flooring system with reflective urethane topcoats, slip resistance, and joint
work.
Edit this guide specification for project specific requirements by adding, deleting,
or revising text. For bracketed items, choose applicable items(s) or insert
appropriate information.
Remove information and requirements not required in respective project, whether
or not brackets are present.
Comments and suggestions on this guide specification are welcome and should
be directed to the technical proponent of the specification. A listing of technical
proponents, including their organization designation and telephone number, is
on the Internet.
Recommended changes to a UFGS should be submitted as a Criteria Change Request
(CCR).
NOTE: The thin film flooring system is appropriate for use in: aircraft maintenance
hangars, equipment maintenance shops, and all other industrial floors where
resistance to abrasion and fuel is required. Installation costs: $2.00 - $4.50
per 0.1 square meters square foot. Nominal thickness: 0.375 mm 15.0 mils. Can
be rejuvenated by replacing urethane topcoats, and non-skid, only. Approximate
service life: Urethane top coating with non-skid grit at three or more years.
The flooring system is neither conductive nor Electro-Static Dissipative (ESD),
however, either formulation is easily designed upon request. This specification
is not for use in overcoating existing sound floor coatings.
NOTE: Prior to the flooring systems installation, a concrete condition assessment
in accordance with the Naval Facilities Engineering Service Center's (NFESC)
Users Guide (UG)-2036-SHR is highly recommended. The condition assessment is
designed to identify problem floors and eliminate premature flooring failures
produced by: 1) coating concrete with low surface strength, 2) coating concrete
with high levels of surface contamination (oils, fuels, fats, waxes, etc.),
and 3) coating concrete with a high rate of Moisture Vapor Emission (MVE).
The thin film flooring system is suitable for application to: A) "smooth" concrete
surface texture, B) concrete with a rate of MVE no more than 169.0 micrograms
moisture per second, square meter3.0 pounds moisture per 24 hours, 1000 square
feet (ASTM F 1869), C) concrete with surface strength greater than 1.34 MPa
200 psi (ASTM D 4541), and D) concrete with fuel/oil contamination to a depth
no more than 6.25 mm 1/4 inch.

ICRI 03732, including replica standards ICRI 03732 CSP 1 through CSP 9, at the job site.
1.7 PATCH TEST DEMONSTRATION
NOTE: This is a very important part of the submittal process. While it is
unusual to require a test patch prior to the submitted coating system's approval,
this flooring system is unusual in that it is required to provide extended,
uninterrupted performance. A demonstration of contractor claims, especially
under conditions to be encountered in the specific project, is considered necessary.
If customer dislikes level of non-skid grit, adjustments to the specification
can be made. Grit coarser than #60 aluminum oxide is not recommended. On architectural
floors, non-skid grit broadcast rates can range from none to approximately half
the specified level.
Prior to the submitted flooring system's approval, apply the complete coating system to a 3 meter by 3 meter
10 foot by 10 foot square section of concrete as prepared in accordance with Part 3 "EXECUTION." Within this
area, perform three adhesion tests as described in the Article entitled "ADHESION TESTING." If adhesion testing
produces cohesive failures within the concrete, no less than 1 mm 40 mils concrete removed over 95 percent of
each pull-off coupon, and/or adhesion more than 2.75 MPa 400 psi, patch test adhesion is acceptable. If concrete
surface preparation was insufficient, apply an additional coating system patch to properly prepared concrete
followed by the above adhesion testing. If adhesion results are unacceptable for both the topcoats and the primer,
submit a new coating system manufactured by a different coating vendor. Apply a patch of the new coating system
and subject patch to the above requirements for adhesion prior to approval. If customer dislikes non-skid grit
application, adjustments to the specifications can be made. Grit coarser than #60 aluminum oxide is not recommended.
PART 2 PRODUCTS

PART 3 EXECUTION
3.1 COATING SAMPLE COLLECTION
The Contracting Officer and QC Manager shall witness all material sampling. Notify the Contracting Officer a
minimum of three days in advance of sampling. Obtain liquid samples of each component of primer and topcoat
by random selection from sealed containers and in accordance with ASTM D 3925. Samples may be either individual
cans of liquid material or 1.0 liter 1.0 quart quantities of properly mixed, extracted, and sealed liquid material.
Identify samples by designated name, specification number, batch number, project contract number, sample date,
intended use, and quantity involved. When the applied coating system has met the requirements defined in the
Article entitled "ADHESION TESTING," return coating to the installation contractor for proper disposal.
[3.2 TILE AND TILE ADHESIVE REMOVAL
NOTE: Delete "Tile and Tile Adhesive Removal" if concrete is not tiled.
