The manufacturer’s published installation instructions must be available at the jobsite at all times during installation. ESR-1233 | Most Widely Accepted and Trusted Page 3 of 6 4.2 Substrate Preparation: StoGuard® water-resistive barrier coating systems are installed on the exterior side of vertical exterior walls. Surfaces must be free of all bond-inhibiting materials, including dirt, oil and other foreign matter. StoGuard® water-resistive barrier coating systems must be applied only when the surface and ambient temperatures are 40°F (4°C) and rising during the application and drying period. Working time will decrease as surface and ambient temperatures increase. StoGuard® water-resistive barrier coating systems must not be installed on damp surfaces, below-grade surfaces, or on surfaces subject to water immersion. Damaged sheathing must be removed and replaced. Sheathing must be installed as required by the applicable code. StoGuard® water-resistive coating system must be covered with an exterior wall finish complying with the requirements of the applicable code or a current evaluation report. Sto Gold Fill® must be troweled over all sheathing joints, rough openings, and inside and outside building corners. Sto Detail Mesh shall be immediately embedded in the Sto Gold Fill® and troweled smooth. Sheathing joints require a minimum 4-inch (101 mm) width of mesh. Rough openings and corners require a minimum 9-inch (228 mm) width of mesh. Fastener heads and surface defects must be spot- coated with Sto Gold Fill®. The system must not be applied over irregular surfaces. The substrate to be coated must be continuous, without joints, holes, etc., exceeding 1/32 inch (0.8 mm) in size. Surface defects larger than 1/32 inch (0.8 mm) must be treated with Sto Gold Fill® prior to application of Sto Gold Coat®. The application thickness of Sto Gold Fill™ must not exceed 1/16 inch (1.6 mm). StoGuard RapidSeal is applied with a caulking gun and spread with a plastic drywall knife to a minimum thickness of 12 mils [0.012 inch (0.305 mm)] over 2-inch-wide (51 mm) StoGuard Mesh centered over sheathing joints, except for corners where 4-inch-wide (102 mm) mesh is used. At rough openings the material is spread over the entire rough opening and 4-6 inches (102-152 mm) onto the sheathing surface. Rough openings do not require the mesh. Use of the StoGuard RapidSeal is limited to use over plywood and glass mat faced gypsum sheathing as described in Section 3.3 of this report. Use of the StoGuard RapidSeal with Sto EmeraldCoat or Sto VaporSeal is outside the scope of this report. StoGuard RapidFill is applied with a caulking gun and spread with a plastic drywall knife over sheathing joints, and inside and outside corners, to a minimum thickness of 20 mils (0.5 mm), 1 inch beyond the sheathing joint on each side. After drying it is top coated with any of the StoGuard water-resistive coatings. StoGuard Fabric may be used in lieu of Sto Gold Fill as a joint treatment. Sto Gold Coat, Sto EmeraldCoat, or Sto VaporSeal™ is applied by spray, brush or roller to the joint area, and StoGuard Fabric is immediately embedded in the wet material by placing the fabric and then brushing or rolling over it. After drying, a second coat of Sto Gold Coat, Sto EmeraldCoat, or Sto VaporSeal is applied over the joint as described in Section 4.3, 4.4, or 4.5, respectively. 4.3 Sto Gold Coat® Application: 4.3.1 Sto Gold Coat® Application over Exterior Gypsum Sheathing, Glass Mat Faced Gypsum or Exterior Plywood: The substrate must be prepared as described in Section 4.2. Sto Gold Coat® must be applied with a nap roller in a single, uniform coat to a wet thickness of 10 mils [0.01 inch (0.25 mm)]. For application over glass mat faced gypsum sheathing, a 3/4-inch (19.1 mm) nap roller must be used. For application over plywood and gypsum sheathing, a 1/2-inch (12.7 mm) nap roller must be used. The coating must not be applied in rainy conditions. 4.3.2 Sto Gold Coat® Application over Oriented Strand Board (OSB): A two-coat application of Sto Gold Coat® is required over OSB. The first coat of Sto Gold Coat® must be applied over the substrate prior to treatment of sheathing joints, rough openings, and corners. The second coat of Sto Gold Coat® must be applied to the prepared substrate, as described in Section 4.2, with a 3/4-inch (19.1 mm) nap roller. The substrate receiving the second coat of Sto Gold Coat® must be continuous, without joints, holes, etc., exceeding 1/32 inch (0.8 mm) in size. The second coat of Sto Gold Coat® must be applied over the treated surface in a single, uniform coating to a wet thickness of 10 mils [0.01 inch (0.25 mm)]. The coating must not be applied in rainy conditions. 4.3.3 Sto Gold Coat Application over Concrete and Concrete Masonry: The substrate must be prepared as indicated in Section 4.2 of this report. For concrete substrates, a single uniform coat is applied by spray or roller to a wet thickness of 10 mils [0.01 inch (0.25 mm)]. For concrete masonry substrates, two single uniform coats are applied by spray or roller to a wet thickness of 15 mils [0.015 inch (0.38 mm)] each, or there is one uniform spray application to a wet thickness of 30 mils [0.03 inch (0.76 mm)]. 4.3.4 Curing and Drying: Sto Gold Coat® must be dry to the touch and may be over-coated within two to four hours after application, under normal conditions. Drying time varies depending on temperature/humidity and surface conditions. A minimum of 24 hours is required before any adhesive attachment of exterior finish to the final StoGuard® system surface is made, if required. Surfaces must be protected from rain and freezing until completely dry. 4.4 Sto EmeraldCoat® Application: 4.4.1 Sto EmeraldCoat® Application over Sheathing: The substrate must be prepared as described in Section 4.2. Sto EmeraldCoat® is applied with a nap roller or appropriate spray equipment in a single uniform coat to a wet thickness of 10 mils [0.01 inch (0.25 mm)]. For application over glass mat faced gypsum sheathing and orientated strand board (OSB) a 3/4-inch (19.1 mm) nap roller is used. OSB sheathing may require touch-up with a second application of Sto EmeraldCoat® where wood strands are raised. Surfaces must be inspected and touched up as needed before installation of wall covering materials. For application over plywood and gypsum sheathing, a 1/2-inch (12.7 mm) nap roller is used. The coating must not be applied in rainy conditions. 4.4.2 Sto EmeraldCoat Application over Concrete and Concrete Masonry: The substrate must be prepared as indicated in Section 4.2 of this report. For concrete substrates, a single uniform coat is applied by spray or roller to a wet thickness of 10 mils [0.01 inch (0.25 mm)]. For concrete masonry substrates, two single uniform coats are applied by spray or roller to a wet thickness of 15 mils [0.015-inch (0.38 mm)] each, or there is one uniform spray application to a wet thickness of 30 mils [0.03 inch (0.76 mm)]. 4.4.3 Curing and Drying: Sto EmeraldCoat® must be dry to the touch and may be over-coated within two to four hours after application. Drying time varies depending on temperature/humidity and surface conditions. Surfaces must be protected from rain and freezing until completely dry.
