INSTALLATION INSTRUCTIONS

NOTICE TO INSTALLER:
LIMITED WARRANTY IS EFFECTIVE
ONLY IF THESE INSTALLATION
INSTRUCTIONS ARE FOLLOWED IN
EVERY RESPECT. MAKE CERTAIN
THESE INSTRUCTIONS ARE PLACED
IN THE HANDS OF THE FLOOR
OWNER.

CRI / Carpet Rug Institute 104. In

addition to the specific instructions
detailed here, the Carpet and Rug
Institute Standard for Installation of
Commercial Carpet, CRI 1-04, must
be closely followed as basic minimum
requirement for floor preparation and
installation on all carpet installations.
Please note that many of the
Statguard® Modular Carpet installation
requirements, detailed here may
actually exceed those in the CRI
Installation Standard because of specific
product characteristics.

Attention to detail during floor
preparation and installation is essential
to take full advantage of Statguard’s
performance potential.

Testing concrete.

The general contractor or installer
should perform tests for moisture and
alkalinity before installation. Test for
moisture or vapor emission with a
calcium chloride kit. We recommend the
use of Statguard
Detection Test Kit item # 81305. This kit
meets ASTM F1869-98. Call Statguard®
Floorings @

* Excessive moisture or alkalinity can
contaminate the Conductive Adhesive #

81303, or damage the carpet backing,

adversely affecting indoor air quality.

Installing Statguard® ESD Modular
Carpets over excessive moisture can
also void product warranties.

Moisture vapor emission should not
exceed three pounds per 1,000 square
ft. per 24 hours as determined by
the proper application of the calcium
chloride test. Keep in mind that
test protocol now requires that the
test environment be similar to the
environmental conditions anticipated
when the space is occupied. That
generally means the building must be
enclosed and climate controlled for
at least 72 hours prior to testing. Also
the test must also be in place a full 72
hours to develop accurate readings. It
is recommended to conduct a test for
every 1,000 square feet.

Concrete moisture. Moisture emission
rate should be determined with proper
application of the calcium chloride
test. Vapor emission levels should not
exceed three pounds as determined
by the proper application of the
calcium chloride test. If the concrete
slab moisture test is higher than
three pounds, STOP the installation
immediately.

Alkalinity. Alkalinity should be
determined with pH testing strips and
distilled water. Test for alkalinity by
scraping an indention in the concrete
and pour a small amount of distilled
water into the indention. Use pH test
papers or test strips to check the pH
of the water. If the chemical pH is over
nine on a scale of 14, wash floor with
a mixture of 30% vinegar and 70%
water. Rinse floor with water and retest.
Repeat, if necessary, until pH is seven
or over, but less than or equal to nine.
If the chemical pH is over nine, STOP
the installation immediately. Detailed
procedures for conducting these tests
are included in the test kit.

Primers:

To assure maximum performance, floor
primers and Conductive Adhesive #

81303 have been specially formulated

for this specific backing type. Use
of any other primer or Conductive
Adhesive # 81303 can cause a
breakdown in the composition of the
backing material and will void the
product warranty. Unless specifically
addressed in these instructions,
Statguard® ESD Modular Carpet should
only be installed with the following
products by ReSource Technologies
and Statguard® Flooring:

•ReSource3300,primerbarriercoating

•Statguard#81303, pressure sensitive

Conductive Adhesive

ReSource 3300 barrier coating is
recommended as an excellent way to
assure a proper, long-term Conductive
Adhesive # 81303 bond for any carpet
installation. ReSource 3300 barrier
coating is recommended to be used
on:

•Newconcreteslabs

•Levelingorpatchingcompounds

•Existingadhesives

Preparing the Sub-Floor

Any sub-floor onto which carpet is to be
installed should be carefully inspected
to assure that proper bonding of the
carpet to the floor could be achieved.
Proper adhesion requires that the
sub-floor surface be clean, dry, level,
free from dust, oil, paint, greases,
sealer, paint, old adhesives and floor
finishes, or any other foreign material.

The level should meet the same
standards as outlined in the American
Concrete Institute (ACI) specifications
for Concrete Building (ACI 301-84)

-11.7.3 troweled finish and 11.9.1

finishingtolerances.Leveling

compounds should be Portland cement
based. Gyp-Crete is not recommended

.

as a suitable substrate for Statguard®
ESD Modular Carpets.

New concrete slabs. Before priming
with the recommended ReSource
Technologies 3300 barrier coat, new
concrete slabs must be fully cured,
which usually requires about 90 days.

Newconcretemustalwaysbetested

for moisture emission and excessive
alkalinity.

Existing concrete slabs. It is
recommended to prime with ReSource
Technologies 3300 barrier coat if
chemicals were used to remove the old
finish. Old floor covering adhesives
paint sealers, grease, oil, and other
foreign materials should be removed
then covered with a barrier coat to avoid
possible adhesive contamination.

