    StoPowerwall® ci

    StoPowerwall® ci is a portland cement stucco wall covering that is intended for use over code compliant concrete, concrete masonry, and frame wall construction. It incorporates a fluid applied air and water-resistive barrier, code compliant paper or felt water-resistive barrier (WRB), drainage cavity, code compliant metal plaster base, portland cement stucco, Sto primers, and Sto textured or custom cast finishes.

    StoPowerwall stucco is ASTM C926 compliant and is installed in two coats in conformance with ASTM C926 practices. StoPowerwall stucco is available as a concentrate to which graded sand is added at the job site, or pre-sanded to simplify mixing in the field. Sto proprietary integrally colored textured finishes or Sto custom cast finishes are used in lieu of portland cement stucco finish to achieve brighter, richer colors and textures, and offer a wide variety of finish looks such as stone, brick, or wood on a single substrate.
