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 092423-29 <br /> <br />the adjacent stucco surfaces to an approximate thickness of 1/8 inch (3 mm). <br />Immediately embed the reinforcing mesh in the wet base coat. Trowel from the <br />center to the edges of the mesh to avoid wrinkles and remove excess base coat. <br />Overlap mesh seams minimum 2-1/2 inches (64 mm). Overlap mesh onto adjacent <br />stucco wall surfaces minimum 2-1/2 inches (64 mm) at terminations of the foam <br />build-out and feather onto the stucco wall surface. Alternatively, If Crack Defense is <br />used apply Crack Defense with its reinforcing mesh continuously from the stucco wall <br />surface over foam build-outs. <br />D. Crack Defense: <br />1. Apply base coat over the moist cured stucco (and foam build-outs if not already <br />reinforced with mesh) with appropriate spray equipment or a stainless-steel trowel to <br />a uniform thickness of approximately 1/8 inch (3 mm). <br />2. Work horizontally or vertically in strips of 40 inches (1016 mm), and immediately <br />embed the mesh into the wet base coat by troweling from the center to the edge of <br />the mesh. <br />3. Overlap mesh not less than 2-1/2 inches (64 mm) at mesh seams and at overlaps of <br />detail mesh. <br />4. Feather seams and edges. Avoid wrinkles in the mesh. <br />5. The mesh must be fully embedded so that no mesh color shows through the base <br />coat when it is dry. <br />6. Re-skim with additional base coat if mesh color is visible. Do not install base coat or <br />mesh over joints or accessories in the stucco wall assembly. <br />E. Primer Installation: <br />1. StoPrime Hot: Moist cure stucco for a minimum of 48 hours. Allow stucco to dry an <br />additional 48 hours, then apply primer evenly with brush, roller or proper spray <br />equipment over the clean, dry stucco and foam build-outs, and allow to dry. Final age <br />of primed stucco application must be minimum 7 days before application of finish. <br />2. StoPrime Sand: Moist cure stucco for a minimum of 48 hours. Wait until stucco is 28 <br />days old or the pH level of the surface is below 10 before applying primer. Final age <br />of primed stucco application must be minimum 28 days before application of finish or <br />pH must be below 10. <br />3. StoPrime: Moist cure stucco for a minimum of 48 hours. Wait until stucco is 28 days <br />old or the pH level of the surface is below 10 before applying primer. Final age of <br />primed stucco application must be minimum 28 days before application of finish or <br />the pH must be below 10. <br />F. Finish Installation: <br />1. Apply finish to minimum 28-day old stucco or primed stucco and foam build-outs, or <br />when pH of stucco surface is less than 10. If StoPrime Hot is used as the primer the <br />primed stucco/foam build-out surfaces need only be minimum 7 days old. Apply finish <br />by spraying or troweling with a stainless-steel trowel, depending on the finish <br />specified. Follow these general rules for application of finish: <br />a. Avoid application in direct sunlight. <br />b. Apply finish in a continuous application, and work a wet edge towards the <br />unfinished wall area. Work to an architectural break in the wall before stopping <br />to avoid cold joints. <br />c. Weather conditions affect application and drying time. Hot or dry conditions <br />limit working time and accelerate drying. Adjustments in the scheduling of work <br />may be required to achieve desired results; cool or damp conditions extend <br />working time and retard drying and may require added measures of protection <br />against wind, dust, dirt, rain and freezing. Adjust work schedule and provide
