Subject to compliance with requirements, the following manufacturer offering products that may be incorporated into the Work : MATT THE MILLER’S; CARMEL CITY CENTER; SUITE 101 03 36 00 - CARMEL CITY CENTER Issue Date 03.26.12 CONCRETE STAIN MATT THE MILLER’S; CARMEL CITY CENTER; SUITE 101 a. L.M. Scofield Co., Douglasville GA, tel.: 800.800.9000. B. Products: 1. Chemical Stains: a. LITHOCHROME Chemstain; L.M. Scofield Co. b. Refer to Finish Legend on Drawings for color selection and other information. 2. Sealers: a. CEMENTONE; L.M. Scofield Co. 3. Sealants: a. LITHOSEAL Trafficalk-3G; L.M. Scofield Co. b. Refer to Finish Legend on Drawings for color selection and other information. 2.2 CONCRETE CURING MATERIALS A. Refer to Specification Section 03 30 00, 2.11 "Other Concrete Curing Materials" for information and requirements for concrete curing materials to be used in this Section. PART 3 - EXECUTION 3.1 CONCRETE PROTECTING AND CURING, GENERAL A. Refer to Specification Section 03 30 00, "Cast-In-Place Concrete" for information and requirements for concrete curing procedures. B. General: Protect freshly placed concrete from premature drying and excessive cold or hot temperatures. Comply with ACI 306.1 for cold-weather protection and ACI 301 for hot- weather protection during curing. C. Evaporation Retarder: Apply evaporation retarder to unformed concrete surfaces if hot, dry, or windy conditions cause moisture loss approaching 0.2 lb/sq. ft. x h before and during finishing operations. Apply according to manufacturer's written instructions after placing, screeding, and bull floating or darbying concrete, but before float finishing. D. Formed Surfaces: Cure formed concrete surfaces, including underside of beams, elevated or supported slabs, and other similar surfaces. If forms remain during curing period, moist cure after loosening forms. If removing forms before end of curing period, continue curing for the remainder of the curing period. E. Unformed Surfaces: Begin curing immediately after finishing concrete. Cure unformed surfaces, including floors and slabs, concrete floor toppings, and other surfaces. F. Cure concrete according to ACI 308.1.

Verification of Conditions: Contractor shall examine areas and conditions under which work will be performed and identify conditions detrimental to proper completion of the work. B. Do not proceed until unsatisfactory conditions have been corrected. 3.3 PREPARATION A. Follow manufacturer’s written instructions. B. Do not use liquid curing materials. C. Immediately prior to chemically staining, thoroughly clean the concrete. Sweep surfaces, then pressure wash or scrub using a rotary floor machine. Use suitable high quality commercial detergents to clean. Rinse surfaces after cleaning until water is completely clean. Allow floor to dry completely prior to application of floor stain. 3.4 APPLICATION OF CHEMICAL STAIN A. Concrete surfaces shall be dry and properly prepared as described above. Protect surrounding areas from over-spray, run-off and tracking. Divide surfaces into small work sections using wall, joint lines, or other stationary breaks as natural stopping points. B. Apply chemical stains full strength (undiluted) at coverage rate recommended by the manufacturer and use application equipment described in the manufacturer’s printed technical literature. The color of the liquid chemical stain has no resemblance to the final color produced on the concrete substrate. C. Chemical stains normally fizz when reacting with concrete. If fizzing does not occur, the substrate has not been adequately prepared or the concrete pH level is too low. If this should happen, contact the local representative for further recommendations. D. Transfer chemical stain to substrate by brush or spray and immediately scrub into surface. E. Reaction time depends on specific conditions. F. When multiple coats of one or more colors are required, washing and drying between colors is desirable to evaluate the color prior to the next coat. G. After the final coat of chemical stain has remained in the surface for a minimum of four hours, remove all residue by wet scrubbing with commercial grade detergent. Rinse surfaces after scrubbing until rinse water is completely clean. Run off may stain the MATT THE MILLER’S; CARMEL CITY CENTER; SUITE 101 03 36 00 - CARMEL CITY CENTER Issue Date 03.26.12 CONCRETE STAIN MATT THE MILLER’S; CARMEL CITY CENTER; SUITE 101 adjacent areas or harm plants. Collect rinse water by wet vacuuming or absorbing with an inert material 3.5 APPLICATION OF SEALER A. Concrete substrate shall be completely dry. B. Sealer shall be produced by the chemical stain manufacturer. C. Test surface pH level prior to applying sealer. D. Apply sealer according to manufacturer’s written instructions at a rate of 300 to 5000 square feet per gallon per coat. E. Maintain a wet edge at all times. F. Allow sealer to completely dry before applying additional coats. G. Apply second coat of sealer at 90 degrees to the direction of the first coat using the same application method and rates. H. Seal horizontal joints in areas subject to pedestrian or vehicular traffic. 3.6 PROTECTION A. Protect floor from traffic for at least 72 hours after final application of sealer. 3.7 MAINTENANCE A. Maintain chemically stained and sealed floors by sweeping. Clean spills when they occur and rinse dirt off with water. Wet-clean heavily soiled areas by mopping or by scrubbing with a rotary floor machine equipped with a scrubbing brush and a suitable, high quality commercial detergent. Maintain interior floors that require polishing by using a compatible, premium-grade, emulsion-type, commercial floor polish, following manufacturer’s instructions and safety requirements.
