All rights reserved. Page 1 of 4 ESR-2151 I Most Wide/yAccepted and Trusted Page 2 of 4 jobsite during application. Installation is limited to conditions when the weather is dry and the ambient air temperature is a minimum of 45°F (7.2°C). Materials must not be applied if precipitation is occurring or expected during application. 4.2 Preparation of Substrates: Substrates must be structurally sound, clean and dry, and must be sloped a minimum of 1/4 inch per foot (2 percent slope). 4.2.1 Plywood: Plywood must be applied to framing in accordance with the requirements of the applicable code. All unsupported edges must be blocked. All penetrations through and terminations of the sheathing must be protected with metal flashing in accordance with the requirements of the applicable code and the report holder's published installation instructions. 4.2.2 USG Durock: Where USG Durock is used as a substrate, it must be installed over a plywood substrate complying with, and installed in accordance with, Sections 3.2.3.1 and 4.2.1. See Footnote 3 of Table 1 for additional installation details for this substrate using Mapei Ultra Flex 2 polymer -modified thin -set mortar and screws. 4.3 Membrane Installation: The membrane must be adhered to the substrate with either Duradek D763, Duradek D811-23-S or Duradek D811-23-W adhesive. Duradek D763 must be applied to the substrate with either a U-notched trowel having 1/32-inch-deep-by-1/16-inch-wide (0.8 by 1.6 mm) notches spaced 1/32 inch (0.8 mm) apart or a textured roller. The minimum coverage is 1 gallon per 190 square feet (1 L/4.66 m2). Duradek D811-23-5 and Duradek D811-23-W must be applied with either a brush or a roller at a coverage rate of 1 gallon per 70 to 90 square feet (1L/1.71 m2 to 1L/2.21 m2). The minimum application temperature for both adhesives is 45°F (7.2°C). A minimum 2-inch (51 mm) width of Duradek D811-23-5 or Duradek D811-23-W adhesive must be used at the perimeter of the deck and on walls, edges and right-angle corners. Membrane seams must be overlapped a minimum of 314 inch (19.1 mm) at edges and ends, and heat -fused with a hot-air seaming tool. Exposed edges, posts and trim strips must be sealed with sealant in accordance with the report holders published installation instructions. 4.4 Method of Repair. A portion of the membrane larger than the affected area must be removed and a new piece of material must be prepared that is 1 1/2-inch (38 mm) larger in dimension than the piece removed. Duradek D763, Duradek D811-23-S or Duradek D811-23-W adhesive must be applied to the substrate and the patch must be placed into the space so it overlaps the existing sheet by 314 inch (19 mm). The patch must be welded to the existing sheet using a hot-air seaming tool. 4.5 Wind Resistance: The roof deck construction over which the Duradek Ultra system is installed must be designed to resist the minimum design wind pressures set forth in the applicable code. The allowable wind uplift pressures for the roof assemblies are noted in Table 1. Metal edge securement systems must be listed in accordance with 2011 edition of ANSI/SPRI/FM 4435 ES-1, and designed and installed for wind loads in accordance with 2018 and 2015 IBC Section 1504.5 and 2018 and 2015 IBC Chapter 16 [2003 edition of ANSI/SPRI/FM 4435 ES-1, and designed and installed for wind loads in accordance with 2012 and 2009 IBC Section 1504.5 and 2012 and 2009 IBC Chapter 16]. 4.6 Roof Covering Classification: See Table 1 for fire -classified assembly details. 5.0 CONDITIONS OF USE The Duradek Ultra walking deck and roof covering system described in this report complies with, or is a suitable alternative to what is specified in, those codes listed in Section 1.0 of this report, subject to the following conditions: 5.1 Installation must comply with this report, the report holders published installation instructions and the applicable code.
