Static Dissipative Floor Finish
Application Instructions
Made in the
United States of America
the enhanced floor tile limits charge generation, for
example, due to a person walking across the floor.
Generally accepted industrial stripping and floor finish
application procedures are to be followed as outlined
on pages 2 and 3 in this technical bulletin. Note: to
avoid contamination finish mop and bucket should be
dedicated to Statguard
®
Floor Finish use only.
NOTE:
Statguard
®
Static Dissipative Floor Care products
do not have a set life span. The chemicals are not known to
degrade over time when stored at the proper temperature
conditions as stated in the Safety Data Sheet. We also
recommend that these products be stored in their original
containers and be sealed when not in use.
Figure 1. Statguard

Static Dissipative Floor Finish
When Statguard
®
Floor Finish is fully cured, the floor
finish does have white water resistance (a standard
industry test of standing water) however water if left
puddled on the surface will penetrate the surface like
other floor finishes and may turn white or powder.
GROUNDING
Conventional grounding practices like electrically
connecting Statguard
®
Dissipative Floor Finish to ground
is only required for applications of static dissipative floor
finish that are less than 50 square feet. For applications
that are greater than 50 square feet, the capacitance of
Statguard
®
Floor Finish is MANY, MANY times greater
than the capacitance of the human body model. The
difference in capacitance is so great that the Statguard
®
treated floor acts as a theoretical reservoir or natural
ground. The capacitance and surface resistance of
the Statguard
®
treated floor will decay a 5000V charge
to zero in .05 sec. per FTMS 101B, Method 4046.
Statguard
®
has substantially less than the maximum
static decay time of 0.1 seconds. Per ESD Handbook
ESD TR20.20 section 5.3.4.2 “Floor finishes and topical
antistats, function by two separate mechanisms. First
they reduce the surface’s tendency to generate a static
charge. Second, they provide a path for the dissipation
of charge. The charge may dissipate over the surface of
the finish or it may dissipate to ground if the floor finish
is grounded.”
To remove charge from personnel, ESD footwear is to
be used in conjunction with ESD flooring. ESD footwear
should be worn on both feet.
Description
Statguard
®
Static Dissipative Floor Finish is a cross
linked polymer used to convert hard non-ESD floors to
ESD protective flooring and for use in protecting and
enhancing ESD permanent flooring (vinyl, VCT, rubber
and other flooring types*). It creates a dissipative (1
x 10
6
to < 1 x 10
10
ohms per ANSI/ESD STM7.1 and
ESD TR53) and Low Tribocharging (<100 volts per
ANSI/ESD STM97.2) coating that meets or exceeds
ANSI/ESD S20.20 minimum requirements for use as a
primary grounding method and for charge generation
of the footwear/flooring system. Statguard
®
Static
Dissipative Floor Finish is 3-coat, 18% solids system
(Approx 2000 sq ft/gallon) that reduces dry time
and labor needed for initial application and on-going
maintenance.
*Testing a small area for compatibility if Statguard
®
Static Dissipative Floor Finish has not been used before
is recommended.
SAFE WALKING SURFACE
UL Classified for slip resistance only.
Underwriters
Laboratory has evaluated Statguard
®
Static Dissipative
Floor Finish to their slip resistance standards to ensure
employee safety and to mitigate user’s liability exposure
General Guidelines
Statguard
®
Floor Finish eliminates triboelectric
generated charges above 100V before costly damage
can occur from personnel who approach static sensitive
parts and products. Statguard
®
also drains static
charges from personnel who forget to reattach their
wrist straps minimizing the damage that could occur
from handling. Even when using conductive tiles, a
substantial triboelectric charge may be generated. When
Statguard
®
Floor Finish is applied over conductive tiles,

