The plywood must be supported along all edges, and adequately fastened to all bearings by means of countersunk wood screws, or screw nails equivalent to 8d ring shank nails spaced at 6 inches (152 mm) on center, or as otherwise required by the applicable code. The nails must have a minimum penetration into the beams or joists supporting the plywood as required by the applicable code. The plywood surface must be clean, dry and free of all foreign materials such as paint, grease, oil and dust. Cracks in the plywood and all panel butt joints are to be sealed using a caulking compound. 4.2.3 Steel: Steel surfaces, having sufficient rigidity to avoid excessive deflections or being solidly backed by a rigid substrate, must be cleaned of all dust, grease, oil, silicone, loose paint, etc. The surface must be sufficiently roughened to assure a good bond by sanding, grinding, etc., and the resultant dust must be carefully removed. 4.3 Class A Roof Covering over Plywood Deck: a. The plywood is described and installed as set forth in Section 4.2.2, at a maximum slope of 1/4:12 (2.1%). Plywood panel joints must be filled with joint compound consisting of one part Resistite paste to three parts Resistite powder, mixed by weight. Total minimum thickness is 9/32 inch (7.1 mm). b. One layer of Type IV, asphalt -coated, fiberglass base sheet complying with ASTM D 2178 must be applied to the plywood. The sheets must be nominally 36 inches (919 mm) wide by 56 yards (51.2 m) long and must weigh a minimum of 10.5 pounds per 100 square feet (0.5 kg/m2). The base sheet must terminate 2 inches (51 mm) from the perimeter, protrusions and other flashing areas, and must be lapped 2 inches (51 mm) at joints. c. Metal flashing must not be less than 0.019-inch (0.48 mm) (No. 26 galvanized sheet gage) corrosion - resistant steel and must be degreased before installation.Thebase sheet must lap over the horizontal flange of installed vents. d. A mixture of one part Resistite paste and 2.25 parts Resistite powder, by weight, must be applied to all exposed surfaces and extend 4 inches (102 mm) onto the adjacent base sheet. Coverage must be a minimum of 19 pounds per 100 square feet (0.9 kg/m2). e. Perimeter and flashing areas must receive a coating of Neobond II membrane liquid at a minimum rate of 30 pounds per 100 square feet (1.5 kg/m2). Loose -woven jute fabric, nominally 0.035 inch (0.9 mm) thick and weighing 7 ounces per square yard (237 g/m2), must be embedded into the wet Neobond II. The combined thickness of Neobond II and fabric must be approximately 0.07 inch (1.8 mm). Each coating must be dry (this normally requires 12 to 16 hours) before recoating. f. Flat (field) areas must receive a coat of Neobond II membrane liquid at a rate of 21 pounds per square (1 kg/m2). Random strands of fiberglass mat, weighing 1/4 ounce per square foot (76 g/m2), must be embedded into the wet Neobond II. The combined thickness of Neobond II and fiberglass must be approximately 0.050 inch (1.3 mm). Each coating must be dry (this normally requires 12 to 16 hours) before recoating. g. An additional coat of Neobond II is applied, to fill voids in the jute and fiberglass fabrics, at the rate, respectively, of 6 pounds and 5 pounds per square foot (29 kg/m2 and 24 kg/m2). Thickness of the membrane system must be 0.085 inch (2.1 mm) at perimeter and flashing areas and 0.062 inch (1.6 mm) in the field area. About six hours are needed for cure. h. A mixture of one part N-38 paste and five parts Standard Neotex powder, by weight, must cover the surface at a rate of 80 pounds per 100 square feet (3.9 kg/m2). The approximate dry thickness must be 0.090 inch (2.3 mm). After curing for a minimum of 12 hours, a second application at a rate of 52 pounds per 100 square feet (2.5 kg/m2) yields a dry thickness of 0.060 inch (1.5 mm). The total application is 132 pounds per 100 square feet (6.4 kg/m2), for a total dry thickness of 0.150 inch (3.8 mm). I. After the Standard Neotex has cured for a minimum of 12 hours, a topping mixture of one part Resistite paste and 2.75 parts Resistite powder, by weight, must be troweled on at a rate of 18.5 pounds per 100 square feet (0.9 kg/m2), yielding a minimum dry thickness of 0.016 inch (0.4 mm). After curing to a dry state for a minimum of three hours, another topping is applied using one part Resistite paste to 2.1 parts Resistite powder, at a rate of 12 pounds per 100 square feet (0.6 kg/m2), yielding a minimum dry thickness of 0.010 inch (0.25 mm). Total topping application must yield a minimum dry thickness of 0.028 inch (0.71 mm). j. After the topping application has cured to a dry state for a minimum of three hours, two coats of AJ-44 dressing must be roller -applied, at a rate of 150 square feet per gallon (3.7 m2/L), yielding a minimum dry thickness of 0.005 inch (0.13 mm). The first coat must be cured dry (this normally requires two to four hours) before application of the second coat. Total thickness of Items a through j of Section 4.3, excluding base sheet and perimeter/flashing bond coating, must be a minimum 0.245 inch (6.2 mm) at flat areas and 0.268 inch (6.8 mm) at perimeter areas. 4.4 Class A Roof Covering Over Concrete and Steel Decks: The roof deck must be concrete or steel prepared as noted in Section 4.2 of this report, with a minimum slope of 1/2:12 (4%). For concrete substrates, the base sheet must be bonded to metal flashing at the perimeter. For steel decks, the base sheet is optional. If a base sheet is used on steel decks, it must be bonded directly to the steel deck at the perimeter or installed with a metal flashing as for the concrete surface. The roof covering must be installed in accordance with items b through j of Section 4.3, above. 4.5 One -hour Fire -resistance -rated Construction: The Dex-O-Tex Weathenvear Roof Deck covering installed as described in this report over 5/e-inch-thick (15.9 mm) exterior -grade plywood with 2-inch-by-8-inch (51 mm by 203 mm) joists spaced 16 inches (406 mm) on center, with all plywood joints blocked, may be substituted for the double wood floor described in Footnote 13 of Table 7-C of the UBC and Item 13 and footnote m of Table 721.1(3) of the 2021, 2018, 2015 and 2012 IBC [Item 13 and footnote m of Table 720.1(3) of the 2009 and 2006 IBC].
