2. Traction Grit: To improve traction in slip hazard areas, use any of the following, depending upon the end user’s needs for slip resistance and ease of cleaning;

1. Tennant 291 Grit (60 mesh) – white aluminum oxide.

See 291 Grit Product Bulletin.

2. H&C® SharkGrip Slip Resistant Additive. See H&C®

SharkGrip Product Bulletin.

3. #8 - #10 Glass Beads

1. 6 C. PART 3 - EXECUTION

3.01 Examination

A. Examine concrete surface to receive floor coating system. Notify the Architect if surface is not acceptable. Do not begin surface preparation or application until unacceptable conditions have been corrected.

B. Allow concrete substrate to cure a minimum of 30 days.

C. CHECK THE TEMPERATURE AND HUMIDITY: Floor temperature and materials should be between 65°F (18°C) and 90°F (32°C). Humidity must be less than 80%. DO NOT coat unless floor temperature is more than five degrees over the dew point.

D. CHECK FOR MOISTURE: Concrete must be dry before application of this floor coating material. Concrete moisture testing must occur. Calcium chloride testing or in-situ relative humidity testing is recommended. Readings must be below 3 pounds per 1,000 square feet over a 24-hour period on the calcium chloride test or below 70% relative internal concrete humidity. Test methods can be purchased at www.astm.org, see ASTM F1869 or F2170, respectively or follow instructions from the suppliers of these tests.

NOTE: Although testing is critical, it is not a guarantee against future problems. This is especially true if there is no vapor barrier or the vapor barrier is not functioning properly and/or you suspect you may have concrete contamination from oils, chemical spills or excessive salts.

3.02 Preparation

A. Prepare surface in accordance with manufacturer's instructions.

1. Cleaning: Scrub with Tennant detergent and rinse with clean water to remove surface dirt, grease and oil.

2. Remove urethane coating to achieve a mechanical bond with underlying epoxy with one of the following methods:

1. Grind.

2. Sand with 80 grit sanding discs.

3. Vacuum residual dust, wipe clean with micro-fiber cloths treated with Isopropyl

Alcohol to remove remaining dust, multiple passes may be required.

3.03 Application

A. Apply floor coating system in accordance with manufacturer's instructions.

1. Assemble squeegees and rollers; clean rollers to remove residual lint.

2. Coating: Eco-CEP™ -- Colored Epoxy Primer.

1. Mix components together.

2. Mix only enough material which can be applied within 25 minutes.

3. Apply Eco-CEP™ at the rate of 53-160 ft2/gal.

4. Allow coating to cure 16 hours at 75 degrees F (24 degrees C) and 50% relative humidity.

3. Coating: Eco-HPS 100 - 100 g/L, VOC-Compliant, Gloss Urethane Topcoat.

1. NOTE: Epoxy must be thoroughly sanded and cleaned prior to application of Eco-HPS 100.

2. Open and mix only enough material which can be applied in a 2-hour period.

3. If installing using H&C® SharkGrip, mix into urethane until fully blended.

4. Apply Eco-HPS 100 at the rate of 500 ft2/gal. (12.3 m2/L).

5. Broadcast 291 Grit or Glass Beads and back-roll into urethane coating.

6. Allow coating to dry 24 hours at 75°F (24°C) and 50% relative humidity.
