Material Overview:
The
Ground Zero Electrostatics, Inc PolyStat static control
range of ESD Floor Coverings consist of materials designed
to specific resistance requirements and are categorized
into three groups; Antistatic, Static conductive and Conductive.
Installation of PolyStat ESD Vinyl's sheet goods is similar
to standard (non-ESD) Vinyl sheet goods with several important
differences. Pay particular attention to section Three
and Seven of this document! A overview of the differences
between PolyStat and standard Vinyl sheet good installation
are listed for your convenience:
- GZ-C2000 Conductive
adhesives are supplied with PolyStat ESD Vinyl and must
be used.
- Grounding mechanisms
consisting of Ground Zero Electrostatics, Inc Copper
or Brass foil grounding grid must be applied and grounded
Prior to spreading of adhesives. More information on
ground grid placement can be found on our Ground Grid
Placement Specifications
- Proper spread
rate of adhesive is critical, proper trowel dimensions
and rolling parameters must be used (see section 7).
- The GZ-C2000
adhesive used with PolyStat Flooring may be of slightly
lower bonding strength than standard vinyl adhesives,
as such proper use of recommended rolling procedures,
adhesive usage, adhesive spread rate and coverage must
be utilized, see section 7.)
- PolyStat ESD
Flooring can be installed by using the double drop method
(see section 7) when installing on hard troweled concrete
or substrates that are somewhat non-porous. Laying the
material into wet adhesive is acceptable on porous substrates,
however do not allow excessive adhesive "tack" when
applying in this manor.
- PolyStat ESD
Vinyl must be conditioned and relaxed prior to installation,
(see section 3) and temperature in room must be maintained
in the standard plant operating range 72 hours before,
during and after the installation.
Site and Material Preparation:
1. Perform
calcium chloride moisture emission testing on concrete
floors regardless of the age or grade level of the concrete.
Testing shall be performed around the perimeter of the
room and any area where concrete moisture emissions is
evident. GZ-C2000 adhesive has been successfully utilized
in conditions up to 8.0 lbs per 1000 sq/ft in a 24 hour
period and is fully warranted to moisture emissions as
high as 6 lbs per 1000 sq/ft in a 24 hour period (contact
Ground Zero Electrostatics, Inc prior to install if your
testing confirms moisture emissions over our 6 lb limit).
Perform standard concrete PH Testing. If the PH is greater
than 10, it must be neutralized, contact Ground Zero for
recommendations. Testing results and a diagram of testing
locations shall be submitted to Ground Zero Electrostatics,
Inc prior to installation of ESD Flooring If the results
exceed the limitations we specify.
2. Upon
receipt of rolls, check that colors correspond to those
ordered, that quantities are correct and dye lots are consistent.
Rolls of material should be stored upright. Insure that
all equipment and trades have completed their work and
removed their equipment and materials prior to installation.
3. Maintain
building temperature, flooring and adhesive at a minimum
of 68 degrees F for a Period of 72 hours prior to, during
and after installation of Ground Zero Electrostatics, Inc
PolyStat Flooring. PolyStat ESD Vinyl sheets must be relaxed
prior to installation. Remove factory wrappers from rolls,
unroll vinyl sheets (these may be smoothly placed on top
of each other for faster relaxation). Allow material to
flatten for a period of 72 hours in a warm to hot environment
prior to installation.
4. Remove
all debris, sweep or vacuum entire floor area. Subfloor
must be dry, clean and free from dust, paint, oil, grease,
curing agents, parting compounds, surface hardeners, sealers
solvents, old adhesives and any other extraneous materials.
Substrate must be smooth and flat with a maximum variation
of 1/8 & #8216; in 10 feet. Cracks and any irregular surfaces
must be patched and leveled using a Portland cement underlayment
with a liquid latex binder. Gypsum-based underlayment should
not be used. Excessive subfloor irregularities may telegraph
through the PolyStat ESD Vinyl and may be visible on the
surface of the finished installation.
5. Scrape
or power grind any cementious subfloor to remove any excessive
ridges or contaminants, fill all voids in concrete (including
expansion joints) sweep or vacuum prior to laying.
6. The
Architect may have provided a drawing showing the direction
in which the material should be laid. In this case lay
the sheet as directed. If the Architect has left this to
the discretion of the flooring installers, layout your
installation as you would for standard non ESD Vinyl paying
attention to where seams will fall and avoiding such occurrences
as seams in the middle of doorways. If large windows are
installed, minimize the effect of the joints by laying
towards the window.