Remove 100 percent of tile employing one or more of the following techniques: chipping, scraping, sanding, scarification,
high-pressure water, and various hand tools. Remove 100 percent of the tile adhesive using solvents and power
scrubbing. Remove residual contamination using hot potable water under a minimum of 27.6 MPa 4,000 psi. Resulting
surfaces shall appear clean and display the gray color of concrete.
]3.3 JOINT MATERIAL REMOVAL, RE-SAW CUTTING, CRACK CHASING
NOTE: Hairline cracks having no more than 3.2 mm 1/8 inch width are typically
not repaired. However, cracks greater than 3.2 mm 1/8 inch width can be chased
to a minimum depth of 12.5 mm 1/2 inch and sealed using the procedures and materials
specified for joints. Cracks more than 18.75 mm 3/4 inch width can be repaired
using either epoxy mortar and/or epoxy concrete. Sealed cracks will assist
in protecting the subbase against chemical migration.
Remove 100 percent of the existing material in all joints including material bonded to joint walls and base.
Rigid material may require the use of saw cutting equipment to remove. Joints may be widened up to 3.2 mm 1/8
inch when re-saw cutting. Chase concrete cracks identified for repair and open to a minimum depth of 12.5 mm
1/2 inch below crack surface with smooth vertical walls.
3.4 DEGREASING
On both coated and uncoated concrete, degrease entire floor by scrubbing using a solution of hot potable water,
49 degrees C 120 degrees F to 77 degrees C 170 degrees F, and a concentrated water-based alkaline degreaser.
Perform two complete degreasing cycles on the entire floor surface. Allow solution to soak into surfaces prior
to scrubbing and remove using hot potable water under a minimum of 27.6 MPa 4,000 psi. Rinsing is complete when
the rinse water appears clear. If the industrial detergent is not biodegradable, collect all rinse water and
dispose as hazardous waste. Squeegees and shop vacuums may be used to collect pooling rinse water. Fans may
be used to aid drying of floor surfaces.
[3.5 COATING SYSTEM REMOVAL
NOTE: Delete "Coating System Removal" if concrete is uncoated.
Remove 100 percent of the existing coating system employing one or more of the following techniques: shot blasting,
chipping, scraping, sanding, scarification, high pressure water blasting, and various hand tools. The use of
impact tools such as scabblers may be used to remove unsound epoxy mortar flooring systems. In general, a coating
system cannot be completely removed by shot blasting and, to attain 100 percent coating removal, and requires
a combination of the above techniques.
]3.6 SURFACE PREPARATION
Shot blast entire floor to produce a level of coarseness equal to ICRI 03732 CSP 3. Overlap each pass of shot
blasting by 6.25 mm 1/4 inches to 12.5 mm 1/2 inches. Add new shot to shot blasting equipment prior to blasting.
Prepare surfaces inaccessible to shot blasting, base of perimeter walls and under secured equipment, using diamond
disk grinding and/or light scarification to produce a level of coarseness equal to ICRI 03732 CSP 2 and/or ICRI 03732
CSP 4, respectively. Resulting surfaces shall appear clean and contain the appropriate level of surface coarseness.
If the resulting level of cleanliness cannot be determined, place numerous drops of water on surfaces that appear
contaminated. If the water drops soak into concrete, the surfaces are free of hydrocarbon contamination (oils,
grease, skydrol). If the water drops bead up and do not flatten out, surfaces require additional degreasing as
detailed in the Article entitled "DEGREASING." Shot blasting coarse concrete and/or broom finished concrete
can produce a level of coarseness equal to ICRI 03732CSP 5: employ a best effort attempt to minimize over shot
blasting of coarse concrete. If coarse concrete is encountered, shot blasting to a level of coarseness equal
to ICRI 03732 CSP 5 is acceptable: however, extremely coarse concrete can require resurfacing prior to the flooring
system's installation. Sweep, vacuum, and run a high powered magnet over all surfaces to be coated, including
joints.
NOTE: At this point in the installation sequence, minor spalls and surface deterioration
to depths less than 75 mm 3 inches can be repaired. Use epoxy mortar for repairs
to depths no more than 50 mm 2 inches. Use epoxy concrete for repairs to depths
from 25 mm to 75 mm 1 inch to 3 inches. Finish repairs to depths greater than
25 mm 1 inch with a rectangular geometry with saw cut edges. Repairs shall
be finished to resemble surrounding concrete using a stainless steel trowel.
Include Section 03 01 30.71 CONCRETE REHABILITATION if concrete repairs of this
nature are required.
3.7 JOINT TREATMENT
Use the "Conventional Sealed Joint" as detailed in Figure 1 of SSPC-TU 2 to seal joints. Employ measures to
reduce contamination from equipment and foot traffic. Limit floor access to essential contractor personnel.
Confirm joint surfaces are sufficiently clean.
