THE CITY OF SUNNY ISLES BEACH <br />PROJECT NO. 21-1011 <br />BUILDING DEPARTMENT RELOCATION TO ANNEX <br /> <br />Project No. 21-1011 November 2024 092423-23 <br /> <br />brown coat, and stucco finish, must be applied. <br />c. Where the surface is too smooth, dense, or non-absorbent to receive the air <br />barrier or stucco components. <br />4. Verify adequacy of lath attachment with respect to design wind pressures. <br />5. Do not install stucco over unprepared substrates or any substrate where adhesion is <br />in question. <br />6. Where metal lath is used, Sto Flexyl or Sto Watertight Coat may be installed over the <br />stucco brown coat as an air/moisture barrier with proper integration of other air <br />barrier materials. <br />3.3 INSTALLATION, GENERAL <br />A. Install materials in accordance with manufacturer's instructions, approved submittals and in <br />proper relationship with adjacent construction. <br />3.4 MIXING <br />A. StoGuard: <br />1. Sto Gold Fill: Mix with a clean, rust-free electric drill and paddle to a uniform <br />consistency. Do not thin, or dilute with water. <br />2. Sto AirSeal: Mix with a clean, rust-free electric drill and paddle to a uniform <br />consistency. Do not thin, or dilute with water. <br />3. Sto EmeraldCoat: Mix with a clean, rust-free electric drill and paddle to a uniform <br />consistency. Do not thin, or dilute with water. <br />B. StoPowerwall Stucco: Refer to mix instructions on packaging. Use only the amount of water <br />necessary for a workable mix. Use of excess water is detrimental to performance. <br />C. Adhesive and Base Coats for Sto Crack Defense and Foam Build-Outs: Refer to applicable <br />Sto Product Bulletin for selected adhesive and base coat materials. <br />D. Primer: Mix with a clean, rust-free high-speed mixer to a uniform consistency. <br />E. Finish: Mix with a clean, rust-free high-speed mixer to a uniform consistency. A small <br />amount of water, up to 12 oz (0.4 L) may be added to adjust workability. Limit addition of <br />water to amount needed to achieve the finish texture. <br />F. Mix only as much material as can readily be used. <br />G. Do not add lime, anti-freeze compounds, or other additives to any of the materials. <br />3.5 AIR/MOISTURE BARRIER INSTALLATION <br />A. The following instructions are applicable to: <br />1. Exterior or Exposure I Plywood per PS-1. <br />2. OSB (Oriented Strand Board) per PS-1 or PS-2. <br />3. Glass Mat Faced Gypsum Sheathing per ASTM C 1177. <br />4. Concrete and Concrete Masonry surfaces. <br />B. Transition Detailing: Detail transition areas with Sto RapidGuard (static joints and seams) or <br />StoGuard Transition Membrane (dynamic joints and seams) to achieve air barrier continuity. <br />For illustrations of installation, refer to Sto Guide Details and Sto RapidGuard Installation <br />Guide or StoGuard Transition Membrane Installation Guide (www.stocop.com). <br />C.
