film is factory -printed and top -coated with a PVC/acrylic
finish. The membrane complies with ASTM D4434, Type It.
The membrane is produced in a variety of colors and
patterns and is available in rolls of various widths and
lengths. The membrane weighs approximately 55 ounces
per square yard (1864 g/m2) and is nominally 0.060 inch
160 mils (1.5 mm)] thick.
3.2.2 Adhesives:
3.2.2.1 Duradek D763: A white -colored, water -based,
liquid adhesive with a shelf life of six months when stored in
unopened containers at temperatures between 45' and
80'F (10' and 26.7'C).
3.2.2.2 Duradek D811-23-S and Duradek D811-23-W: A
yellow -colored, liquid contact adhesive with a shelf life of
six months when stored in unopened containers at
temperatures between 45' and 80'F (10' and 26.7'C).
3.2.2.3 Mapei Ultra Flex 2: A single -component, polymer -
modified thin -set mortar with a shelf life of one year when
stored in unopened containers at 73'F (23°C) and
50 percent relative humidity.
3.2.3 Substrates:
3.2.3.1 Plywood: Minimum s/s-inch-thick (15.9 mm)
exterior -grade with tongue -and -groove edges or blocked
edges, complying with US Department of Commerce
Product Standard PS-1 or PS-2.
3.2.3.2 USG Durock Cement Board Next Gen: Minimum
nominally t2-inch-thick cement panel, manufactured by
United States Gypsum Company.
3.3 Impact Resistance:
The Duradek Ultra System described in this report complies
with requirements for impact resistance in accordance with
ASTM D3746,
4.0 INSTALLATION
4.1 General:
Installation of the Duradek Ultra system must be in
accordance with the report holder's published installation
instructions, the applicable code and this report. The report
holders installation instructions must be available on the

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.
