Do not apply coating to bare concrete when there is potential for surface temperature to increase during application or initial cure.

The air temperature shall be between 60 degrees F (16 degrees C) and 100 degrees F (38 degrees C).

Surface temperatures must be between 60 degrees F (16 degrees C) and 100 degrees F (38 degrees C). Surface temperatures shall be at least 8 degrees F (3 degrees C) above the dew point and not falling during coating application and throughout initial cure.

No coating shall be applied when the relative humidity is above 85 percent or as specified in the Coating Manufacturer's product data sheet.

3.7 TILE AND TILE ADHESIVE REMOVAL

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 4,000 psi. Resulting surfaces shall appear clean and display the gray color of concrete.

3.8 JOINT MATERIAL REMOVAL, RE-SAW CUTTING, CRACK CHASING

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 1/8 inch when re-saw cutting. Chase concrete cracks identified for repair and open to a minimum depth of 1/2 inch below crack surface with smooth vertical walls.

3.9 GROUNDING

Install a grounding system, using copper tape, embedded #18 bare copper wire (embedded in cut channels), or other suitable method to ensure that each 1,000 square foot of coated surface area is directly connected to a facility grounding point. Install grounding points as required. Existing metal floor joints, equipment bases and steel columns or posts may potentially be used as grounding points if they have been electrically tested to verify continuity with an earth ground. Submit a detailed grounding system plan, including product mfg. requirements, connection

SECTION 09 67 23.15 Page 16 details, and drawings or sketches that illustrate the exact placement of the system and how connections will be made. The submittal shall include the product manufacturer's written concurrence with the grounding system plan. The coating system shall be applied in direct, uninterrupted, contact with the properly prepared grounding points. The connection of the grounding system to the ground connection points shall be performed by a licensed electrical engineer.

3.10 DEGREASING

On both coated and uncoated concrete, degrease entire floor by scrubbing using a solution of hot potable water, 120 degrees F to 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 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.

3.11 COATING SYSTEM REMOVAL

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.

3.12 SURFACE PREPARATION

Shot blast entire floor to produce a level of coarseness similar to ICRI 03732 CSP 3. Overlap each pass of shot blasting by 1/4 inches to 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 similar 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 similar 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 similar 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.

3.13 JOINT TREATMENT

Use the "Conventional Sealed Joint" as detailed in Figure 1 of SSPC-TU 2/NACE 6G197 to seal joints. Employ measures to reduce

SECTION 09 67 23.15 Page 17 contamination from equipment and foot traffic. Limit floor access to essential contractor personnel. Confirm joint surfaces are sufficiently clean.

3.13.1 Install Backer Rod

Install a continuous length of round, closed-cell polyethylene backer rod into each joint using a backer rod tool. For 1/2 inch, 3/8 inch, and 1/4 inch wide joints, place backer rod to a depth of 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 3/4 inch width, place backer to a depth of 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.

3.13.2 Sealant Application

Apply sealant directly into joints using a bulk-caulking gun. At room temperature, the resulting sealant application shall exhibit a concave recess between 1/8 inch to 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.

3.14 PRE-APPLICATION TESTING FOR CONTAMINATION

Spot check surfaces for oil/grease contamination using the water break test. At a rate of 5 tests per 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."

3.15 COATING APPLICATION

Coat prepared and approved surfaces before the occurrence of any contamination.

All surfaces shall comply with the specified level of cleanliness at the time of coating application.

Vacuum flooring space one additional time immediately prior to coating application and mark all joints.

Apply and cure all products in strict accordance with manufacturer's written instructions, using good practices and technique as required to achieve optimal results.

Only utilize methods and application equipment that are recommended by the Manufacturer in writing.

The application and handling characteristics of all products will vary. To obtain optimum performance, adequate written instructions from the manufacturer are essential and must be closely followed in conjunction with the requirements defined herein.

SECTION 09 67 23.15 Page 18

Solvents used for cleanup shall be as recommended on the product data sheet and must be a product provided by the Manufacturer unless alternate written recommendations are provided in writing by the product Manufacturer.

The first coat application to bare concrete surfaces shall only be applied after the concrete surface has reached its maximum daily temperature, which usually occurs in the early afternoon. Do not apply coatings to bare concrete surfaces when the temperature is expected to increase. This is to help prevent pin-holing caused by expansion of air in the porous concrete surface.

3.15.1 Moisture Reducing System (Priced as option)

Apply moisture reducing system to flooring space according to manufacturers instructions. Strict adherence to minimum thickness is required for successful coating performance.

3.15.2 Primer Application

Apply primer to flooring space at 7.0 mils to 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 7.0 mils DFT. If the prepared concrete resembles an ICRI 03732 CSP 5 surface, apply the primer at a maximum of

15.0 mils DFT. The previously applied sealant may be lightly coated.

3.15.3 Non-Skid Grit Broadcast

Broadcast non-skid grit at a rate of 1.5 pounds per 100 square feet into the first urethane top coat and backroll. Map floor into 600 square foot sections where 9.0 pounds of non-skid grit is pre-weighed, placed into clean buckets and used in its entirety per marked 600 square foot section.

3.15.4 Application of Topcoats

Apply two coats of urethane topcoat to the epoxy primer and broadcast non-skid grit directly into the first urethane topcoat.

3.15.4.1 First Topcoat

Apply a full coat of the urethane topcoat at a spreading rate from 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 600 square feet of floor surface. Sealant is to be lightly coated. Monitor and record a minimum of one WFT reading per 600 square feet of floor surface prior to broadcasting non-skid grit. When the correct WFT has been applied per 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".

