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

N/A

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 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

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

SECTION 09 67 23.15 Page 11 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.

3.7 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 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-caulking 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

SECTION 09 67 23.15 Page 12 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

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

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

SECTION 09 67 23.15 Page 13

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.
