10 BID RELEASE 2 - ADDITIONS & RENOVATIONS PART 2 - PRODUCTS 2.1 ACCEPTABLE MANUFACTURERS A. Basis of Design: Provide products specified herein manufactured by L. M. Scofield Company (Scofield). 2.2 MATERIALS A. Reactive Chemical Concrete Stain: Reactive, water-based solution of metallic salts which react with calcium hydroxide in cured concrete substrates to produce permanent variegated or translucent color effects.

Examine areas and conditions under which the concrete stain work will be performed and identify conditions detrimental to the proper and timely completion of the work. Do not proceed until unsatisfactory conditions have been corrected. B. Interior Applications: Concrete substrates must have a moisture vapor emission rate of less than 5 lbs./1000 sq. ft. per 24 hour based on a 72 hour test period according to ASTM F PREPARATION A. New Concrete: Comply with the following: 1. Newly placed concrete to sufficiently cure for concrete to become reactive. Minimum cure time is 14 days. 2. Interior Applications: Minimum cure time of concrete is 30 to 60 days, or longer if necessary to meet the specified water vapor transmission requirements. 3. Do not use liquid curing materials. Cure concrete flatwork with new, unwrinkled, nonstaining, high quality curing paper complying with ASTM C 171. Do not overlap curing paper. 4. Immediately prior to chemically staining, thoroughly clean concrete to remove any contaminants deleterious to subsequent chemical stain application. Sweep surfaces, then pressure wash or scrub using a rotary floor machine with a Mal-Grit Brush from the Malish Corporation. Use suitable, non-acidic, high quality commercial detergents to facilitate cleaning. Rinse surfaces after cleaning until rinse water is completely clean. Allow floor to dry completely prior to application of concrete stain. L&D #24036 REACTIVE CHEMICAL CONCRETE STAIN

11 BID RELEASE 2 - ADDITIONS & RENOVATIONS a. Pressure Washing: Use a pressure washer equipped with a fan tip and rated for a minimum pressure capability of 4000 psi. B. Surface Preparation for New or Existing Concrete: 1. Concrete surfaces should be completely penetrable before applying the initial application of chemical stain. The surface of the concrete should be lightly mechanically abraded to remove weak cement paste and contaminants. The final surface preparation should approximate a Concrete Surface Profile of 1, (CSP1 as designated by the International Concrete Repair Institute, Alexandria, Virginia). Methods for mechanical abrasion include: a. Pressure Washing: Use a pressure washer equipped with a fan tip and rated for a minimum pressure capability of 4000 psi. b. Scrubbing with a rotary floor machine with a Mal-Grit Brush from the Malish Corporation. c. Light sanding of the surface. Surfaces should be tested to receive stain by spotting with water. Water should immediately darken the substrate and be readily absorbed. If water beads and does not penetrate or only penetrates in some areas, perform additional surface preparation and testing. On denser concrete floors, sand lightly to open up surfaces. Retest and continue surface preparation until water spots immediately darken and uniformly penetrate concrete surfaces. 2. Rinse concrete substrates until rinse water is completely clean. C. Scoring: Score decorative jointing in concrete surfaces 1/8 inch deep with diamond blades. Rinse until water is completely clean. 1. Single Color Stain Applications: Score after staining. 2. Multiple Color Stain Applications: Score before staining. 3.3 CHEMICAL STAIN APPLICATION A. General: Comply with chemical stain manufacturer s printed instructions and current recommendations. 1. Do not mix the specified chemical stain with highly alkaline materials. Doing so will result in a dangerous chemical reaction. B. Protect surrounding areas, landscaping, and adjacent surfaces from overspray, runoff, and tracking. Divide surfaces into small work sections using walls, joint lines, or other stationary breaks as natural stopping points. C. Apply chemical stains at the coverage rate recommended by the manufacturer and use application equipment according to the chemical stain manufacturer s printed instructions. Note the color of the liquid chemical stain will not be the final color produced on the concrete substrate. D. Transfer chemical stain to the substrate by brush or spray and immediate scrub into surface. Reaction time depends on wind conditions, temperatures, and humidity levels. E. 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. L&D #24036 REACTIVE CHEMICAL CONCRETE STAIN

12 BID RELEASE 2 - ADDITIONS & RENOVATIONS F. Rinsing: After the final coat of chemical stain has remained on the surface for a minimum of four hours, neutralize unreacted chemical stain residue and then remove completely prior to sealing. After neutralization, thoroughly rinse surface with clean water several times to remove soluble salts. While rinsing, lightly abrade surface using a low-speed floor machine and red pad to remove residue and weakened surface material. Runoff may stain the adjacent areas or harm plants. Collect rinse water by wet vacuuming or absorbing with an inert material. 1. Failure to completely remove all residue prior to sealing the surface will cause appearance defects, adhesion loss or peeling, reduced durability, and possible bonding failure and delamination of sealer. 2. All stain residue, runoff liquid, and rinse water must be collected and disposed of according to applicable Federal regulations and governing authorities having jurisdiction. 3.4 SEALING APPLICATION A. Concrete substrate must be completely dry. Test surface for proper ph prior to applying sealer. A ph value of 7 or higher indicates all acid has been neutralized. If the tested ph value is less than 7, repeat neutralization step until the required ph value is achieved. B. Conduct a moisture vapor emission test prior to applying any sealer. Refer to the specific sealer s Technical-Data Bulletin for acceptable MVER. C. Apply sealer according the sealer manufacturer s printed instructions at a rate of 300 to 500 square feet per gallon per coat. Maintain a wet edge at all times. D. Allow sealer to completely dry before applying additional coats. E. Apply second coat of sealer at 90 degrees to the direction of the first coat using the same application method and rates. F. Seal horizontal joints in areas subject to pedestrian or vehicular traffic. 3.5 PROTECTION A. The General Contractor is responsible for using Temporary Floor Protection throughout the project to safeguard the surface quality of concrete slabs before and after application of decorative finishes or installations of other materials. B. All concrete floors that will be not be covered by other materials will be protected throughout the project. The concrete slab must be treated as a finished floor at all times during construction. C. Temporary Floor Protection will be removed only while finish work to the concrete is being performed and will be replaced after the final finish has cured sufficiently. D. Temporary Floor Protection will be Proguard Duracover as manufactured by L. M. Scofield Company, Douglasville, GA ( ). Seaming of the temporary floor protection will be performed with Scofield Proguard Heavy Duty Seaming Tape. Both products will be installed following the manufacturer s published installation procedures. L&D #24036 REACTIVE CHEMICAL CONCRETE STAIN

13 BID RELEASE 2 - ADDITIONS & RENOVATIONS E. Do not apply the heavy duty seaming tape to bare or finished floors or wall surfaces at any time. It will permanently damage the floor. 3.6 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, according to manufacturer s printed instructions and safety requirements.
