6 C. Assure that sub-floors are free of scale, and foreign deposits of any kind, including paint, oils, waxes, sealers, loosely bonded toppings, and curing compounds not compatible with the adhesives employed. Advise General Contractor to correct any of these conditions 1. Prepare floors to receive new flooring by washing, etching, sanding, and filling or other procedures as necessary for satisfactory installation. 2. Remove coatings, including curing compounds, and other substances that are incompatible with adhesives and that contain soap, wax, oil, or silicone, without using solvents. Do not use adhesive removers. 3. Do not allow cutback asphaltic adhesive or other non-approved adhesive, to come in contact with new adhesives. D. Ascertain the following: 1. Moisture emission rate of 3 pounds/1000 sq.ft. per 24 hours, or less according to an anhydrous calcium chloride test. 2. Vapor emission control testing per ASTM F1869 will be performed by Owner s Testing Laboratory. 3. In the event that moisture emission exceeds this limit, the Architect will determine the corrective measures, and will be performed by an authorized change order, or by a separate competitive bid. E. Assure ph between 5 and 9 when substrate wetted with potable water and phydrion paper applied. Correct condition in accordance with flooring manufacturer s instructions. F. Conduct adhesion and bond tests if recommended or required by the flooring manufacturer. G. Apply concrete slab primer in accordance with the manufacturer's recommendations if required. H. Do not use oil-based sweeping compounds. Vacuum floors again immediately before installation of carpeting. 3.2 CARPET TILE INSTALLATION A. Site and Material Condition: The floor should have a minimum temperature of 65ºF for at least 72 hours prior to installation and 48 hours after installation. Temperatures should not exceed 90ºF. Relative humidity above 65% will adversely affect the adhesive and primers. B. Floor Preparation: Comply with CRI 104, Section 6.2, Site Conditions; Floor Preparation, and carpet tile manufacturer s written installation instructions for preparing substrates indicated to receive carpet tile installation. 1. Curing chemicals, sealers, or other chemicals must be compatible with the Modular backing system, and adhesives. 2. Concrete (No Previous Flooring Material): Apply a concrete sealer coat at the rate recommended by the sealer manufacturer. Use thin, fast drying primers that are compatible with adhesives. Apply adhesive only after primer is completely dry. 3. All excess paint spots, drywall mud, or other solid debris must be removed from the floor. Completely remove all wax, dirt, grease, paint, or old adhesives including cut back adhesive. DO NOT use solvents to clean the floor. 4. Do not use oil based sweeping compound. Do not install over Resin Base Curing compound. 5. Assure that floor is flat to within 1/8 in 10 ft. 6. Fill all cracks, holes and depressions with a Portland cement based patch material. Use leveling compound when required. 7. Sweep and vacuum the floor. Smooth, nonporous floors should be damp mopped prior to installation. CARPETING

7 C. Floor Layout: 1. Divide room into four equal quadrants. Snap two white chalk lines perpendicular from each other in the center of the room. 2. Check the distance from each centerline to its parallel wall and determine how many tiles will be required. It may be necessary to shift the centerline over by 9 to make sure that the border tiles are at least 1/2 tile wide. D. Adhesive Application: 1. Glue down with releasable adhesive, or partial glue down with releasable adhesive. 2. Use adhesive products approved by tile manufacturer. Apply in accordance with Tile and Adhesive manufacturer s directions. E. Tile Installation: 1. Start from the intersection point in the center of the floor. Install the tiles in one quadrant using the chalk lines as guidelines. Fill in the area in between the two chalk lines using the stair step method. 2. Continue to install tiles in a stair step or pyramid pattern, starting at the center point. Check to make sure the tiles are properly aligned at edges during the installation. 3. Fit the tiles together by sliding them together, being careful not to trap face yarns between or under the edges of the tile. Press or roll the tiles into the adhesive. They may be removed at any time and repositioned. 4. Roll all carpet tiles with a 75 lb. or 100 lb. roller. 5. Cut border tiles from the back in accordance with tile manufacturer s directions. Use a transition strip to protect any exposed edges. 3.3 COMPLETION AND PROTECTION A. On completion of installation in each area, remove dirt and carpet scraps from surface of carpet. Remove soiling, spots, or excess adhesive on carpet with cleaning materials recommended by carpet manufacturer. B. Remove debris, sort pieces from carpet scraps to be redirected and recycled. C. At completion of work, vacuum carpet using commercial vacuuming equipment as recommended by carpet manufacturer. Remove spots and replace carpet where spots cannot be removed. Remove rejected carpeting and replace with new carpeting. Remove any protruding yarns with shears or sharp scissors. Trim all loose yarns. D. Allow the owner to select from scrap carpet remaining after the installation. E. Protect installed carpet in accordance with CRI 104, Section 16 Protection of Indoor Installations. F. Protect carpet against damage from construction operations and placement of equipment and fixtures during the remainder of construction period. Use protection methods recommended by carpet manufacturer. END OF SECTION CARPETING
