4 PART 1 GENERAL 1.01 SECTION INCLUDES SECTION A. Surface treatments for concrete floors and slabs. B. Application of water soluble. Inorganic hardening, sealing and dustproofing product for treatment of uncovered concrete floor surfaces RELATED REQUIREMENTS A. Section Maintenance of Concrete 1.03 SUBMITTALS A. See Section Administrative Requirements, for submittal procedures. B. Product Data: Manufacturer's published data on each finishing product, including information on compatibility of different products and limitations. C. Maintenance Data: Provide data on maintenance and renewal of applied finishes QUALIFICATIONS: A. Applicator: Experience in application of similar systems and products on projects of similar size and scope MOCK-UP A. For coatings, construct mock-up area under conditions similar to those that will exist during application, with coatings applied. B. Mock-Up Size: 10 feet square. C. Locate where directed. D. Mock-up may remain as part of the work DELIVERY, STORAGE, AND HANDLING A. Deliver materials in manufacturer's sealed packaging, including application instructions. B. Store tightly sealed materials off ground and away from moisture, direct sunlight, extreme heat, and freezing temperatures. C. Store in unopened packaging in clean, dry environment protected from sunlight at 40 degrees F (4 degrees C) to 85 degrees F (29 degrees C). Prevent material from freezing FIELD CONDITIONS A. Maintain light level equivalent to a minimum 200 W light source at 8 feet above the floor surface over each 20 foot square area of floor being finished. B. Do not finish floors until interior heating system is operational. C. Ensure that substrate surface and ambient air temperature are minimum of 35 degrees F (minus 7 degrees C) and rising at application time and remain above 35 degrees F (minus 7 degrees C) for at least 24 hours after application. Ensure that frost or frozen surfaces are thawed and dry. D. Do not place surface hardener in areas without roof cover. E.

Substitutions: See Section Product Requirements MATERIALS A. Water soluble sealer/densifier, that when applied in accordance with manufacturers application recommendations will produce a dense surface resistant to abrasion, moisture, tire marking and provides added gloss to the floor finish. 1. VOC Content: None 2. Color: Clear. 3. Acceptable Product: MasterKure HD 200WD (was formerly Kure N Harden ) by BASF Building Systems. B. Substitutions: See Section Product Requirements. PART 3 EXECUTION 3.01 EXAMINATION A. Verify that floor surfaces are acceptable to receive the work of this section. B. Verify that flaws in concrete have been patched and joints filled with methods and materials suitable for further finishes EXISTING (CURED) CONCRETE A. Thoroughly repair and clean existing concrete surfaces before application. B. Ensure surfaces are clean, dry, and free of dust, oil, grease, sealers, and other surface contaminants that might inhibit penetration of treatment GENERAL A. Apply materials in accordance with manufacturer's instructions APPLICATION A. MasterKure HD 200WD is not a curing compound (film forming product), but should fully saturate the concrete surface for best results. Follow manufacturer s application recommendations. Acquire and review most current manufacturers published data. Including MSDS and warranty. B. Existing Concrete (Cured) 1. For best results, apply to concrete cured seven (7) days or longer. 2. Assure surface is clean and free of contaminants (waxes, curing membrane, oil, etc). 3. Apply undiluted MasterKure HD 200WD to saturation level by sprayer, broom or squeegee. 4. Keep the treated surface area wet with product for thirty (30) minutes by spraying additional product and/or brooming excess material from low areas. 5. Do not allow dry spots to occur. Prevent any drying of surface for twenty (20)-thirty (30) minutes. Use brooms or floor scrubber with non-aggressive pad or brushes to aid in penetration. 6. After twenty (20)-thirty (30) minutes, depending on temperature and humidity, MasterKure HD 200WD will begin to gel. Keep all treated surfaces moist, and continue brushing/scrubbing action for 5-15 minutes. At this stage, the surface can be slippery. Use caution. 7. Flush the surface with water and squeegee the surface to remove excess material and all impurities present on the surface. Rinse with generous amounts of water to enhance product performance. Finish with a damp mop. MasterKure HD 200WD is environmentally safe and may be flushed directly into drains of 4

6 8. DO NOT allow MasterKure HD 200WD residue to dry on the surface. Any product allowed to dry on the surface may cause white residue that can be difficult to remove. C. Drying Time 1. MasterKure HD 200WD penetrates in approximately thirty (30) -sixty (60) minutes depending on temperature and humidity. Allow each application to penetrate thoroughly before proceeding with additional applications. 2. Allow twenty four hours after application before opening to wheeled traffic. 3. Following drying, gloss development can be enhanced by buffing and or additional floor scrubbing CLEANING A. Clean tools immediately after use with clean water.. B. Clean up and properly dispose of debris remaining on Project site related to application. C. Remove temporary coverings and protection from adjacent Work areas. END OF SECTION of 4
