2.0 USES
Dex-O-Tex Weatherwear Roof Deck Covering is a walking
deck and Class A roof system for use over plywood,
steel or concrete decks. The system is also used as a
component of a one -hour fire -resistance -rated roof
assembly.
3.0 DESCRIPTION
Dex-O-Tex Weatherwear roof deck covering is a
multilayered, trowel -applied, waterproof roof coating that is
subjected only to normal foot traffic. The system consists
of a series of troweled coatings that form, successively, an
elastic latex membrane, an integral composition flashing,
and a flexible rubber cement traffic surface, made of
Resistite paste, Resistite powder, Neobond II membrane
liquid, N-38 paste, and Standard Neotex powder. A base
sheet separates the Dex-O-Tex application from the
surface it covers, permitting it to "float' over normal
building cracks and movement. Dex-O-Tex Weatherwear
components are all combinations of liquid rubber latex
polymers incorporating dehydrating powders, vulcanizers,
and special aggregates. The total thickness of the material
is 3/16 inch to 114 inch (4.8 mm to 6.4 mm).
4.0 INSTALLATION
4.1 General:
Installation of the Dex-O-Tex Weatherwear must be in
accordance with the manufacturer's published installation
instructions, the applicable code and this report. The
manufacturer's installation instructions must be available
on the jobsite during application. Liquid components have
a shelf life of one year and must be stored at temperatures
above 320F (0°C). The system must be installed only when
the ambient temperature is above 320F (0°C). Materials
must not be applied if precipitation is occurring or
expected.
4.2 Preparation of Substrates:
Structurally sound, clean, dry substrates listed above must
be prepared, as described below, prior to the application of
the finish material.
4.2.1 Structural Concrete: The surfaces must be clean
and free of standing water. All holes, joints and cracks
must be pointed flush with portland cement mortar, and all
high spots cut or ground off to provide a smooth, even
surface. Before the material is applied, the substrate must
be carefully swept, or blown clean by high-pressure air to
remove all dust or foreign material. Special care must be
taken in the preparation and cleaning of all corners and
edges. Foreign materials such as paint, grease and oil
must be removed by either grinding or sandblasting, with
new concrete surfaces acid -etched. Large areas to be
covered are required to have control joints at maximum
intervals not to exceed 20 feet (6096 mm) on center, with
the control joint system worked out to meet all known deck
stress —concentration points. The control joints must be cut
in the same manner as for standard concrete construction,
and then caulked.
4.2.2 Plywood Base Material: Plywood substrates must
be minimum a/a-inch-thick (15.9 mm) exterior -grade
plywood, having a maximum span of 16 inches (406 mm).
and with tongue -and -groove edges and ends blocked or all
edges blocked, and face grain perpendicular to supports.
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.

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).
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.
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. The base sheet must lap over the
horizontal flange of installed vents. -
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
