It is a single component <br />powder that is water activated. KEMROK packaged units have 30 minutes <br />of working time and will reach compressive strengths of greater than 3,000 <br />psi in 3 hours. KEMROK can be applied in ambient temperature ranges <br />from 40°F–120°F, places and finishes like traditional concrete and cleans <br />up easily with water. KEMROK has been engineered for low permeability <br />and is resistant to chemical attack by sulfuric compounds and related <br />acids. <br />Typical Applications: <br />KEMROK has been designed for horizontal, sloped and form and pour <br />or pump applications of industrial concrete infrastructure, secondary <br />containment, sulfuric acid exposure and similar. <br />Site Preparation: <br />• Substrates must be of load bearing capacity, and free from all potential <br />bond breakers such as dirt, dust, grease, oil, sealers, curing compounds, <br />laitance, loose or deteriorated concrete and any bond-inhibiting foreign <br />substances. <br />• Mechanically prepare surfaces to achieve a surface profile equal to CSP <br />5 – 7. Concrete Surface Profile as per ICRI Guideline No. 310.2-1997 <br />(Formerly Guideline No. 03732) <br />• All surfaces to be repaired should be saturated surface dry (SSD) but have <br />no standing water. Hot surfaces should be cooled and shaded while cold <br />surfaces should be heated and sheltered.Mechanically remove all loose <br />materials by suitable means such as chipping hammer, chisel, sandblast, <br />high pressure water blast (>5000 psi), or similar methods. <br />Mixing Instructions: <br />Standard Mixing Procedures (Rotating Drum Concrete Mixer). Mix at least 2 <br />units at a time (Use 4 quarts of water for 2 bag batches).: <br />1. Pre-wet cement mixer with water then drain all water from mixer (away <br />from repair area). <br />2. Start mixer - KEMROK requires a total of 2 quarts of water per 53.5 lb. <br />unit. Initially, add only 1 quart of water to concrete mixer per 53.5 lb unit <br />of KEMROK to be used. <br />3. Add pre-determined units of KEMROK, mix for 1 minute. <br />4. Add in remaining quart of water per unit of KEMROK. <br />5. Mix for 6 additional minutes or 7 minutes total. <br />6. Pour all contents into repair area. <br />7.

Working times are influenced by surface <br />temperature and repair profile. Working time can be extended by adding <br />Aquafin’s Set Retarder Admixture to mix water. (See Set Retardant product <br />data sheet for more information). <br />• Minimum profile thickness is 1.25” (3.2 cm). There are no restrictions to the <br />depth of the repair profile. <br />• For best results, Aquafin recommends monolithic placement of repair <br />materials. Maintain a minimum thickness of 1” if repair material must be <br />layered. Material must also be layered before final set has been reached. <br />• Upon initial set, a broom finish can be applied. Upon final set, the material <br />can be saw-cut, drilled, sanded and/or polished. <br />• Do not re-temper. The addition of water to the surface of the repair will <br />negatively affect the materials final properties. <br />• General loading in 2 hours for wheeled traffic and 1 hour for foot <br />traffic after addition of water. Add 30 minutes for every 10°F drop <br />in temperature. Contact Aquafin Field Engineering for Cold Weather <br />Applications (40°F/4.5°C and below). <br />• All previously existing joints must be re-established within 2-3 hours of final <br />set. <br />• Self-curing, (Protect with blankets or equivalent in ambient temperatures <br />below freezing (32°F/0°F), water curing not required or recommended. <br />• Clean all tools and equipment with water prior to the material reaching <br />final set.</p> <p>LIMITED WARRANTY: AQUAFIN, INC. warrants this product for a period of one year <br />from the date of installation to be manufactured free of defects and to be consistent <br />with its technical properties as stated in our current Technical Data Sheet.