3.7.1 Install Backer Rod
Install a continuous length of round, closed-cell polyethylene backer rod into each joint using a backer rod
tool. For 12.5 mm 1/2 inch, 9.4 mm 3/8 inch, and 6.25 mm 1/4 inch wide joints, place backer rod to a depth of
9.4 mm 3/8 inch (depth equals the distance from the concrete's surface to the highest point on the backer rod).
For joints greater than or equal to 18.75 mm 3/4 inch width, place backer to a depth of 15.6 mm 5/8 inch below
the concrete's surface. Fit backer rod tight between joint walls (30 percent compression). Remove and reinstall
all backer rod that is installed using either the incorrect size (loose fit) or at the incorrect depth. Following
backer rod installation, apply painter's tape to surfaces adjacent joints to protect from sealant.
3.7.2 Sealant Application
Apply sealant directly into joints using a bulk-calking gun. At room temperature, the resulting sealant application
shall exhibit a concave recess between 3.2 mm 1/8 inch to 1.6 mm 1/16 inch below the concrete's surface. Remove
and reapply cured sealant remaining either flush or greater. Following sealant application, remove painter's
tape and sealant drips on concrete surfaces. Cure sealant a minimum of 24 hours, prior to the application of
coatings.
3.8 PRE-APPLICATION TESTING FOR CONTAMINATION
Spot check surfaces for oil/grease contamination using the water break test. At a rate of 5 tests per 95 square
meters 1000 square feet, place one to two drops of water onto surfaces and observe for beading. Test all other
surfaces that show visible signs of potential contamination. Apply additional degreasing techniques to surfaces
displaying water beading in accordance with the Article entitled "DEGREASING."
3.9 COATING APPLICATION
NOTE: Use epoxy primer the same color, either white or ultra-light gray, as
the selected topcoats. Ultra-light gray is preferred to white.
Vacuum flooring space one additional time prior to coating application.
3.9.1 Primer Application
Apply primer to flooring space at 175 microns 7.0 mils to 375 microns 15.0 mils Dry Film Thickness (DFT). If
the prepared concrete resembles an ICRI 03732 CSP 3 surface, apply the primer at a minimum of 175 microns 7.0
mils DFT. If the prepared concrete resembles an ICRI 03732 CSP 5 surface, apply the primer at a maximum of 375
microns 15.0 mils DFT. The previously applied sealant may be lightly coated.
3.9.2 Non-Skid Grit Broadcast
NOTE: Aircraft hangars servicing light aircraft with weight less that 18,140
kg 40,000 pounds may require a higher loading of non-skid grit. The additional
grit will assist in towing aircraft under wet conditions; however, the additional
grit will decrease coating aesthetics. Up to 450 grams 1 pound per 93 square
meters 100 square feet of additional non-skid grit can be required
On either warehouse or architectural floors, considerably less non-skid grit
may be appropriate. Broadcast rates can range from none to less than 450 grams
1.0 pound per 93 square meters 1000 square feet.
Broadcast non-skid grit at a rate of 680 grams 1.5 pounds per 9.3 square meters 100 square feet into the second
urethane top coat and backroll. Map floor into 55.8 square meter 600 square foot sections where 4080 grams 9.0
pounds of non-skid grit is pre-weighed, placed into clean buckets and used in its entirety per marked 55.8 square
meter 600 square foot section.
3.9.3 Application of Topcoats
Apply two coats of urethane topcoat to the epoxy primer and broadcast white aluminum oxide non-skid grit directly
into the second urethane topcoat.
3.9.3.1 First Topcoat
Apply a full coat of the urethane topcoat at a spreading rate from 62.5 to 80 microns 2.5 to 3.2 mils Dry Film
Thickness (DFT). Stripe coat perimeter edges and around equipment footings. Monitor and record a minimum of
one Wet Film Thickness (WFT) reading per 55.8 square meter 600 square feet of floor surface. Sealant is to be
lightly coated.
3.9.3.2 Second Topcoat
Apply a second coat of the urethane topcoat at a spreading rate of 62.5 to 80 microns 2.5 to 3.2 mils DFT. Stripe
coat perimeter edges and around equipment footings. Monitor and record a minimum of one WFT reading per 55.8
square meters 600 square feet of floor surface prior to broadcasting non-skid grit. When the correct WFT has
been applied per 55.8 square meters 600 square feet of area, immediately and evenly broadcast non-skid grit directly
into the second topcoat of urethane and backroll in two directions. Test the adhesion of the thin film flooring
system in accordance with the Article entitled "ADHESION TESTING."
