THIN PATCH A one component, modified polymer, cementitious, surface leveler and repair material. MANUFACTURER: A.W. Cook Cement, Inc. 242 Amy Industrial Lane Hoschton, Ga. 30548 (706)654-3677 fax (706) 654-3662 1. GENERAL USES: For leveling and repairing deteriorated concrete. Thin Patch may be used above or below grade and on horizontal or vertical surfaces. From 1/8" to 1/4". 2. FEATURES: One component. Superior adhesion. Similar modes of elasticity to concrete. Extremely low shrinkage. Vapor permeable. Resistant to freeze/thaw cycling. Easy to apply and finish. May be feather edged. 3. INSTRUCTIONS FOR USE: A. Surface Preparation: All surfaces must be clean and free of dirt, dust, paint, sealers, coatings, loose material, adhesives, curing compounds or any material that will inhibit patching material from coming in contact with the concrete pores. Tight, steel troweled concrete should be abraded or etched with sulfamic or muriatic acid solution, then neutralized to open up the concrete pores. Removal of any anti adherents or loose materials must be accomplished mechanically with a wire brush, chipping hammer, or by sand or water blasting. Solvents or strippers are not acceptable. B. Mixing: For normal applications, add 7-1/2 to 8-1/2 pints of water per 60 pound bag of Thin Patch, depending upon the desired consistency. Mixing can be achieved either manually or mechanically. Mechanical mixing is preferred for quantities greater than 1 bag. Mixing should continue until a uniform, lump-free consistency is obtained. Avoid over mixing which could lead to over aeration of the mix. Do NOT add more water than specified nor add additional powder from other units. C. Application: Dampen the surface thoroughly with clean water. Avoid standing water. Then prime it with a slurry of Thin Patch using a stiff brush. The recommended slurry consists of 10 pints of water per 60 pounds of Thin Patch. Protect from rain until initial set has been achieved. D. Curing: The formulation of Thin Patch minimizes the need for curing. However, application in direct sunlight or windy conditions may lead to rapid surface drying. The use of light water fogging for 48 hours or a water based compound that complies with ASTM C-309 is recommended. Do not commence fogging until initial set has been reached; typically 1-2 hours depending upon ambient conditions. If a water based curing compound is used, this must be removed or allowed to degrade prior to overcoating. E. Limitations: Ambient and surface temperatures must be 38°F or above during application. Minimum thickness: 1/8 inch. Maximum thickness: 3/8 inch. F. Clean Up: Remove uncured Thin Patch from tools and equipment with water. Cured material may only be removed mechanically. 4. PACKAGING: 60 pound bag. 5. STORAGE AND HANDLING: A. Shelf Life: 12 months in the original unopened container. B. Storage: Store in a dry area away from direct sunlight. The product should be conditioned to between 40° F and 95°F before use. 6. HEALTH AND SAFETY: A. Health Precautions: This product contains Portland cement and crystalline free silica. Avoid breathing the dust. Exercise care; as with handling any chemical construction product. B. Safety Precautions: Use adequate ventilation. Use of a NIOSH/ MSA approved dust respirator, safety goggles and chemical resistant gloves are strongly recommended. Remove contaminated clothing immediately. C. First Aid: Skin Contact: wash thoroughly with soap and water. Eye Contact: flush immediately with water and contact a physician. Respiratory Problems: remove affected person to fresh air immediately and contact a physician. Hygiene: wash hands immediately after use. Wash clothing before reuse. D. Spills: Collect in appropriate container. Uncured material may be removed with water. E. Disposal: Dispose of in accordance with local, state or federal regulations. F. Warning: KEEP CONTAINER CLOSED WHEN NOT IN USE. KEEP OUT OF REACH OF CHILDREN. NOT FOR INTERNAL CONSUMPTION. FOR INDUSTRIAL USE ONLY BY A QUALIFIED TECHNICIAN. Consult the Material Safety Data Sheet for further health and safety information. 7. WARRANTY: We warrant our products to be free of defects and manufactured to meet published physical properties. when cured and tested according to ASTM and CEMTEC standards. Under this warranty, we will provide, at no charge, product in containers to replace product proved to be defective, when applied in accordance with our written instructions and in applications recommended by us as suitable for this product. All claims concerning product defects must be made within twelve months of shipment. Absence of such claims in writing during this period will constitute a wavier of all claims with respect to such product.