No Sealer Application:
Sealing is recommended for
increasing coverage and correcting problem concrete
surfaces that are not dry or free from grease, oil, etc.
If the subfloor surface is dry, level, and free from
dirt, grease, oil, paint, sealer, old adhesives, and
other foreign materials it may be suitable to applying
Statguard
®
finish directly onto the concrete.
COVERAGE
Statguard
®
Floor Finish covers approximately 2000
square feet per gallon per coat on smooth surfaces.
Coverage is less on coarse or textured surfaces. With
18% solids, Statguard
®
Floor Finish is easier to apply
with significantly better productivity than competing
brands.
Figure 2. ESD footwear should be used on ESD flooring
CONCRETE
Two measures are used to determine a good concrete
surface for Statguard
®
Floor Finish:
1. The surface should be cleaned of all contaminants.
2. The surface should be dry or sealed.
SURFACE
Surface to be finished should be clean, dry, and smooth.
Heavy dirt or grease build up should be removed with
a stripper or degreaser. DO NOT use Statguard
®
on
surfaces colder than 45° F. Statguard
®
Dissipative Floor
Finish contains zinc.
SEALING
Surface preparation is absolutely critical for porous
materials such as concrete. Proper preparation
simplifies application, increases durability, and is
essential for proper adhesion of the coating to the
substrate. Industrial grade polyurethane, vinyl, or
acrylic base sealers are recommended to seal high
porosity floors before applying the Statguard
®
Floor
Finish. Enamel can be used for bare wood, and enamel
undercoat with rust inhibitor for metal.
New concrete should cure for 60 days before sealing.
Not all concrete surfaces are created equal. They vary
widely in physical and chemical qualities due to the
way the concrete was originally formulated, poured or
finished.
Concrete surfaces are very porous and should be
properly sealed prior to the application of Statguard
®
Floor Finish. There are several methods to prepare
problem concrete. Each method depends on the
condition of the concrete. Cleaning methods range from:
sweeping, vacuuming, wire brush, air-blasting, water
jet, steam cleaning, or stripping. Adhesion properties
for the concrete sealer can be increased by profiling
or roughing surface through acid etching, rotary drum
sanding, scarifying, or mechanically scratching the
surface. The concrete sealer will reduce the porosity of
the concrete and provide a smooth and level surface for
the finish. The sealer also provides a barrier to prevent
any water migrating up through the concrete.
DRY TIME
It is recommended that Statguard
®
be allowed to dry at
room temperature in excess of 70°F for 1 hour or until
dry for each coat. At high relative humidity levels, a
longer drying time per coat may be necessary. Do not
use force air drying. After the last coat, wait 6 hours
before any light traffic, 12 hours before regular traffic, 72
hours before any wet maintenance, buffing, burnishing,
and heavy equipment and floor truck traffic.
SECURELY CLOSE CONTAINER AFTER EACH USE.
Optional Base Coat
Statguard
®
Conductive Epoxy or Acrylic Latex Paint
can be used as a base coat to enhance the electrical
properties where more conductive resistance is needed.
Statguard
®
Dissipative Floor Finish will seal out dirt,
debris and protect the conductive surface allowing for
ease of maintenance and enhanced shine. Statguard
®
Dissipative Floor Finish is a polymer base floor finish/
sealer that can be used as a top coat on the Conductive
Epoxy or Latex Paint. Two coats are recommended,
three coats will enhance electrical properties, durability
and reduce frequency of maintenance. Look online at
DescoIndustries.com
for Technical Bulletin
TB-7039
for
more information on Statguard
®
Conductive Epoxy or
Acrylic Latex Paint.
Floor Preparation - Stripping
Always use in a well ventilated area. Stripping the
floor is recommended for first time application of any
finish. New tiles are supplied with a protective factory
finish that protects during installation but should be
stripped away prior to any floor finish application.
Properly maintained floors should be stripped two to
four times annually, depending on traffic and buildup
of contaminated finish. Statguard
®
Floor Stripper is
recommended.
Equipment needed:
• Push broom
• Single pad 175 rpm swing floor machine (with a
black or brown stripping pad)
• Mops (do not use the same mop for stripper and for
floor finish)

Floor Stripper
Wet vacuum
either a pH measuring instrument or a piece of pH
indicating litmus paper. A safe pH will be 7.0 (neutral).
Statguard
®
Floor Finish Application
It is recommended that you apply two coats of
Statguard
®
Floor Finish. After stripping the factory finish,
new tile will have an initial high porosity and will require
three coats on first application. For known high traffic
applications, three coats are recommended for extended
life.
• If Statguard
®
freezes, allow it to thaw to 70° F and
mix completely before application.
1. Sweep away all loose dirt and trash.
2. Mix Statguard
®
Floor Stripper 3:1 three (3) parts
WARM water to one (1) part stripper.
3. Apply stripper liberally to around 200 square foot
area in need of stripping. Using a cotton string mop,
uniformly distribute the solution. Let the solution
stand for 5-15 minutes. Do not let it dry.
Figure 3. Stripping the floor
4. Scrub the floor with the floor machine at 175 rpm
(using a stripping pad soaked in stripping solution).
Work methodically, with at least two passes over
each area of the floor.
5. After scrubbing, pick up the solution with a wet vac
or mop.
6. Flood rinse the floor with clean, clear water.
Note:
Using Statguard
®
Floor Neutralizer can reduce the
number of rinse steps needed to get the floor to pH level
7.0 (neutral).
7. Pick up the rinse water with a wet vac or mop.
8. Repeat step 5 and 6. Entire floor should be rinsed
twice.
9. Damp mop the floor at least twice with clean mop
and clean water (change rinse water frequently to
ensure that all stripper solution residue is removed),
and let dry.
10. Visually inspect floor to be sure all stripper and old
polish (shiny spots) have been removed and test pH
level.
It is recommended to test the stripped surfaces after
the second rinse to ensure that high pH residues
are rinsed away. Some high pH strippers will leave a
residue behind even after several rinses. A high pH
can negatively affect the floor finish curing time as well
as other properties of the finish. To test for high pH
residue, test either the rinse water or the floor using
Figure 4. Applying floor finish
Figure 5. Applying floor finish with Flat Mop (optional).
FLAT MOP PROGRAM (OPTIONAL)
1. Flat mop can come with a refillable dispenser, that
allows for easier determination of proper amount of
Floor Finish / sq ft. For example, if the floor finish
application rate is 1 gallon / 2000 sq ft, a 32 oz
dispenser holds 500 sq ft of finish.
2. Flat mopping systems reduce workers fatigue as
they are lighter in weight. Roughly three pounds
when wet vs the traditional cotton loop mops which
can weigh eight to ten pounds when wet.
3. The Flat mop with dispenser is faster, as one does
NOT need to constantly “dip the mop and squeeze
out excess”.

