Meet U-STUCCO™, industry’s lightest ‘true’ one-coat stucco that is revolutionizing the stucco industry with its thermal, fire, water and acoustic insulation properties. It’s an ultra light-weight (1/7th weight of the conventional stucco) hydrophobic, high crack and corrosion resistant, UV reflective, ready-to-use powder-mix product. It provides fire resistance (2hr rated @1200°C/ 2192°F) as well as thermal (up to R 2.2 per inch), water and acoustic insulation (38 dB).
U-STUCCO’s simple one-coat application process greatly reduces time and labor expenses and renders traditional 3-coat application obsolete. U-STUCCO™ can be applied in a single pass of up to 1 inch to nearly any substrate, including plywood, OSB, gypsum, masonry, AAC, steel, foam and plastic substrates.
U-STUCCO™ is ideal for achieving superior energy efficiency. It can be used in conjunction with EPS, XPS, ICF or Fiberglass (Mineral Wool) to create wall assemblies with higher insulation R values and improved crack and water-resistance complying with California Title 24 code helping you build sustainable and energy efficient living spaces. U-STUCCO™ may also be used over wood or gypsum backing and as a scratch and brown coat application for traditional stucco systems.
U-STUCCO™ is 99% inorganic and contains 40% post-consumer recycled content making it a true green product. It is a Class 1 (A1) non-flammable material therefore it doesn’t burst into flame or emit any toxic gas when exposed to fire. It allows your building to breathe and prevents mold and mildew.
U-STUCCO™ can be used both in new construction and renovation projects. It can be applied on various substrates such as OSB, plywood, concrete, cinder blocks, bricks, densglass, drywall, sheetrock, EPS, XPS, ICF, AAC, wood and steel structures.
Apply by hand trowel or plaster gun.
The minimum thickness over any substrate is inch (5 mm). Some assemblies may require specific minimum thickness. U-STUCCO™ can be applied up to 1 inch (25 mm) thickness with a single pass.
U-STUCCO™ is a high-quality blend of white portland cement and mineral based lightweight aggregates that conforms to ASTM C926 which is developed as a replacement to job-site mixed scratch & brown base coat stucco. U-STUCCO™ meets code criteria for exterior portland cement plaster.
