THE CITY OF SUNNY ISLES BEACH PROJECT NO. 21-1011 BUILDING DEPARTMENT RELOCATION TO ANNEX Project No. 21-1011 November 2024 092423-28 above and below doors and windows. b. Install one piece expansion joints at every 144 sq ft (13 sq m). c. Wire tie one piece expansion joints to lath at no more than 7 inches (178 mm) on center. d. Seal adjoining pieces by embedding ends in sealant. Make certain lath is discontinuous at or beneath joints. e. Inside and Outside Corners: Install corner lath at inside corners and corner bead at outside corners over lath. f. Attach through lath into solid substrate or framing at no more than 7 inches (178 mm) on center with appropriate fasteners. 5. Stucco Installation: a. Scratch Coat: Apply stucco with sufficient pressure to key into and embed the metal lath. Apply sufficient material, 3/8 or 1/2 inch (9 or 12 mm), to cover the metal lath and to permit scoring the surface. Score the stucco upon completion of each panel in preparation for a second coat. Score horizontally. b. Brown Coat: As soon as the first coat is firm enough to receive the second coat without damage, apply the second coat. Alternatively, moist cure the first coat up to 48 hours and dampen the scratched surface with water immediately before applying the second coat. Apply the second coat with sufficient pressure to ensure intimate contact with the first coat and as needed to bring the stucco to a uniform thickness that matches the grounds of the accessories. Use a rod or straight edge to bring the surface to a true, even plane. Fill depressions in plane with stucco. Final thickness of stucco shall be uniform throughout the wall area and shall be either 3/4 inch or 7/8 inch (19 or 22 mm), and shall not exceed 7/8 inch (22 mm). c. After the stucco has become slightly firm float the surface lightly with a darby or wood float to densify the surface and to provide a smooth, even surface. The proper time to float is when the wood float no longer sticks to the surface of the stucco. d. Moist cure after the stucco has set by lightly fogging for at least 48 hours. Fog as frequently as required during the 48-hour period to prevent loss of moisture from the stucco. Avoid eroding the stucco surface with excess moisture. If relative humidity exceeds 75 percent, the frequency of moist curing can be diminished. C. Foam Trim and Build-Outs: 1. Where foam build-outs terminate at a dissimilar material such as a window, door or other non-stucco surface, backwrap the foam build-out by installing detail mesh onto the terminating edge of the stucco. Embed the mesh in the foam trim adhesive. Allow the mesh to dangle until the back wrapping procedure is completed. 2. Install foam build-outs directly over hardened stucco with foam trim adhesive. Apply adhesive with the appropriate size notched trowel to the back of the insulation board and immediately place build-out in the proper location on the wall. Press firmly into place and trim or tool excess adhesive from ends and edges of foam trim for a smooth void-free connection to the stucco substrate. 3. After the adhesive has cured sufficiently to hold the build-out firmly in place, rasp the entire foam surface smooth. 4. Complete the back wrapping procedure by applying the foam trim base coat to the exposed edges of the foam build-out and minimum 2-1/2 inches (64 mm) onto the face. Pull the backwrap mesh around the foam build-out and fully embed it into the base coat. Use a corner trowel for neat straight corners. 5. Apply the base coat to the foam build-out and approximately 3 inches (76 mm) onto
