Meet The Next Generation of Fire-Resilient Construction

U-STUCCO™ — The Future of Stucco

U-STUCCO™ is redefining the stucco industry as the world’s first truly ‘insulated’ stucco, combining advanced thermal, water, and fire-proofing properties in a single solution. Ultra-lightweight, hydrophobic, crack- and corrosion-resistant, and UV-reflective, this ready-to-use powder mix is engineered for unmatched durability and long-term performance.

Energy Efficiency

U-STUCCO™ achieves an R-value of 2.2 per inch, fully compliant with California Title 24 energy codes. By covering thermal breaks in wall assemblies, it significantly boosts insulation performance—making it the ideal solution for raising R-values across conventional and high-performance wall systems.

Fire Resistance

As the ultimate fire-protective coating, U-STUCCO™ withstands extreme temperatures exceeding 3,000°F without igniting, smoking, or spreading flames. Compatible with steel, ICF, CMU, AAC, concrete, wood, and metal frame structures, it delivers unparalleled safety and peace of mind.

Composition & Standards

Made with high-performance white Portland cement, mineral-based lightweight aggregates, and post-consumer recycled content, U-STUCCO™ conforms to ASTM C926 standards for exterior cement plaster while meeting stringent EPA and OSHA environmental regulations.

Application & Labor Savings

U-STUCCO™ eliminates the need for traditional three-coat stucco systems with its one-coat process—saving both time and labor. Applied in a single pass of up to 1 inch, it bonds seamlessly to nearly any substrate, including EPS, XPS, ICF, CMU and AAC blocks, 3D-printed concrete, Mineral Wool, ZIP System panels, DensGlass, fiber cement board, MgO panels, and steel.

Moisture Protection

Water-resistant, hydrophobic, mold- and mildew-resistant, and completely V.O.C.-free, U-STUCCO™ is perfectly suited for both interior and exterior WRB applications.

Sustainability & Versatility

Designed as an eco-friendly replacement for job-site mixed stucco (scratch, brown, and finish coats), U-STUCCO™ also functions as interior plaster, producing a smooth sanded finish.

Ease of Use

With minimal training required, U-STUCCO™ can be applied quickly by trowel or spray, making it accessible for crews of all sizes and skill levels.

U-STUCCO fireproof stucco proven to withstand intense wildfires, providing industry-leading fire-resistant building solutions.
