The manufacturer s published installation instructions must be available at the jobsite at all times during installation. The system must be applied over unpainted wood-based structural panels, water-resistant core gypsum sheathing, or Dens-Glass Gold sheathing attached to minimum 2-by- 4 wood studs having a minimum specific gravity of 0.50, such as Douglas fir larch, spaced at a maximum of 16 inches (406 mm) on center, or to minimum 43-mil [0.0478-inch (1.2 mm) base-metal thickness] galvanized steel studs spaced at a maximum of 16 inches (406 mm) on center. The substrates must be limited to those having planar irregularities not exceeding 1 / 4 inch (6.4 mm), and must be structurally sound, clean, dry and smooth, with all dust and deleterious materials removed. All materials must be installed by applicators approved by Sto Corporation. During application of any water-based materials, the wall surface and the surrounding air temperature must be 40 F (4.4 C) or higher. The EIFS materials must be protected from wind, rain, dust and freezing until fully cured. If water is added to mixtures for workability, the minimum amount of water must be used. Typical installation details are shown in Figure 5. The sheathing must be installed with all edges blocked and attached to the framing members in accordance with Table 1. Expansion joints are required at locations where the substrate changes, at floor lines in wood-framed construction in which lumber shrinkage will occur, where the EIFS abuts another material, and where structural movement is anticipated. Joints must be installed as specified by the registered design professional, builder or exterior coating manufacturer, in that order. The weep screed must be attached, at the bottom of the wall system, to wood-based sheathing with galvanized or zinc-coated 6d common nails at 12 inches (305 mm) on center, or through gypsum sheathing into steel studs with minimum No. 6 by 1 1 / 4 -inch-long (32 mm), Type S-12, corrosion-resistant buglehead screws along each stud. The water-resistive barrier described in Section 3.1.2.1.3 must be installed over the sheathing and weep screed prior to installation of the insulation board. 4.2 Sto RainScreen Class PB Exterior Insulation and Finish Systems with Drainage: 4.2.1 Drainage Insulation Boards: The drainage insulation boards must be oriented with the grooves running vertically and fastened in accordance with the fastening pattern shown in Figure 2, using the designated Windlock fastening system described in Section 3.1.2.1.5. All joints are tightly butted, and vertical joints must be staggered. 4.2.2 Base Coat: Before any coatings are applied, the entire surface of the installed insulation board must be leveled with a rasping board or power rasper. A base coat of Sto BTS-Plus is applied to the entire board surface with a stainless steel trowel, to a uniform thickness of approximately 1 / 16 inch (1.6 mm). 4.2.3 Reinforcing Fabric: After the base coat is installed, Sto Mesh is immediately placed against the wet base coat and troweled from center to edge. The Sto Mesh must be continuous around corners and lapped at least 2 1 / 2 inches (64 mm) along edges. Wrinkles must be avoided and the mesh must be fully embedded and covered. The base coat must be allowed to dry for 12 hours prior to application of the finish coat. 4.2.4 Finish Coat: A sealant, as described in Section 3.1.2.1.10, must be applied, prior to application of the finish coat at system terminations, exposed joints, floor lines of wood-framed construction, changes in building shape or roof line, substrate changes, expansion joints, and wall penetrations. After the base coat has dried, the factoryprepared StoLit or StoSilco Lit plaster finish material is thoroughly mixed, using a high-speed mixer, until a uniform workable consistency is achieved. Small amounts of water are permitted to be added for workability. The StoLit or StoSilco Lit plaster finish is then applied directly to the base coat, using a clean, stainless steel trowel. The final texture is achieved with a plastic or stainless steel trowel. The finish coat thickness must not be greater than the diameter of the largest aggregate, approximately 1 / 16 inch thick (1.6 mm). 4.3 Sto RainScreen II Class PB Exterior Insulation and Finish Systems with Drainage: 4.3.1 Drainage Mat: The drainage mat described in Section 3.2.2.1.4 is installed with mechanical fasteners in accordance with Table 1 and Figure 4 over the waterresistant barrier. 4.3.2 Insulation Boards: Before the insulation boards are placed over the drainage mat, Sto BTS-Plus adhesive described in Section 3.2.2.1.5 is applied to the back of the boards, using a stainless steel or plastic trowel having 1 / 2 -inch-by- 1 / 2 -inch (12.7 mm by 12.7 mm) notches, spaced at 2 1 / 2 inches (64 mm) on center. The adhesive ribbons are applied parallel to the short dimension of the insulation boards. The insulation boards are adhered to the drainage mat and substrate, with adhesive ribbons vertically to provide a drainage cavity, and with uniform pressure over