Keep in mind that changing floor ­covering products can also change the
rate of vapor emission coming from
old concrete slabs. This change could
create moisture problems. Moisture
testing must be done prior to installation
of Statguard® ESD Modular Carpets to
make certain vapor emission rate will
not become a problem.

Patching compounds. Cracks and
holes must be patched with approved
patching compounds. Most must
be mixed with latex rather than
water to avoid cracking or chipping.
Recommended patching compounds

includeLev-L-Astic,lFixall,Armstrong

5-180, Webpatch, or ARDEX K-15T4.
Ardex K-15T4 is the only patching
compound currently recommended that
is designed to be mixed with water, per
manufacturer’s instructions, and still
provide an excellent substrate.

Barrier patching. Once the sub-floor
is patched and patched areas have
dried, remember it is recommended to
seal with ReSource Technologies 3300
barrier coat.

Over vinyl tile. Replace or patch
loose tiles and remove wax coating.
It’s extremely important to remember
that cutback adhesives will damage the
backing on Statguard® ESD Modular
Carpets. ReSource Technologies 3300
barrier coat is recommended to be
used to prevent backing contamination.
Excessive cutback adhesives should
be reduced / knocked down before
application of the 3300 barrier coat.

Over wood. Sand finish down to bare

wood. Repair loose or broken boards
and other defects for a smooth surface.

Over tongue and groove. Securely
fasten boards to sub-floor with 8-D
cement coated screw nails. Sand
cupped or uneven wood strips until
level. If boards are worn or badly
cupped, cover with 5/8 inch (1.6 cm)
exterior grade AD plywood secured with
8-D cement coated screw nails spaced
6 inches (15.2 cm) apart. Sand seams
smooth.

Other wood floors. Cover single
layer plywood or particleboard floors
with 5/8 inch (1.6 cm) exterior grade
AD plywood. Secure with 8-D cement
coated screw nails spaced 6 inches
(15.2 cm) apart. Sand seams smooth.
If double layered floors are sound, apply
latex top coat to make smooth and
level. Sand if necessary.

Granolithic, terrazzo, marble,
ceramic. Patch or fill cracks and

irregularities, including ceramic tile
grout lines, with latex-mixed patching
compound. Remove surface gaze by
rough sanding.

Before starting

Construction site. Far too often,

carpet products are installed before
the construction site is reasonably
accessible or ready. Carpet can be
permanently damaged or stained during
the construction process. Please
understand that Statguard® Flooring will
not be held responsible for any staining,
soiling, contamination or damage
caused by building construction. Both
the installer and the general contractor
should consider the risks when installing
carpet before other construction site
trades have completed their work.
Paints or lacquer over spray, spills,
excessive soiling are among a variety of
possible job site contaminates that will
void the owner’s product warranty.

Temperature and lighting. Job site and
all products or materials to be used in
the installation must be preconditioned
at a temperature between 60 degrees
F (15.50°C) and 95 degrees F (350°C)
for a period of 48-72 hours before
installation begins. The temperature
must remain within this range

throughouttheinstallation.Lighting

must be in service to allow inspection
under specified lighting conditions.

Correct carpet. Installer must
verify carpet conforms to owners
specifications, including correct product
and color. Each carton contains 20 tiles

(or5.98squareyards).Labelsoneach

carton contain, important information
including product, color, and dye lot.

Do not mix dye lots or run numbers in
the same area. Statguard® Flooring
will not be responsible for sorting
or reinstalling mixed lots. Once an
incorrect color or product has been
installed, Statguard Flooring will not
be held responsible or assume related
costs for corrective action.

Tools required. Inch/metric steel
measuring tape, white chalk line, carpet
knife, straight edge, and paint roller or
straight edged trowel (for Conductive
Adhesive # 81303).

NOTE: Statguard® ESD Modular Carpet

requires Special Installation

using Full Spread Conductive

Releasable Adhesive and Braided

Ground Straps.

Grounding ESD Modular
Carpets:

It is necessary to properly ground the
Statguard® Conductive Floor Adhesive
in order to provide proper ground to the
Statguard® Floor Tile. We recommend
that this be done using the Statguard®
braided ground strap which is supplied
with the adhesive.

Before applying adhesive and laying
tiles, locate a properly grounded
electrical receptacle that you will use
as your source of building ground. It
is recommended to have this loca tion
in the middle of the longest edge or
sensibly chosen to give equal distance
to ground from the flooring space. If
multiple braided ground straps are used,
space them evenly as needed. The
number of ground wires will vary with the
number of square feet. We recommend
one braided ground strap for every
2,000 square feet.

Disconnect the power at the electrical
panel for the receptacle being used.
Remove faceplate of outlet receptacle.
