Elastomeric Finishes
Stuc-O-Flex® Elastomeric Acrylic Finish
Flexible, Breathable Stucco Systems Engineered for Long-Term Performance. Stuc-O-Flex® is a high-performance elastomeric acrylic stucco finish engineered to improve exterior wall performance. It accommodates building movement, manages moisture, and maintains long-term surface durability and appearance across a wide range of climates and applications.
Performance
Why Stuc-O-Flex®
Many exterior wall failures stem from rigid cement-based finishes that cannot accommodate movement or effectively manage moisture over time. As buildings expand, contract, and respond to environmental stress, traditional stucco systems are prone to cracking, water intrusion, and surface degradation. Stuc-O-Flex elastomeric acrylic technology is engineered to address these challenges directly. Its flexible, breathable formulation works with the wall assembly rather than against it, reducing risk during installation, inspection, and long-term service life.
Accommodate Building Movement
Elastomeric formulation flexes with expansion, contraction, and environmental stress.
Manage Moisture Effectively
Reduces water intrusion risk while allowing controlled moisture vapor transmission.
Breathable Formulation
Works with the wall assembly rather than against it, promoting drying and reducing trapped moisture.
Long-term Durability
Sustained color and surface appearance across demanding climate conditions.