7. Trowel
and Roller Method of Adhesive Transfer:
- It is essential
that the specified trowel be used! If the trowel notches
are too large too much adhesive will be applied. This
will result in excessive adhesive seepage at the seems
and also will cause the Vinyl to "float" and
shift. In addition excessive adhesive will make clean
up difficult. Excessive adhesive should be immediately
cleaned from Vinyl with warm water. Do not use Acetone.
If you delay in rolling the Vinyl because of excessive
seepage, adhesive will not be properly transferred to
the backing of the Vinyl causing both a loss in Conductivity
and lowered adhesion. If the notches are too small, too
little adhesive will be used resulting in lowered conductivity
and/or lowered adhesion. As this adhesive contains carbon
trowel wear will be noticeably increased. Worn trowels
should be immediately discarded when proper spread rate
becomes impaired.
Trowel Size:
Porous concrete; 1/16 X 1/16 U notched
Non-Porous substrates (double drop and use); 1/32 X 1/32 U notched
- PolyStat ESD
Flooring can be installed by using the double drop method
(recommended for non-pours substrates). Spread and trowel
adhesive, lay vinyl sheet into wet adhesive and roll
(see c), then fold vinyl sheet back and leave until adhesive
becomes slightly tacky to the touch. Once proper adhesive
tack takes place vinyl sheet should be accurately re-laid,
ensuring vinyl does not twist or develop trapped air
bubbles. Tack time will very depending on ambient humidity
conditions in your environment. PolyStat may also be
layed into wet adhesive on porous substrates. We recommend
bond strength testing to decide on the appropriate method
of adhesive usage prior to full scale installation.
- It is important
that the proper weight roller be used! The floor is rolled
to flatten the adhesive ridges left by the trowel and
to transfer a uniform amount of adhesive to the backing
of the PolyStat Vinyl Sheet Goods. Our GZ-C2000 conductive
adhesive will stay wet beneath the installed floor for
a extended period of time. Bond and tack strength will
increase as adhesive cures. As such PolyStat "bubbles" may
be removed for a period of up to 48 hours after flooring
install by re-rolling and / or weighting bubbles with
cinder block weights.
Roller Weight: 150 Pound
8. Heat
Welding: Allow floor to cure for a minimum of 48 hours
prior to heat welding seams. Heat weld in accordance with
standard high grade composition vinyl flooring practices.
Installers Checklist
- Conduct Calcium
Chloride moisture test, insure that the results do not
exceed 6.0 lbs per 1000 square feet in a 24 hour period.
- Test for pH
levels insure that the pH of concrete substrate does
not exceed10.
- Perform bond
strength test using standard installation parameters.
- Permanent HVAC
system must be turned on and set to a minimum of 68o
F for a minimum of 72 hours prior to, during and after
installation. With maximum environmental temperature
not to exceed 100o F.
- Climatize material
to installation area for a minimum of 24 hours prior
to installation.
- Use only Ground
Zero Electrostatics, Inc approved conductive adhesive.
- Use proper
trowel blades as listed above.
- Inspect material
visually prior to installation! Any material installed
with visual defects will not be considered legitimate
claim as it pertains to labor cost. Make sure that the
tiles are all from the same batch numbers as indicated
on the cartons.
- Do not allow
heavy equipment on the newly installed floor for a minimum
period of 72 hours. Normal foot traffic may be allowed
after a period of 24 hours in most environments.
Maintenance / Post Install Cleanup:
Post install cleaning can be accomplished with standard rotary buffing equipment,
semi abrasive pad and water. HOWEVER water nor buffing should not be utilized
for a period of 72 hours after installing floor. Maintenance is dependant on
the nature and intensity of traffic and the specific requirements of the end
user. To keep cost low, without compromising standards of hygiene and cleanliness,
Ground Zero Electrostatics, Inc recommends that a maintenance regime be specifically
tailored to your needs. Polishes or floor finishes that inhibit the floors
electrical performance must not be used. Remove abrasives by sweeping on a
regular basis. Damp mop with warm water and approved Ground Zero Electrostatics,
Inc Cleaning solution as needed. A clean floor insures consistent electrical
performance. PolyStat ESD Vinyl is initially supplied with a non-glare finish.
If your needs require a high shine, simply burnish the material with a high
speed floor buffing machine. Contact Ground Zero Electrostatics,
Inc for further recommendations. |