3.15.4.2 Second Topcoat

Apply a second coat of the urethane topcoat at a spreading rate of 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 600 square feet of floor surface prior to broadcasting non-skid grit. When the correct WFT has been applied per 600 square feet of area, immediately and evenly broadcast non-skid grit directly into the second topcoat of urethane and backroll in

SECTION 09 67 23.15 Page 19 two directions. Test the adhesion of the thin film flooring system in accordance with the Article entitled "ADHESION TESTING."

3.15.4.3 Markings, Striping, and Labeling

Marking coatings must be compatible with the reflective coating systems or ESD/conductive systems. Traffic marking paints are not acceptable.

Markings coatings should be chemical-resistant, but moisture-cured urethane marking coatings generally are acceptable.

When the second topcoat is within its recoat window, apply the yellow and black striping at a minimum thickness of 3.0 to 4.0 mils DFT, completely hiding the top coat, in one coat. If insufficient hiding occurs, apply one additional coat. Use solvent resistant tape to protect the floor coating against stripe coat bleed. A thin clear coat of urethane may be required to prevent stripe coat bleed prior to the full application of the colored stripe coat. If the final coat has dried more than 48 hours, buff the area to be marked with No. 1 steel wool or No. 100 sandpaper to provide a good bond. Wipe areas clean before coating. Apply grounding rod markings using similar procedures.

3.15.4.4 Striping and Grounding Rod Markings

Replacement of striping, labeling, and marking is considered part of the flooring system and is not a separate cost item. Mark, map, measure, photograph, and detail all striping, labeling and markings as necessary to ensure replacement of each in their original location and position, with matching colors and sizing, and consistent with the requirements for each particular facility. Submit documentation and photos of striping, labeling, and marking locations prior to surface preparation activities.

Unless specified otherwise, grounding rod markings shall be according to UFC 3-575-01. Submit detailed striping and marking plan, including sketches of layout, marking sizes, marking products, and application details for Government approval.

3.15.4.5 Labeling

Replace existing aluminum caution placards with stenciling that match existing size, wording and color. See Government drawings for caution placard details.

3.16 CURING

Cure installed materials to display performance equal to manufacturer's product literature. Remove and reapply improperly cured material.

3.17 FIELD TESTS AND INSPECTION

3.17.1 Coating Inspector

Immediately report to the Government any deviation from the specified requirements.

Provide multiple inspectors if necessary to ensure adequate quality control coverage of all work being performed. Maintain a ratio of production workers to inspectors that is less than 12:1.

The Coating Inspector(s) shall be considered a QC Specialist. The Coating Inspector's primary responsibility shall be to assure compliance with

SECTION 09 67 23.15 Page 20 specified requirements. The Coating Inspector(s) shall be present full-time during all pre-preparation testing, surface preparation, paint application, initial cure of the paint, paint repair work, and project completion activities. The Coating Inspector(s) shall provide complete documentation of conditions and occurrences on the jobsite, facilitate timely reporting of any technical issues to Government Representative and be aware of conditions and occurrences that are potentially detrimental to the performance of the coating system. There will be no other duties required of the coating inspector.

3.17.2 Inspection

Document weather conditions, job site occurrences, and report conditions and occurrences potentially detrimental to the flooring system. 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.

3.17.2.1 Daily Inspection Report

Submit to the Contracting Officer the daily inspection reports completed each day when performing work under this Section. Use Appendix X1 "Inspection Checklist" of ASTM D6237 to monitor daily activity and to assist in preparing the daily inspection report. Note each non-compliant issue and each issue identified for rework. 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 12 hours of the report date.

3.17.2.2 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.

3.17.2.3 Inspection Equipment

3.17.3 Testing for Moisture

Test moisture vapor emission (MVE) levels after surface preparation and prior to application of any coatings, including Test Patch, in accordance with ASTM F1869. Each kit shall be applied directly to uncoated concrete for a continuous period of 60 to 72 hours. Testing shall be on prepared surfaces at least 96 hours after any wet processes (i.e; degreasing), and no more than 36 hours prior to initial coating application. Apply three

SECTION 09 67 23.15 Page 21

Moisture Vapor Emission (MVE) Test Kits in each test area, with at least one test area to be located in the center and one near each side of the floor slab. Test a minimum of five areas (3 test kits in each area) for floors up to 10,000 square feet. For floors larger than 10,000 square feet, test one area (3 kits) for every additional 2000 square feet of surface area. Report the concrete's rate of moisture vapor emission in each test area as the average of the three rates.

Acceptable Moisture Vapor Emission (MVE) is less than 3.5 pounds moisture per 24 hours, 1000 square feet, per ASTM F1869. If a concrete floor has a rate of Moisture Vapor Emission (MVE) that exceeds 3.5 pounds moisture per 24 hours, 1000 square feet (ASTM F1869), apply a Moisture Reducing System (MRS) prior to the application of the flooring system (BID OPTION). The MRS shall be compatible with the submitted flooring system and approved in writing by the manufacturer of the thin film flooring system. Apply the MRS to prepared concrete and reduce the rate of MVE to less than 3.0 pounds moisture per 24 hours per 1000 square feet before proceeding with the application of the floor coating system.

In addition to MVE testing, measure concrete moisture content (MC) using an electronic moisture meter, such as Tramex Concrete Encounter CME4, or Government approved…
