years.
As part of Tremco Construction Products Group (CPG), Dryvit StucCoat systems have the added benefit of tested, proven compatibility with many Tremco sealants, air barriers and waterproofing products, and Willseal expansion joints — to help create truly comprehensive building enclosures.