4. The flat mop doesn’t hold as much residual finish
as a string mop, so the application of the proper
amount of Floor Finish, is more precise.
Equipment needed:
• Clean rayon (or cotton blend) mop, dedicated to
Statguard
®
Floor Finish use only
• Bucket dedicated to Statguard
®
Floor Finish use
only.
• Flat mop (Optional)
1. Pour Statguard
®
Floor Finish into a clean and
dedicated mop bucket and apply with a clean rayon
(or cotton blend) mop using a figure 8 motion.
2. Let the first coat dry (at least 60 minutes), then
apply a second coat. Do not use force air drying.
3. Let second coat dry for (at least 60 minutes) to
yield a bright gloss. Repeat application to attain
higher gloss and higher conductivity (two coats
will provide acceptable dissipative resistance on
most floors). Keep traffic from the floor for at least
six hours after the last coat is applied. See dry
time recommendations on page 2 in this technical
bulletin.
4. One or preferably two additional coats of floor finish
should be applied if the floor is to be maintained by
dry burnishing or spray buffing.
5. Maintain the polish following the Dust Mop, Damp
Mop, Floor Cleaner, Dry Burnish, or Spray Buff
maintenance procedure below.
FLOOR CLEANER PROGRAM
Statguard
®
Floor Cleaner will clean surface stains
and heel marks. As a cleaner it will reduce the gloss
of the floor. Do not re-apply Statguard
®
finish after
using Statguard
®
Floor Cleaner, see Mop and Recoat
program.
Heavy-Moderate Traffic:
Clean once a week, or as dictated by floor appearance.
Low Traffic Floors:
Clean floors as dictated by floor appearance.
1. Dust mop with untreated mop.
2. Dilute Statguard
®
Dissipative Floor Cleaner 10 parts
clean water to 1 part Floor Cleaner. For example,
use five (5) gallons of clean water to two (2) quarts
of floor cleaner.
3. Damp mop floor with cleaner solution and let
dry thoroughly. The mop and bucket should be
dedicated to Statguard
®
use only.
DRY BURNISH PROGRAM
Heavy-Moderate Traffic:
A dry burnish program will increase gloss and remove
surface imperfections.
Dry burnish once a week or as dictated by floor
appearance.
Low Traffic Floors:
Dry burnish as dictated by floor appearance.
1. Dust mop with an untreated mop.
2. Dry burnish at 1000-2000 rpm.
3. After dry burnish, dry mop the area with an
untreated dry mop if necessary.
SPRAY BUFF PROGRAM
A spray buff program will repair scratches, marks, and
other imperfections as well as gloss.
Heavy-Moderate Traffic:
Spray buff once a week or as dictated by appearance.
Low Traffic Floors:
Spray buff as dictated by floor appearance.
Equipment needed:
• Untreated dust mop
• Spray bottle
• 175-1500 rpm buffing machine with appropriate pad
Statguard

Maintenance
DUST MOP PROGRAM
1. Keep the floor surface clean. Use an untreated dust
mop or push broom nightly or as needed to remove
accumulated dirt and insulative contaminant.
DAMP MOP PROGRAM
1. Keep the floor surface clean. Use an untreated dust
mop or push broom nightly or as needed to remove
accumulated dirt and insulative contaminant.
2. To damp mop, use a 1 to 3 dilution of Statguard
®
Floor Finish in water (1 part Statguard
®
to 3 parts
water). Let dry thoroughly. The mop and bucket
should be dedicated to Statguard
®
use only.
MOP and RECOAT PROGRAM
To replenish solids that are worn away over time, a mop
and recoat can be done after cleaning the surface. This
can improve gloss and snap back electrical properties.
1. Follow the Damp Mop Program to clean the surface
above (do not use the floor cleaner)
2. Pour Statguard
®
Floor Finish (undiluted) into a clean
and dedicated mop bucket and apply a medium coat
with a clean rayon (or cotton blend) mop using a
figure 8 motion.
3. Let the coat dry (at least 60 minutes), then apply
a second coat if needed. Do not use forced air
drying.

Testing
In order to confirm the performance of Statguard
®
Dissipative Floor Finish the surface resistance and
charge generation of the flooring/footwear system
should be checked periodically. Testing either point
to point resistance (Rtt), resistance to ground (Rtg)
and charge generation per ESD TR53 and S20.20 will
indicate if the floor finish needs surface maintenance.
High floor traffic areas will need more frequent
maintenance than low traffic areas. We recommend
using the
Desco Digital Surface Resistance Meter
for measuring the surface resistance of the floor and
the
Kasuga Body Potential Meter
for measuring an
operator's charge generation.
