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 092423-24 <br /> <br />1. Sto Gold Fill with StoGuard Mesh: Apply 9 inch (229 mm) wide StoGuard Mesh at <br />rough openings. Immediately apply Sto Gold Fill by spray or trowel over the mesh and <br />spread smooth with a trowel to completely cover the mesh (refer to Sto Detail <br />22s.20M). <br />2. Sto EmeraldCoat or Sto AirSeal with StoGuard Fabric: Apply coating liberally by spray <br />or roller to corners of openings, immediately place StoGuard RediCorners in the wet <br />coating, and apply additional coating over the RediCorners to completely embed <br />them. After all corners have been completed apply coating liberally to the entire <br />rough opening, immediately place StoGuard Fabric in the wet coating, smooth any <br />wrinkles with a brush or roller, and apply additional coating over the fabric to <br />completely embed it. Overlap all seams minimum 2 inches (51 mm). Once completed <br />top coat with additional coating as needed to completely seal the surface. Allow to dry <br />and inspect for pinholes or voids. If pinholes or voids are present, seal with additional <br />coating or Sto RapidGuard. <br />3. Sto RapidGuard: Apply a fillet bead of material with a caulking gun at interior corners <br />inside the opening to seal jamb/sill and jamb/head seams. Apply material in a zig-zag <br />pattern along sill, jams, and head to form a generous bead of material along the <br />surface to be covered. Use a 6 inch (152 mm) wide plastic drywall knife to spread the <br />material to a uniform thickness of 12 to 20 mils (0.3 to 0.5 mm) before the material <br />skins. Treat the entire rough opening surface in this manner and overlap onto the <br />face of the sheathing 2 inches (51 mm) minimum all the way around. <br />D. Sheathing Joint Treatment: <br />1. Sto Rapid Guard: Apply to properly installed sheathing, joints butted for gypsum <br />sheathing, and joints gapped for plywood and OSB sheathings (wood-based sheathing <br />typically requires 1/8 inch (3 mm) spacing at edge and end joints). Apply a thick bead <br />of Sto RapidGuard with a caulking gun along sheathing joints, or apply in a zig-zag <br />pattern across and down the joints. Spread to a uniform thickness of 20 to 30 mils <br />(0.5 to 0.6 mm) before the material skins. Spread 1 inch (25 mm) beyond the <br />sheathing joint on each side. Follow the same procedure for inside and outside <br />corners. <br />2. Sto Gold Fill with StoGuard Mesh: Place 4 inch (102 mm) wide mesh centered along <br />sheathing joints and minimum 9 inch (229 mm) wide mesh centered and folded at <br />inside and outside corners. Immediately apply Sto Gold Fill by spray or trowel and <br />spread smooth with a trowel to completely cover the mesh. <br />3. Sto AirSeal or Sto EmeraldCoat with StoGuard Fabric: Apply coating liberally by spray <br />or roller along sheathing joints and immediately place 4 inch (102 mm) wide fabric <br />centered over the joints into the wet coating, and 6 inch (152 mm) wide fabric <br />centered and folded at inside and outside corners into the wet coating. Smooth any <br />wrinkles with a brush or roller and apply additional coating to completely embed the <br />fabric. Overlap seams minimum 2 inches (51 mm). <br />E. Air/Moisture Barrier Coating Installation: <br />1. Plywood and Gypsum Sheathing: apply waterproof coating by spray or roller over <br />sheathing surface, including the dry joint treatment, rough opening protection, and <br />transition areas, to a uniform thickness of 10 wet mils (0.254 mm) in one coat (Sto <br />EmeraldCoat) or 50 wet mils (1.27 mm) in one coat (Sto Air Seal). Use 1/2-inch (13 <br />mm) nap roller for plywood. Use 3/4-inch (19 mm) nap roller for glass mat faced <br />gypsum sheathing. Protect from weather until dry. <br />2. OSB Sheathing: apply waterproof coating by spray or with a 3/4-inch (19 mm) nap <br />roller to sheathing surface to a uniform thickness of 10 wet mils (0.254 mm) (Sto <br />EmeraldCoat) or 50 wet mils (1.27 mm) in one coat (Sto Air Seal). Protect rough <br />openings, joints, and parapets, then apply a second coat of waterproof coating.