3.9.3.3 Walkway Stripe and Grounding Rod Markings
Place the walkway stripe and grounding rod markings according to Government drawings, if applicable. When the
second topcoat is within its recoat window, apply a walkway stripe of the red/orange urethane topcoat at 75 microns
3.0 mils DFT, completely hiding the top coat, in one coat. If insufficient hiding occurs, apply one additional
coat of the walkway stripe. Lightly broadcast non-skid grit into the wet walkway stripe. Use solvent resistant
tape to protect the floor coating against stripe coat bleed. A thin clear coat of either epoxy or urethane may
be required to prevent stripe coat bleed prior to the full application of the colored stripe coat. Apply grounding
rod markings using similar procedures, urethane top coat, and colors and size according to Government drawings.
3.10 CURING
Cure installed materials to display performance equal to manufacturer's product literature. Remove and reapply
improperly cured material.
3.11 FIELD TESTS AND INSPECTION
3.11.1 Coating Inspector
NOTE: Insert directly into Section 01 45 02 NAVFAC
QUALITY CONTROL requirement for NACE Coating Inspector. See Appendix A for
instructions on modifying Section 01 45 02 NAVFAC
QUALITY CONTROL. The NACE Coating Inspector will act as QC Specialist.
Consider the Coating Inspector as a QC Specialist, who works for the QC Manager, and be qualified in accordance
with Section 01 45 02 NAVFAC
QUALITY CONTROL. The Coating Inspector will be present during all field tests, surface preparation, flooring
application, initial cure of the flooring system, and during all flooring repair work. The Coating Inspector
will provide all tools/equipment necessary to perform field tests and inspection. The Coating Inspector will
be responsible for field tests and specified level of inspection.
3.11.2 Inspection
Document weather conditions, job site occurrences, and report conditions and occurrences potentially detrimental
to the flooring system. The listed inspection requirements are in addition to the QC inspection and reporting
requirements defined in Section 01 45 02NAVFAC QUALITY CONTROL.
Prepare a project reference sheet outlining all requirements, tests, test methods, and evaluation criteria, and
hold regular meetings with contractor personnel, including shot blasting operators and applicators, to review
requirements/evaluation criteria for upcoming work prior to execution. At the start of coating operations and
every 1.0 hour following until daily work is complete, record air temperature, substrate temperature, and relative
humidity. Following the application of each coat, inspect surfaces for improperly cured material, blisters,
inadequate and/or excessive coating thickness, and other defects. Document each inspection, test, non-compliant
area, and location of each non-compliant area. List method of evaluation, evaluation criteria, areas requiring
rework, and all other pertinent observations.
3.11.2.1 Daily Inspection Report
Submit to the Contracting Officer one copy of the daily inspection report completed each day when performing
work under this Section. Use Appendix X1 "Inspection Checklist" of ASTM D 6237 to monitor daily activity and
to assist in preparing the daily inspection report. Note each non-compliant issue and each issue identified
for rework in accordance with the QC documentation procedures of Section 01 45 02 NAVFAC
QUALITY CONTROL. Use of forms containing entry blocks for all required data is encouraged. The data shall be
legible and presented in a professional format. Submit report within 24 hours of the report date.
3.11.2.2 Inspection Logbook
Record all daily activity related to this section in the Inspection Logbook, including the daily inspection reports,
as well as all other pertinent observations and information. Use hard or spiral bound book with consecutively
numbered pages. Prior to final payment, submit original Inspection Logbook to the Contracting Officer upon completion
of project.
3.11.2.3 Inspection Equipment
Use equipment in good condition, operational within its design range, and calibrated as required by the specified
standard for use with each device.
3.11.3 Adhesion Testing
Perform a minimum of three adhesion tests in accordance with ASTM D 4541 to the thin film flooring system. Select
three random flooring locations spaced a minimum of 6 meters 20 feet between each location. Prior to attaching
pull-off coupons, lightly sand flooring surface and attach pull-off coupons containing a grit-blasted anchor
profile. Adhere directly to the center of each sanded surface a 18.75 mm 3/4 inch diameter pull-off coupon.
When pull-off coupon adhesive has sufficiently cured, score circumference of each pull-off coupon to concrete
substrate. Test adhesion and evaluate results. If testing produces cohesive failures within the concrete, no
less than 1 mm 40 mils concrete removed over 95 percent of each pull-off coupon, and/or adhesion more than 2.75
MPa 400 psi coating system's adhesion is acceptable. If the above requirements are not satisfied, then perform
one adhesion test per 9.3 square meters 100 square feet using the above procedures. Perform two additional tests
per non-compliant area to confirm results. Remove to sound material and rework all areas unable to meet adhesion
requirements. Repair each adhesion test using a combination of primer, sand-filled epoxy mortar (for deep cohesive
failures, if applicable), and two urethane topcoats. Make repairs flush with adjacent coatings and display an
equivalent appearance.
3.12 FINAL CLEANUP
Following completion of the work, remove debris, equipment,and materials from the site. Remove temporary connections
to Government or contractor furnished water and electrical services. Restore existing facilities in and around
the work areas to their original condition.
