4. PRODUCT HANDLING:

4.1 Storage of Materials: ACI 304.

5. ENVIRONMENTAL CONDITIONS:

5.1 Cold Weather: ACI 306R. Cold weather is defined as a period when for more than consecutive days the mean daily temperatures drop below 40 F (5 C). When temperatures above 50F (10 C) occur during more than half of any 24-hour period, the concrete should no longer be regarded as winter concrete. Heating of concrete should not exceed 90 F.

5.2 Inclement Weather: Protect freshly placed concrete against damage by infiltration of any adverse weather. When damage might occur, terminate placing against nearest construction joint bulkhead and cover at once with waterproof protection until concrete has set.

5.3 Sprayed-on Protective Coatings: Apply when air temperature is between 50 F (10 C) and 80 F (27 C), relative humidity below 80 percent. Do not apply when rain is forecast within 24 hours.

5.4 Hot weather: ACI 305. work plans must include preparation to limit the temperature affects on concrete. As the selected limiting temperatures, usually but not always between 75 F to 100 F (24C to 38 C) is approached and exceeded, it is likely that the unfavorable effects of high temperature will occur.

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 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

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.

3.3 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.

3.4 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.

3.5 SURFACE PREPARATION

Shot blast entire floor to produce a level of coarseness equal to ICRI 03732

SECTION 09 67 23.15 Page 6

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 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.

3.6 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.

3.6.1 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.

3.6.2 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 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.

3.7 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."

SECTION 09 67 23.15 Page 7

3.8 COATING APPLICATION

Vacuum flooring space one additional time prior to coating application.

3.8.1 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.

3.8.2 Non-Skid Grit Broadcast

Broadcast non-skid grit at a rate of 1.5 pounds per 100 square feet into the second 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.

3.8.3 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.

3.8.3.1 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.

3.8.3.2 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 two directions. Test the adhesion of the thin film flooring system in accordance with the Article entitled "ADHESION TESTING."

3.8.3.3 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 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.

SECTION 09 67 23.15 Page 8

3.9 CURING

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

3.10 FIELD TESTS AND INSPECTION

3.10.1 Coating Inspector

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.

3.10.2 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.

3.10.2.1 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. 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.

3.10.2.2 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.

3.10.2.3 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.

SECTION 09 67 23.15 Page 9

3.10.3 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 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 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 40 milsconcrete removed over 95 percent of each pull-off coupon, and/or adhesion more than 400 psi coating system's adhesion is acceptable. If the above requirements are not satisfied, then perform one adhesion test per 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.

3.11 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.
